Edeiology is the study of Edeia's abilities, life cycle, and overarching metaphysical traits. Edeia "biology," if you will.

Edeia are pure energy beings composed of idea magic. They require no sustenance to live, do not age, and cannot be killed, though it is possible for their existence to end through dissociation. 

They are typically tangible in how they interact with the world. They do exert contact force and feel solid, but this is due to their magic and energy as opposed to actual matter interactions. They can alter whether they are solid or not, and even alter whether they are visible or not - though some may be better at it than others.

One important point about Edeia is that they are who they want to be, or if some big change occurred that would change their identity (since they become their "true self" at the moment of Actualization, though this "true self" can be mutable), they are at least transitioning to who they want to be. If they have an existence they fundamentally do not want, the nature of their existence will change to reflect that desire. 

Idea Magic

Idea magic is the magic of Edeia, magic that comes from the power of ideas. One must first acquire or have an Idea and then develop their affinity to it to eventually Actualize into an Edeia. 

Approximately 10% of the human population native to the world of Ideation is capable of idea magic. Some are born with their Idea, and some develop one through strong affinity to an abstract concept. Some are granted an Idea, or the potential to develop one, by Ideation.

Every Idea can manifest differently, so it can be difficult to define any common patterns in the magic. Before Actualization, the magic is considerably weaker and the ability to manipulate energy is limited. 

How powerful idea magic is is determined by how strong one's affinity to the Idea is, and the interpretation of the Idea. The most unique aspect of the idea magic system as opposed to other systems is that one's perception of the Idea can greatly determine its capabilities. The general rule of thumb is: if you can imagine it to be so, it can be so. (But you can always run character abilities by Auspice first, if you like.)

An important note: one needs not to personally experience the idea in order to have a high affinity to it. For example, Malice is not malicious but strongly identifies as the concept of malice itself.

Idea Ability Guidelines

Generally, anything that you can imagine as related to the Edeia's Idea and identity could fit. However, there are a few caveats to keep in mind. 

• Against other Edeia / Idea Magic. Idea magic effects tend to only ever be partially effective on other Edeia, unless the subject Edeia deliberately chooses to welcome the full effect. You may describe an ability as having an absolute effect, but please keep in mind that it is only absolute for mundane/non-Edeia beings who have no magical ability to resist. For Directly Oppositional Abilities - there are times when the effects of Idea magic may have opposite or opposing effects. This often ends up being a matter of whose willpower is stronger and/or who cares more about the result. As a meta note, these opposing cases can be discussed between owners to determine what the results could be - and they could change depending on the situation. Other sorts of edge cases and unusual circumstances with Edeia could also be discussed.  

  • In Abstractions, the Edeia the Abstraction belongs to has a significant "advantage" - the very dimension is a reflection of the Edeia. Only the host Edeia can truly metaphysically manipulate the reality of that space, and define the rules. A visiting Edeia does not have no chance of resisting various effects, but it would be much more difficult for them if conflict arose. 

  • In personal dimensions and other magical areas created or shaped by an Edeia, the situation can depend on how closely and actively linked those dimensions are to the Edeia. If the area is something an Edeia creates and no longer has any connection with besides having created it, the space is fairly neutral. If the creator Edeia continued to visit, maintain, and/or shape it, the area provides advantage to that Edeia. Nonetheless, it is something open to imagination and interpretation of circumstances. 

• Other Ideas being utilized in an Edeia. There are some circumstances in which an Edeia may be able to use the Idea and associated abilities of another Edeia or a non-Actualized individual, such as by mimicking the ability. There are some things to keep in mind, however: 

  • An Idea cannot be "stolen" from an Edeia, though their abilities can temporarily be suppressed and/or copied. It is encouraged to have some conditions (such as how Ki and Ro need access to contrasting Ideas in order to copy Ideas) or limitations (time limit, only partial copying, etc.). It may be possible to "steal" an Idea from a non-Actualized individual, but this is generally still not permanent, as it is a facet of their being; this may manifest as them losing touch with their Idea for that time and losing their associated magical abilities. The emptiness in them may lead to introspection and re-formation of their identity, which remanifests/returns their Idea to them. 

