Biography
While patrolling, Zake came across the Fourth Doctor and waited for orders. Styre's robot disrupted his vigil and he was forced to flee. To get away, he tried to climb down a crevice, but slipped and broke his neck. Having heard his scream, the Doctor went to the scene and when Zake's team arrived, was blamed for his death.
