Ideated individuals are those who have manifested an Idea. For examples, you can view Auspice's gallery of previous forms for their Edeia. These individuals have varying levels of identification with their Idea, and varying levels of identified vs. introjected regulation. Those who have greater levels of synchronicity of identity with their Idea, and with greater levels of identified regulation when expressing an Idea, tend to have more powerful abilities and more alterations in appearance. They often have reduced physical needs (food, sleep, etc.) and may slow or stop aging. 

Ideated individuals can have an extremely high level of attunement to their Idea without Actualizing; perhaps they more or less fully identify with their Idea but simply choose not to step across the threshold to Actualize. They can also purposefully aim towards deeper identification with their Idea to gain powers, though there may be consequences (see the Magic and Side Effects subsection). Being on the borderline of Actualization can be uncomfortable, however, like their skin does not quite fit, or that they are sitting on the edge of a cliff without any railing. The exact feeling differs from person to person, and they can learn to tune it out, but it would be undeniably present. Most of those at the edge instinctively withdraw and re-identify with their identity as their current species, at least somewhat, to settle back into their skin.

Magic and Side Effects

The magic of ideated individuals tends to be significantly weaker than they would as an Edeia, and they can experience side effects when using their magic. The more powerful an ideated individual's magic, the more side effects they tend to experience when they use their magic. If they do not use their magic, they can avoid the side effects, but greater power also often comes with decreased control. Powerful ideated individuals may have passive abilities they cannot control, or their abilities might activate by instinct if they feel that they are in danger or if they sense a "target," whether consciously or subconsciously. (For an example of a "target," an individual with a high level of latent malice could be a target for someone with an Idea of Malice, and the one ideated with Malice may instinctively draw out the target's malice.) 

The side effects of idea magic are a result of the energy of idea magic causing instabilities in the connection of the soul to the "body," whether that is a biological body, an aggregation of energy, or a computer/hard drive for a digital being. This can manifest in all sorts of ways, both physical effects (tiredness, dizziness, hunger, specific cravings, body aches, loss of sensation and/or locomotion, etc.) and psychological effects (intrusive thoughts, odd dreams, nightmares, a sense of dissociation from their body, anxiety, confusion, etc.). For the most part, these effects are temporary, though there may be some slight shortening of lifespan. 

When an ideated individual starts overusing their magic (high intensity over a short time or prolonged usage without enough rest), they tend to lose consciousness as an instinctive safety mechanism. If they push through it through sheer force of willpower, side effects more be more severe and cause long-term effects, such as drastically reduced lifespan. In an extreme case, the individual's soul may be cleaved from their body. An Edeia could grab the soul and put it back, but the individual would be essentially vegetative for several days to weeks and their lifespan would be drastically reduced. While ideated individuals tend to have an extended lifespan, there is still a limit. Depending on the person, they might not appear to age, but as they near the end of their life, they might become more and more lethargic, dissociative, or ill in other ways before losing consciousness and not waking up. As a note, effects on the body tend to be more dispersed; decaying and dissolving of parts of the body tends not to occur unless the effect is related to the individual's specific Idea magic. 

Some individuals may employ various methods to reduce side effects. For instance, if they are granted immortality by another Edeia, they do not have to be concerned about lifespan. However, something always manifests. The only kind of "body" 100% compatible with an individual's Idea magic is their Edeia form. 

Appearance Alterations

An ideated individual often, but not always, manifests changes in their appearance. This is both an adaptation that allows their body to tolerate the energy of idea magic better, and also a manifestation of their self-image and interpretation of their Idea. The more the body changes, the less severe the side effects. Still, there is a limit to how much the body can change, and the side effects for powerful abilities or intense/prolonged usage would likely be severe. While lifespan is usually much extended for Ideated individuals, taxing the body so much could lead to that extended lifespan being shortened somewhat. 

An ideated individual can subconsciously adjust the "throttle" for change; that is, if they are more welcoming to changes, more changes will occur and the more significant they are. However, changes are much slower to reverse; this generally only happens if there is a drastic disconnection from the Idea. Eye color typically changes first, though later on, hair color and skin color may change. In rare cases, there can be drastic changes in physical form. If an ideated individual's magic is unstable (whether caused by emotional instability or lack of control over the magic), then drastic changes can be more likely.

Below are some examples of the types of changes in appearance an ideated individual can undergo. Many individuals only go so far as minor changes; some manifest major changes of one type without any changes in another - for instance, Thaene manifesting a halo (major anatomical alteration) but not any changes in the coloration or material of his body.