  • It is discouraged to have other specific Ideas be permanently part of an Edeia's magic. However, if you feel that this is crucial to the character, then please keep in mind a few things: the Ideas should either be not explicitly stated and/or not on the Edeia Masterlist, unless you have the explicit permission of the owner of the Edeia with the existing Idea to use that Idea for your Edeia character permanently. You also do not have any claim to the Ideas that are used and Edeia can be made from them, but the new owner of the Edeia with that Idea cannot demand that you remove that Idea. 

• Omniscience. Generally, abilities involving omniscience or something similar can access indisputable facts about the universe(s) and world(s) without difficulty. That said, there may be barriers when it comes to personal knowledge. For general Edeia, there may simply be resistance to gaining personal information about them from them, leading to fragmented or incomplete information. For those who specifically have magic to obfuscate/hide information, that should be discussed if you wish it to be addressed - an Edeia truly committed to keeping their personal information private will likely have it so, going so far as to make it inaccessible even from other sources.

• Alternate Timelines. Abilities that span timelines are very rare, and should be clearly linked to the Idea. While alternate timelines have a purpose of opening up more possibilities of backstories, they do also serve a purpose of having independent stories that have minimal interference with each other - too much mixing can make that difficult. 

• Souls and Sentience. I would prefer that Idea magic is not able to directly create souls. However, they can catalyze the development of one. It is possible for Edeia to grant sentience, though this is also not common and should also be directly relevant to the Idea. There is a difference between gaining sentience and gaining a soul; a being that gains sentience could develop a soul as they develop their own will. An individual with sentience and no soul could be able to process sensations, some emotions, and experiences, but tend to almost follow some sort of "program" rather than having a mutable self-determined will, and may be lacking in certain aspects of individuality. Those with souls can find and change who they are, transform themselves metaphorically and metaphysically. Consciousness essentially grants sentience, and as the newly sentient being processes all their experiences they may gain their own will and their soul develops as a natural process. Ego can influence a sentient, soulless individual to develop a will, which could speed the whole process along. 

• Fourth Wall. I do not wish to make the Edeia universe canonically and with absolute certainty a creation of us in this world. There can be a universe that just so happens to have us describing and "creating" these characters, and our decisions seem to reflect in their reality - but canonically, the causation cannot be absolutely determined. Are we actually defining these beings, or is there some other metaphysical force that unites these realities in such a way? Mechanically speaking, it's still the same as breaking the fourth wall, but I just am not too keen on a canonical fourth wall. An Edeia with this sort of ability can choose to interpret this as "breaking the fourth wall," though.

Abstraction

An Edeia's Abstraction is their personal pocket dimension, a place that reflects their soul and Idea. It is created upon Actualization, and the initial form it takes can depend on if the individual has an existing personal mental space (such as a mind palace) as well as the individual's personality, preferences, and Idea. After it is formed, the Edeia can redecorate, so to speak—changing the landscape, adding new objects, etc. Typically, any changes are still done within the "space" of the original Abstraction; fundamental alterations like changing a void into a replica of a place on the physical plane is not typically done. 

You can see a gallery of Abstractions made by Auspice here. 

An Abstraction can also be used as a bridge for teleportation—since the dimension is not spatially attached to the physical plane, one can enter and exit at any location. Getting this to be precise is difficult, however, and typically only used for long distances.

There are two ways for a physical/organic being to enter an Abstraction—as a soul/energy form or physically. Physically entering an Abstraction is more difficult, taking more energy/effort from the Edeia and causing more stress to the physical body (which can be recovered from without issue, as long as one is not dimension-hopping every day or at a similar frequency). Entering as a soul is easier. Edeia can either remove a soul from a body by touching the subject and pulling it out, or simply getting a "hold" on the soul before transporting to the Abstraction. There's no preparation that's particularly necessary, but one probably wants to make sure their body is going to be somewhere safe. It enters a sort of stasis without a soul—metabolic needs such as eating/drinking/aging/etc. will slow over the course of a few hours before halting entirely.  If too much time is spent away, returning to the body becomes increasingly troublesome. It takes longer to wake up, there is lasting lethargy (which will go away after some time), and one may experience something like dissociation (in the human sense, not the Edeia death sense) in which the soul somewhat drifts/loses synchronicity with your body.

