The Archive - You are a museum or warehouse that was originally used to store the relics of antiquity. You are comprised of a vast series of large and small storage rooms filled with ancient scrolls, forbidden tomes, cursed possessions, ill-gotten holy relics, haunted objects, appropriated cultural artifacts, and other mysterious paraphernalia that were stored in your dungeon at one time or another and perhaps eventually led to your awakening with their various auras and energies. Perhaps you might occasionally find a useful one-use item or piece of forgotten knowledge amongst the mostly now-useless bits of dross and detritus.
