An abberation was a type of creature that had no place in the natural order of the Material Realm. These beings defied natural laws, with twisted forms and minds that harbored alien intellects and unfathomable desires. Abberations had bizarre and grotesque anatomies; they often possessed a multitude of eyes, tentacles, or other unnatural appendages, their forms shifting and warping in ways that defied logic. Their flesh ranged from slimy and translucent to hard and chitinous, and for some could change form or pulse with an eerie inner light.
Aberrations typically inhabited places where the fabric of reality was thin, such as ancient ruins, deep caverns, and areas tainted by dark magic or eldritch energies. They were drawn to sites of great arcane power or cosmic significance, where they could further their inscrutable agendas.
