Sezom

Sezom was a native of Crinoth who aided the Nimon in coming to his world, believing their offers of technology advances to ensure peace and progress until it was too late. Years later, regretting his role in the Nimon's advances and now apparently the last survivor of his world, he gave information about the Nimon to Romana after she was transported to Crinoth. He helped her escape back to Skonnos to warn them about the Nimons' true nature. He also provided her with jacenite, a rare mineral that, when added to his staff, allowed him to stun the Nimon. While Romana activated the capsule to take her back to Skonnos, he was shot and killed by a Nimon while buying Romana time to escape. (TV: The Horns of Nimon)
