Sezom
From Tardis Wiki, the free Doctor Who reference
Sezom was a native of Crinoth who aided the Nimon in coming to his world. Years later, in regret over having done so, 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, also providing 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. (DW: The Horns of Nimon)
