A cult stronghold buried deep beneath the city, from Agents of Edgewatch . Two levels connected by long cavern passages and an underground lake — this is a real dungeon crawl, not a single set-piece room.

Lower Level — A built stone complex sits isolated at the top of a sprawling cave system: cramped rooms holding a bloodstained altar and storage, linked by narrow winding corridors. Beyond it, natural tunnels wind past lava veins, a glowing rune circle, and out to a wide underground lake. Long stretches of cave connect everything, so travel time and ambushes matter here.

Upper Level — More structured stonework: a bloodied prison cell block, a circular ritual chamber with a body laid out at its centre, a hexagonal room, and rows of coffin-like alcoves near the southern end. Multiple distinct chambers link through winding passages, giving plenty of choke points and reveal moments for a slow crawl toward whatever's running this place.
