{OLD}
Nix is called something named a Mimic Notreil. He's a subcategory species of a random energy matter generated creature called a Notreil [naught-rah-eel], and his form was summoned with someone in mind. They are always subconsciously keeping their form together like a heart beat, yet sometimes their form can be disturbed and their minds can be opened and rearranged like a filing cabinet under the right circumstances.

A notreils form can go through different stages of instability and open different personality/instinctual traits and memories in some cases.
