Despite their bestial appearance resembling gorillas, Metasimians are not "weregorillas" like some think. In fact, referring to them as apes is a great insult. Metasimians usually have black fur, but grey and brown variations are known to exist. Those few born with white fur are considered to be blessed by the Metasimian god Orang Pendek.
Metasimians originate from the humid jungles of the Mistlands in the continent of Mistaria. Most of them live in primitive tribes, but they are surprisingly intelligent, adapting to life outside their forest fairly quickly. They live somewhat longer than humans on average.
