Sterns Yennich was a private and a GeNode, and for a brief time, a stormtrooper. A member of Janzor's platoon, at the start of the Imperial occupation of Kashyyyk, he was dispatched to the surface. Yennich, Wayson Dower, and Milo Strander were the only Stormtroopers to survive the battle and they fled within a tree. There, he was impaled and dragged underground by an immense spider. He was the last casualty of the battle.
