The plot of the adaptation largely follows the first two Discworld novels, The Colour of Magic and The Light Fantastic. The story follows the exploits of Rincewind, a wizard who is expelled from Unseen University after spending 40 years failing to learn even the most basic magic. In fact, Rincewind s head holds one of the eight spells from the Octavo, the most powerful spellbook in the Discworld, and he has been unable to learn others because they were afraid to be in the same head as the Octavo spell. Rincewind is forced to act as a local guide for Twoflower, a property insurance salesman and the Discworld s first tourist, who is visiting Ankh Morpork, and Twoflower s luggage, which is made from sapient pearwood and can run on its own legs.