Abilities

All Edeia share a number of abilities, including shapeshifting, intangibility, invisibility, their ability to use their Abstraction for teleportation and dimension crossing, energy manipulation, soul manipulation, etc. They are detailed below. 

Form Manipulation

Shapeshifting

Edeia are capable of shapeshifting. However, they tend to be most comfortable in their natural form, as that form reflects their Idea and the nature of their soul. Some may have an alternate form that they are about just as comfortable in, but that is less common. 

Their colors can be changed. For some Edeia, it is a simple matter, but for others, it may be more difficult. 

In terms of temporary shapeshifting, there are very few limits. Many will take on a humanlike form to mingle with mundane society or other reasons.

Intangibility/Invisibility

Edeia can manipulate the characteristics of the energy that manifests as their body, though some may be better at it than others. Generally, they can make themselves fully intangible or partially tangible (i.e. there is a resistance to passing through them but one still can); most are fully solid by default but this is not necessarily the case. 

They can also manipulate themselves to be partially or fully transparent. Note that "selective" invisibility (in which certain individuals can be "chosen" or only individuals under certain conditions can see or not see the Edeia) can only occur as part of the Edeia's Idea magic; natural invisibility is a manipulation of the way light interacts with them, which is more of a physical phenomenon than a magical one. 

Dimension Crossing

Edeia have a single world of origin, but they are able to cross dimensions—as such, Edeia are capable of interacting with any character you wish. Typically, this is done by using their Abstraction as a bridge, since these pocket dimensions are slightly removed from reality. After entering a new dimension, an Edeia can use that dimension’s energy signature to easily identify and cross to that dimension once more. Edeia can also bring objects and entities to and from other dimensions. 

What an Edeia can do is cast out their natural Edeia energy senses for the "wavelengths" (or however the Edeia perceives them) of different dimensions, and then reach out and connect to it; every dimension (including Abstractions) essentially has a unique signature they can detect. They can then let that connection pull them to the dimension, or use it to form some kind of "door" in their Abstraction that they and others can use.  

(As for beings of other dimensions: if they have their own way of dimension traveling, that would work. Alternatively, Edeia can bring them from the different dimension to their Abstraction, and then to the world of Ideation.)

Energy Manipulation

Edeia have some degree of manipulation over many natural energies of the world, including light, sound, heat, electricity, gravity, etc. Note that if their Idea is relevant to some energy, the only limits are their imagination; this applies to the general case of all Edeia. 

They generally have the most control over light, and the sound manipulation is often to the extent of synthesizing their voice. Heat manipulation can change how warm or cool they feel upon contact (this can be subconscious or conscious control), and they can affect the environment to a small extent. They can have some amount of influence over electronics, though often very little; they can direct existing electrical flow to some extent, like redirecting lightning.  They generally have little influence over gravity when it comes to the environment or other beings, but they can change how gravity affects them. 

Edeia can also have some amount of power to manipulate soul energy. This means that they can remove a soul from a body, interfere with soulbonds, use energy from souls, sense souls, etc. However, if an individual is resistant to their manipulation, then it can be difficult to affect them. The ability also allows them to interfere with dreams, though some are better and some are not good at it at all, and more involved dream manipulation can be part of their Idea magic.

Metaphysical Manipulation

This ability relates to their powers over their Abstraction. They can change the "rules" of reality in their Abstraction, such as changing how time and space might behave. They can create portals to their Abstraction or make a physical space linked to their Abstraction. 

Generally, they have very limited power in influencing physical reality outside of their Abstraction, unless it is related to their Idea. 

Combat

Edeia are capable of combat using energy and form manipulation or their unique idea magic. 

