Capital Gardens

Eldre'Thalas, now called Dire Maul, was built to keep Queen Azshara's arcane secrets, and its keepers, the Shen'dralar, outlived the Great Sundering. Starved of the Well of Eternity's power, their leader Prince Tortheldrin had five pylons raised to cage the demon Immol'thar, and his people drew on its energy to stay immortal.

Over the centuries the prison weakened. To keep his own power, Tortheldrin turned on his fellow Shen'dralar and drained them. The Capital Gardens, once the Highborne's park and court, now hold his last loyal followers, withered trees, angry ancients and the caged demon itself.
