The Observation Ring is a subzone of Ulduar. Auriaya resides within here. Players must defeat Auriaya in order to reach the Keepers of Ulduar: Thorim, Hodir, Freya, and Mimiron.
From the north, clockwise, the ring connects to the Conservatory of Life, the Clash of Thunder, the Halls of Winter, the Shattered Walkway, the Hall of Memories and the Corridors of Ingenuity. Players can also look down into the Prison of Yogg-Saron, beneath the shattered glass dome in the center of the ring.