They can shift parts of their body into offensive forms such as blades and claws. They would also be able to form energy projectiles to attack others, with the energy being the unique "flavor" of an Idea. 

Edeia can only be harmed by magic, with idea magic being most effective. Getting cut or blasted with magic would cause a sensation like pain and some destabilization. Restabilizing takes energy, and complete destabilization and/or exhaustion would lead to an Edeia losing consciousness and form and regaining it in their Abstraction. 

To defend themselves, Edeia can create energy shields capable of blocking attacks. These may take different appearances depending on the Edeia. While this also takes some effort, the tiring effect it causes is not as bad as taking "damage," so to speak. 

Of course, each Edeia can have unique ways of attacking and defending in addition to these "default" options by using their unique forms or idea magic.

Abstraction Containment / Abstraction Jail

Abstraction containment, also known as Abstraction jail, is a process by which a convergence of Edeia comes together to restrict an Edeia's activities by containing them in their Abstraction. 

Containment Conditions

During containment, the subject Edeia can do anything they want inside, but the Edeia has restrictions on leaving their Abstraction; the exact conditions are decided by the convergence of Edeia that will perform the containment. Some of the conditions are as follows; some conditions can overlap. 

Containment Level

• Full containment: cannot leave Abstraction at all. 

• Partial containment: can leave Abstraction for small periods of time, under certain conditions, and/or with an Edeia involved in the containment. After a certain amount of time or by the will of the Edeia involved in containment, the subject Edeia will be pulled back to their Abstraction. 

• Containment from Ideation: cannot enter the mundane plane of Ideation, but can enter other dimensions, including others' Abstractions. 

As the containment grows weaker, full containment could devolve into partial containment and/or containment from Ideation. 

Isolation Level

• Total isolation: no one else can enter or leave the Abstraction, and the Edeia cannot communicate with the outside. 

• Restricted correspondence: the subject Edeia can communicate with those involved in their containment. This could involve certain restrictions, such as only sending a limited number of telepathic messages with a limited number of words. 

• Open correspondence: the subject Edeia can indirectly communicate with anyone of their choosing with whatever means they have available. Some might influence dreams, some might send telepathic messages, some might create magical constructs to communicate, etc.  

• Restricted visitation: certain individuals (usually Edeia involved in containment or rehabilitation) can enter and leave. 

• Open visitation: anyone other than the subject Edeia can freely enter and leave. Of course, the subject Edeia has the choice of allowing them to enter or not. Even those involved in containment can be barred from properly entering their Abstraction, though they could be at the "doorstep" with an unignorable presence.   

As the containment becomes weaker, total isolation and other restrictions can devolve. Generally, open correspondence occurs before open visitation. 

End Conditions

• Time: the Edeia involved in containment can set a time frame for the containment to end. The containment will rapidly unravel once that time frame arrives, generally in a range of years. The Edeia involved may or may not feel the containment becoming undone, depending on how much of their essence is still linked to the containment at that time.  

• Condition: a certain condition can be set for the end of containment, such as "the end of Secrecy" or "rehabilitated enough." This functions similarly to indefinite containment, except for the fact that after the condition is fulfilled, the containment will immediately unravel. The condition can be objective or subjective; objective conditions do not require the knowledge of the Edeia who took part in the containment, while subjective conditions require the acknowledgement of the Edeia. As each Edeia acknowledges the condition is met, the containment grows weaker; it can be broken before all Edeia agree. 

• Indefinite: the subject Edeia is contained for as long as the participating Edeia can maintain the containment. Depending on how many Edeia are involved, their willpower, and the subject Edeia's willpower and degree of opposition, this could last a few years to centuries, millennia, and more. The power of the containment naturally grows weaker over time and with opposition, and cannot be "refreshed" so long as the Edeia is not subdued again, which cannot be done while they are in their Abstraction no matter how many Edeia come to try. The subject Edeia, if they want to escape, will have to try to break out at some point; if they wait long enough, the containment could be as weak as tissue paper. That said, there could be Edeia who accept their containment and live out their existences with that tissue-paper barrier by choice—perhaps only poking a few holes in it to allow visitors or the occasional trip outside. 

