Is there no more impossible rotation than to roll in one's grave? Were the artifacts here not in fact eldritch and terrifying, this would resemble nothing so much as a seasonal Halloween store. It seems to function as a repository for such knicknacks, or perhaps a quarantine, but also presently serves (perhaps ill-advisedly) as a room for raising a familiar. The familiars are weirdly resilient to the dark energies of the artifacts, like chickens raised in nuclear fallout, so perhaps in time the familiars will in fact rehabilitate the cursed items stored here.
