Grimm aren't animals. That has been made perfectly clear. They are an entirely different type of entity, which exist in a fictional world with no magic. There are therefore no spells. There is Dust, which is a psychoreactive mineral which exists in a known number of forms, and can be recomibined predictably in an pseudo-alchemical manner. There is Aura, which reflects an empirically-demonstrable metaphysics, as the soul is known to exist, and is quantified. What precisely it is is still an open questionparticularly in light of a synthetic intelligence which possesses one. The limits of Aura are very likely well-defined, and limited. There are also the Creatures of Grimm, which are mysterious entities which lack souls, and are attracted to negative emotion; they are unnatural, but not magical, since magic doesn't exist. They are not alive in any conventional sense; their immortality and decay processes are reflective of that, as well as the explicit lack of a soul. To our knowledge, these are the only unnatural elements involved in with the world. There exists nothing so formalized as a magic system.
