Last Prison

The Last Prison (also referred to as the circle of stars) is a titan facility where the ancient mechanism that kept the Old God N'Zoth imprisoned is found. It is located close to the Eternal Palace.

During the Alliance and Horde attack to Queen Azshara's palace, the two groups teleported to the Last Prison and fought her, eventually defeating the naga queen. Azshara, however, managed to activate the titan device using the Heart of Azeroth, finally freeing the God of the Deep after millennia of imprisonment.

• The Raid Finder lists the last wing of the raid (which also includes the fight against Za'qul) as "The Circle of Stars".