Mechanics

Abstraction containment requires that the subject Edeia either submit to the containment, or exhaust their power and dissipate, after which they will re-form in their Abstraction. Then, a group of multiple Edeia must use their powers of metaphysical manipulation to lock the subject Edeia in their Abstraction.  

If an Edeia escapes to their Abstraction before exhausting their power entirely, then they may be able to resist some of the effects of containment. For instance, Omephagos fled from a confrontation into their Abstraction, and they were able to avoid being completely contained but were still prevented from re-entering the mundane plane of Ideation for a time.  

The more the subject Edeia is resistant to the containment, the more Edeia need to be involved in the containment process. If the subject Edeia is willingly submitting to the containment, as few as two Edeia can be involved, but usually there are at least three in case the subject Edeia changes their mind and starts opposing their containment. There have been as many as ten or perhaps more Edeia involved in containing particularly troublesome Edeia. More than that becomes unwieldy, as aligning that many wills becomes difficult and the influence of other Edeia on the subject Edeia becomes saturated. There is something of a logistic curve to "strength of containment vs. number of Edeia involved." 

When Edeia take part in containing another Edeia to their Abstraction, they link some of their own metaphysical essence to the subject Edeia's Abstraction. Some Edeia are better at this than others; each Edeia can merge a small part of their essence with that of the subject Edeia, allowing them some degree of influence, and when enough Edeia do this, they can gain enough influence to lock an Edeia away. However, no matter how many Edeia are involved, they cannot influence what happens inside the Abstraction; they can only create a metaphysical "layer" surrounding the internal workings. 

The Edeia involved usually need to discuss the containment conditions beforehand so that their wills are synchronized. It is possible to try to sabotage the process of containment by changing the target conditions or pulling out, though if a large number of Edeia are involved, a few changing their minds or sabotaging the process will still allow the containment to take effect. Also, during the process of containment the Edeia involved can sense the intent and wills of others involved, so the saboteur may face their own judgement for doing so. Once the containment is complete, it becomes very difficult to sabotage independently, though a majority agreement of those involved in the containment can allow for a change in the conditions. 

If the subject Edeia does not try to oppose their containment, then the Edeia who took part in the containment will not be very affected by this link. The containment will naturally unravel when the agreed-upon time comes; it also becomes weaker as the essence of the involved Edeia naturally separates and returns to the original Edeia. You can think of it like a suspension of oil and water gradually separating over time. Edeia who have exceptionally strong willpower and have a commitment to keeping the Edeia contained can maintain the level of their link to the subject Edeia. 

However, if the subject Edeia is often trying to oppose the terms of containment, then the Edeia involved in the containment will feel the pull on their attention and power—especially rebellious Edeia, as such, can be very draining to contain. Then, it becomes a battle of willpower. To be involved in containing troublesome Edeia is truly a commitment of mental and magical resources; as such, many Edeia might decline to be involved in the containment process of such Edeia while still helping with subduing the Edeia. 

Consistent and intense rebellion can gradually expel the influence of Edeia involved in the containment, which could gradually loosen the restrictions. This rebellion could involve the Edeia trying to use their powers of metaphysical manipulation to poke holes in or destroy the metaphysical barrier around their Abstraction, trying to leave despite being bounced back, expelling a lot of energy to try to degrade the influence of other Edeia in their Abstraction, etc. It is easier to partially degrade the barrier or poke holes in it than it is to break it down completely. 

If the restrictions on Abstraction containment are loose from the start (for instance, allowing the Edeia to go to other dimensions) then it becomes more difficult to oppose the restrictions in a way that will cause them to break down faster. Metaphorically, you can think of it as trying to break a cage made of metal vs. breaking a cage of soft material; a hard material could break and deform from damage, but a soft material will just go along with the motions without actually being damaged. Of course, there are Edeia who have exceptionally strong willpower in containing other Edeia; Order is one of them, though they tend not to partake in containment unless they feel their presence is necessary. How effective containment is can be something that is flexible and discussed between owners of Edeia making these stories. 

