Guthor

Guthor was an orc warrior who accompanied Durotan on his assault on Telmor. After the battle was over, the Old Horde began to trash the city. Durotan quickly put a stop to the mayhem and ordered the city searched for supplies. He set up two groups to start on opposite ends and meet in the middle, one led by Orgrim, the other by Guthor.

His status afterwards is unknown.

Guthor of the Warsong?
It is possible Guthor was the Warsong representative for the war party, as mentioned a page prior.
