Duros is a level 60 elite wolf found in Alterac Valley.
Background
The Frostwolf wolves Duros and Drakan guard Drek'thar, clan leader of the Frostwolf Clan. The wolves are most likely named after former Frostwolf chieftain Durotan, father of Thrall, and Draka, Thrall's mother and Durotan's wife, who were both slain by Gul'dan when returning to the southern lands to talk to Orgrim Doomhammer.