Fusion

Edeia are capable of fusing. The entity that results is able to use some extent of the components' abilities, in addition to unique abilities that come from a combination of their Ideas. 

New fusions choose their own names—some use a mashup of components' names, while others choose a new name that reflects their new self.

What the resulting fusion is like depends on a number of factors: how the personalities mesh, how much the components trust each other, how compatible they are (which can depend on a number of factors). 

• Well-formed fusions between Edeia who trust each other have a single consciousness with the memories of the components and a personality that is a mix of the original ones. These fusions can be maintained for long periods of time, even longer the more the fusion is done.

• Less stable fusions between Edeia with incompatible elements or a lack of trust can result in a personality that is some blend of singular and multiple. These are harder to maintain, and thus diffuse (unfuse) easily. Strong, conflicting emotional turmoil (i.e. if components have strong but different reactions to something) can cause a stable fusion to become unstable. 

• Forced fusions are possible but highly unstable and difficult to maintain. The instigator would be the dominant personality, but they would still have elements of the subjugated component's personality. The subjugated component can fight for control, however, and when they succeed in taking the reins, the personality would be opposite, dominated by that component. 

• Fusions with other beings are possible; other energy beings are the easiest and organic/physical beings are more difficult. The appearance of a fusion with a physical entity will be dominated by the physical component - that is, an Edeia-human fusion would be mostly human-shaped. 

• Multi-fusions are also possible, given that all the components are fairly compatible. The more components there are, the more difficult it is to perform successfully and maintain. 

When Edeia unfuse, memories tend to be maintained, though the clarity can vary. Stable fusions will have very clear memories while forced fusions could seem something like a fever dream for the subjugated component.

Permafusions

Permafusions are Edeia fusions that are extremely stable and can be held indefinitely, or nearly so. It generally takes time for well-formed fusions to reach the state of "permafusion" as the Edeia become used to being one cohesive entity - after all, they are originally two individuals with their own minds, wants, and needs. Note that "Permafusion" is more a label than a true state of being. Fusions may choose to call themselves that if they feel it fits, whether they are fused 99% of the time, 80% of the time, or even less. 

The most defining trait of a permafusion is that it can be maintained indefinitely, or close enough to it, but those who have this capability may choose not to call themself a permafusion for any reason. For instance, they may not spend much time fused even though they can.

Permafusions who interact with reunited society regularly may be asked to create their own registry entry; fusions can generally make an entry on their own and make a note that they are a "permafusion." You may also let Auspice know if you want to make a fusion a permafusion, and they can add that note to the Masterlist. 

Abstractions for Fusions

When Edeia fuse, the Abstraction is a bit of a mix of the components', but the fusion can alter it at will once they enter. Depending on how stable the fusion is, it could be a perfect blend or patchwork. If the fusion "redecorates" their fused Abstraction, it will maintain that state of being when the fusion is undone and redone. 

Fusing with a non-Edeia could lead to an Abstraction with traits influenced by the other. It would be reflective of the being's headspace; for instance, if they have a mind palace or anything similar then the Abstraction would mix with that. With a more unorganized mind or animal, the Abstraction could become extremely abstract. For instance, Song's lake could become a place with floating rocks and streams that float in space, defying nonexistent gravity. The fusion could still alter the place at will after the fact, but something like that would be the starting point. 

The Abstraction resulting from fusion with a being with a mental illness would depend on the type of illness, but a possibility is a very chaotic Abstraction. Lots of moving parts, things spontaneously disappearing and appearing.

Edeia would have trouble fusing with beings of low intelligence/consciousness, considering that fusion is easiest with trusting, consenting parties. But, theoretically, if it was successful, the Abstraction might become very sparse - that is, much of it becomes empty nothingness. Also, the overall intelligence of the Edeia would be not as high. It might feel like a dream, where one somewhat in control but also somewhat watching what is happening.

Special Traits

Special traits for Edeia include the states of being Fission Edeia, Soultwined Edeia, and Tuplet Edeia (i.e. Twin Edeia). See the lore for them here.
