Caller's Chamber
From WoWWiki
The Caller's Chamber is located inside Razorfen Downs, and is where the first boss of the dungeon (assuming the party heads left at the first fork), Tuten'kash, can be summoned using a gong. It lies past the chamber where Belnistrasz's quest 
[37] Scourge of the Downs ends, and leads through winding passages to the Murder Pens and the Bone Pile.
