Durotan

From WoW: IncGamers World of Warcraft Wiki

Chieftain of the Orc Frostwolf Clan. Assassinated by Rend and Maim, Blackhand the Destroyer's sons, when he opposed the Warlocks. Durotan had a son together with Draka, and as an infant he was there when his parents were murdered. The son was left for dead but a human named Blackmoore found the young Orc and took him to the fortress of Durnholde and named him Thrall.

Thrall later became the New Horde Warchief, and has named the lands surrounding the Orc capital Durotar in his fathers name.
