Sickear was a former searat who told Ferahgo the Assassin about an alleged badger treasure that was hidden inside Salamandastron. He was miserable and one of Ferahgo's most servile soldiers. Sickear was forced to tell the tale repeatedly to Ferahgo in secret, due to the weasel's insatiable greed.
Sickear was a lookout with Feadle in case Klitch and Goffa returned. He was pursuing Mara and Pikkle with Migroo and Dewnose, but they didn't catch two young ones. The Assassin tricked him into being killed by Forgrin and Raptail.
