Monsters

An expression of uncontrolled life magic, the Monster race might be the most varied in Centralia, in size, shape, intelligence, behaviour and moral alignment. Monsters are a very, very weird race, present all across the world, who each have unique characteristics to the point that most Monsters look like entirely different species. The only things you can be assured of with a monster is that they're organic, they can breed with other monsters, and you'll never see another Monster like it. It's been posited by some that Monsters are Life Elementals, in the same way Ethereals are Space Elementals.

Magic
The magic of Monsters is the source of much interest and study amongst magical academia, as while all monsters are explicitly life elemental, almost all of them can tap into at least one other element. Monsters don't tend to learn magic, but simply have access to a few powerful spells they can cast on instinct. The Monster's passive usage of life magic is probably why they mutate so far from whatever the species' baseline is.
