the Drowned Sacellum is a submerged shrine located in a cavern within Blackfathom Deeps. The ruined sacellum lies in a pool of saltwater and is partially overgrown with starfish. Murlocs and makrura live side by side in the area, thriving in the wet, gloomy environment. Like most of Blackfathom, the cavern ceiling is littered with thick tree roots, where dark wisps provide an eerie illumination.
The Drowned Sacellum is the first room players reach after the instance portal of Blackfathom Deeps. Access to the Pool of Ask'ar is gained by jumping across the ruined surface of the sacellum, which some players find difficult.
