Guthor

Orc warrior who accompanied Durotan on his assult on Telmor. After the battle was over the Horde had begun 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.

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