Mimic
The Mimics are a slime-like race of creatures formed of flexible, durable, rubber-like black ooze. They're capable of copying the shape and functions of other sentient races, and as their name suggests, mimicking them.
Origin
The Black Meteorite of 1745AC carried a particularly elusive substance that binds to its host and learns from them, and has in rare instances produced variations of the race infamously referred to as the Mimics. In a ritual performed by the Twilight Coven, it was pulled towards Esshar and nearly impacted the country to devastating effect, but a group rallied by the efforts of Myllenoris prevented the vision they foresaw. Nonetheless, fragments of the meteorite crashed around the ritual and culminated with the peak of it, where several hundred ichorous entities were given life and purpose.
Their initial moments of life were shaped by the binding magic of the Seven Sins. The end result was a hivemind of Mimics working under the newly formed Doppelgangers, and the Twilight Coven.
Physiology
Mimics are masses of mana and circuits sustained in an orichalcum-like black gel in their innate form. Their anatomy in base form consists of a webbed ball of plasm threaded with mana circuits, around a small central, chambered cyst. It beats and cycles fluid, and serves the function of both brain and heart inside of a mimic. The destruction of this piece means death for a mimic, and wounding it often spelling out permanent brain damage. Mimics often choose to form eyes from their mass, this is only done while conscious.
Their bodies are incredibly flexible. They can become as thin as paper or expand as large as a rhino. When not altering their form, a Mimic is typically 3 feet in height, but this does vary.
Any mimic can be frozen, instinctively slowing and eventually coming to a half in any temperature that would risk frostbite in humans. Mimics are often preserved like this before they can melt for study, before their body loses cohesion. This process is considered to be unpleasant for mimics, and intensely horrifying, losing their ordinarily complete control over their bodies. Using ice magic on them tends to be incredibly effective, slowing down their bodily functions and returning them to an inert state.
In their base forms, they have no need to consume food and are capable of surviving on a minimal amount of water alone, which they absorb into their bodies. They also do not require oxygen and are able to swim for extended periods... up to several days for the typical Mimic. When they copy another organism, however, their physical needs and limits adjust to that race.
When death is approaching, most mimics will instinctively revert to their base form, although this is not always the case. At the moment of death, a mimic's body loses cohesion, their circuits withdrawing from their body and coalescing. When 'decomposed', mimics leave behind congealed, ichorous puddles and a hardened black crystal chunk, the condensed form of their mana.
Shapeshifting
As capable shapeshifters, Mimics are able to assimilate with other lifeforms in a painful process where thousands of tiny needless form and poke into the subject, siphoning their blood. The process takes roughly a minute, and leaves the subject especially fatigued.
Mimics begin with a lone template, the first person they forcibly assimilated by instinct, which becomes their humanoid base form. It might be a traveller they encountered in the wilds. It's often a non-magi, and thus purely for appearances.
They do not inherit memories via mimicking. Only an exact physical replication and powers of their target, which seem to come naturally to a Mimic. The form will expire, along with its powers, if replaced by another.
Mimics are incapable of copying the powers of racial entities. No mimic spawned from the crash site is capable of the natural power of the spirits' blessing.
Mimic Ichor
Mimics bleed black instead of red; their 'blood' is a thick, ooze-like substance, no matter what form they take. Although in non-stressful situations a mimic can focus their blood into any hue, combat and any break in concentration will cause this temporary measure to fail. Their ichor is also highly corrosive when threatened, capable of eating away wood in objects such as ships in little to no time and similarly being capable of melting through flesh and bone. Mimics can control their level of acidity at will as well though, but by default, the typical mimic is highly acidic.
Mimic acid cannot eat through glass, and as such, glass is often used in order to contain hostile mimics.
Habits
Mimics are almost invariably hedonists due to their nature.
Mimics are born with an instinctive urge to grow, learn, absorb, copy, and experience. Not included with this is any sense of moderation, morals, or caution; those being only acquired traits by individual mimics. Mimics desire to experience, change, and expand their repertoire often pushes them to extremes.
Mimics are known to society at large as pests, and a criminal element. Their shapeshifting and extremist habits makes them predisposed to avoiding pesky things like 'paying for stuff' and 'respecting property', and even non magically adept mimics are capable of spitting acid and causing property damage and burn scars to law enforcement. They are nigh impossible to chain or cuff.
Mimics often store small items inside of their bodies in tiny bubble pockets to protect them from acid as a reflexive hoarding measure. Killing a rogue mimic is often followed by getting a solid tool or their own weapon to root about inside for valuables.
Mimics are capable of becoming sin mages, and if anything, given their origins in Esshar, are predisposed to such a curse.
