The Scourge of the Weak was a league sky ship owned by Ilmus Pentephraxis. He was interested in exploring secrets of the termagantation of the termagant trogs, but Quint rescued Maugin from him. When Ilmus pursued the Galerider, her new-found skills as a stone pilot saved her and the Scourge of the Weak was destroyed. This event was mentioned in The Lost Barkscrolls.
