Zeth'Gor is a former Horde city in the mountains of southeastern Hellfire Peninsula. It is now overrun with fel orcs of the Bleeding Hollow clan. There is also fel orc called Warlord Morkh inside. When you slay him, a huge, green eye (Broggok) spawns and promises to meet you in Hellfire Citadel. Zeth'kur in Warcraft II bears a similar name and location; however, there is no evidence showing that they are the same location.
