Auchindoun is a former draenei holy site and Horde fortress in the middle of the Bone Wastes in Outland's Terokkar Forest. It was a hallowed ground until the Shadow Council took over, summoned an extremely powerful demon as old as time itself, and destroyed half of Terokkar Forest in the process. Different factions now vie for power in this magical spot: Ethereals suck the arcane energy from the Mana-Tombs, the Burning Legion harvests souls inside the Auchenai Crypts, arakkoa zealots work dark magic in the Sethekk Halls, and the Shadow Council plots its domination of Outland from within the Shadow Labyrinth.

Sethekk Halls is a wing of Auchindoun and its entrance is on the east side of the Ring of Observance. On heroic mode, it contains a boss which drops a coveted rare mount: Reins of the Raven Lord.
