The term is archaic, calling upon the ancient language of the magi, and those versed in the eldritch arts. In the more vulgar argot, terms such as scrying room and equally mundane names are bandied about. The fact that such limited terms are used to describe the proper mystic's psychomanteum demonstrates how little they actually know about what occurs within.
The follow string of Mirror-folk evolutions, Mihradhz, Mihrral, and Mihradamagus, are collectively known as The Mirr. They are all curious and slightly annoying, each in their own way. They advance through their lives by pestering the rare mortals who visit their plane.
There is a small and strange nature-worship cult that has dedicated itself to freeing vegetables. They appear usually in working pairs or trios, arriving to villages and towns separately and wearing the local garb. For some reason, they have taken to disguising themselves specifically as a scholar, a cooper, and a fisher. At night, they will sneak into backyards and side gardens, digging up household fruits and vegetables. They pile the pilfered plants into a cart and vanish in the night. While the townsfolk wake up to empty gardens, the cultists replant the fruits in the wild to let them be "free".
