Roanauk Icemist is the leader of the taunka in Northrend. He is being imprisoned in the ruins of Icemist Village by the Scourge. The player aids him in the quest chain Strength of Icemist, where the player frees him. He is then found with other Taunka'le Refugees where the player offically inducts him into the Horde as the leader of the Horde taunka.
Roanauk is possibly a reference to the Roanoke Colony, the lost British colony on an island off the coast of North Carolina, and the nearby Native American tribe the colony was named after. This could possibly be a reference to the idea that taunka are a forgotten tribe of tauren that colonized Icemist Village in Northrend some time in the distant past.
