Commander Zazzka was a Kastrian working from Outer Dome Six.
Biography
Zazzka took control of Eldrad's obliteration module after his colleague Technic Obarl froze to death from the solar winds ravaging Kastria. He detonated it on the orders of King Rokon.
Zazzka protested the order that it be activated at nineteen spans, instead of twenty-five where Eldrad would certainly not survive. Rokon explained that it was necessary as solar winds might result in a loss of control over the craft. Zazzka detonated the module as ordered and Eldrad survived, with his hand ending up falling to Earth. (TV: The Hand of Fear)
