Temple of Reflection

From publisher blurb: Mini-Dungeon adventure for 4 characters of level 12 The magical security expert Ytrellia De’bouchar had the reputation of a mad genius, so nobody was particularly surprised when she succumbed to the occupational hazard of paranoia and vanished. Known for her overly complicated but efficient security systems, her erstwhile patrons want to find her and help her recover. One of her last completed vaults, referenced as the “Temple of Reflection” in her sparse remaining design documents, might hold a clue to her whereabouts. The party must figure out how the notoriously-lethal complex works and document it—every mechanism might be a concealed hint!
