Moonshrine Ruins are located within Blackfathom Deeps and are the grounds of the Twilight's Hammer cult of this area. The ruins are partially submerged and the water churns with life, from crabs to threshadons.

Moonshrine Ruins lie beyond the long tunnel system past the Pool of Ask'ar and leads directly into Moonshrine Sanctum. Access to the Forgotten Pool can also be found here. Baron Aquanis is summonable through an underwater runestone beneath the ruins.
