The Luggage is a fictional object that appears in several of the Discworld novels by Terry Pratchett. It is a large chest made of sapient pearwood (a magical, intelligent plant which is nearly extinct, impervious to magic, and only grows in a few places outside the Agatean Empire, generally on sites of very old magic). It can produce hundreds of little legs protruding from its underside and can move very fast if the need arises. It has been described as “half suitcase, half homicidal maniac”.

Rincewind the Wizzard is a fictional character appearing in the Discworld novels of Terry Pratchett, several of which feature him as the central character. He is a failed student at the Unseen University for wizards in Ankh-Morpork, often described by scholars as "the magical equivalent to the number zero", and spends just about all of his time running away from various bands of people who want to kill him for various reasons. Rincewind is also reputed for being able to solve minor problems by turning them into major disasters. His unique "skill" is implied to be due to being the chosen one of "The Lady", the anthropomorphic personification of luck.

Unseen University’s motto: NUNC ID VIDES, NUNC NE VIDES (which would roughly translate as ”now you see it, now you don’t”)
