fter the wizard Rincewind has fallen from the edge of the Discworld, the Octavo magic book saves his life and he lands back onto the world. Meanwhile, the wizards of Ankh-Morpork discover from Death that the Discworld will soon be destroyed by a huge red star unless the eight spells of the Octavo are read: the most powerful spells in existence, one of which hides in Rincewind's head. Consequently, several orders of wizards try to capture Rincewind, led by Trymon, a former classmate of Rincewind's, who wishes to obtain the power of the spells for himself.
