One of the worst particular Mujee to encounter, Gromlins use their psionic prowess to erase all positive sentiment tied to a person's entire bank of memories. Every memory they have comes either terrifying and depressing and often succumb to their new mental state. Evolved to feed off the chemicals created by extreme duress, they often dig out the adrenal medulla from their victims and can live on that up to a month. While entirely passive to physical encounters, the males are characterized by their larger and rounder head.
