Zephos (not to be confused with Xephos) is a level 80 Human Death-Knight on the Venture Co. server in World of Warcraft. His character page can be found here.

Judging by his equipped items and level, this character is only being used for Wrath of The Lich King content, and has not entered Cataclysm, let alone Mists of Pandaria content.

Zephos is played by Lewis Brindley of the Yogscast, and goes on many adventures with Honeybear.
