Simulacrum

This realm of shadow and nightmares is a dark reflection of the material world. Said to be created by Mim and used as her workshop for horrors and twisted creations, the realm is ruled by one of her highest officers, the dreaded Nightmare King. This evil entity hopes to gain power over Temporis through the invasion of mortals' sleep, and it is both in twisted dreams and in the places the light never touches that the Simulacrum intersects with the material plane.
