Maw of Shu'ma

The Maw of Shu'ma is the monstrous maw of Shu'ma found in the Dragon Soul and is host to acidic spawns. Yor'sahj the Unsleeping is found within, commanding the faceless ones in their assault against Wyrmrest Temple and binds the blood of the ancient horror to his will.

During the testing on the PTR, this maw was known as the Maw of Ruin and along with the Maw of Unmaking would explain the third maw's name (Maw of Destruction) and why it did not receive a more notable name, since players do not visit that one.
