Serthrek'nish is a mythologial Scotti demon, said to small children and steal souls. Malcolm, assuming the guise of the sorcerer Malkallam, pretended to be warding off Serthrek'nish in Grimsdell Forest in order to break down General MacHaddish's confidence. MacHaddish, like all Scotti, was deathly afraid of the demon, and broke after Malcolm threatened to give him to the demon. MacHaddish then revealed the details of the Scotti plan to invade the Norgate Fief.
