History
In his extra dimension Folding Halls, Halas placed many traps for curios looters. In his study, he arranged rows of cabinets with books, but some of them were mimics the Mighty Nein had to fight to find valuables.

Investigating the desapearances in Dreamscape Theater, the party exited in a seemingly unremarkable cul-de-sac alley next to the theater. However, Imogen and FCG, using their psoinic, sensed an odd presence. As the group continued to inspect the area, the striations of the stone wall in the back of the alley split, reaviling an eye, jagged spikes and tendrils of the mimic.
