After the presumed death of their long-absent father, Edred inherits the title of Lord Arden and moves with his sister Elfrida into the decrepit family castle where they find an ancient spell that conjures up the magical Mouldiwarp and, with his help, set off on a journey through time in search of the lost Arden treasure.
