Thwip was a big, fat male fox jailer for Vilaya in Althier. He and his mate Binta were in charge of the captured Dibbuns. He was so overweight, he had difficulty bowing to his ruler. He was known to be cruel and sadistic towards the prisoners, and was much hated for it. His mistreatment of the prisoners was such that at one point Vilaya herself threatened to punish him if he did not ease off, as she did not want her hostages killed. His primary weapon was a whip; this, according to Flandor, was how he got his name.
