Since the first novel, The Colour of Magic (1983), the series has expanded, spawning several related books and maps, five short stories, cartoon and theatre adaptations and even music inspired by the series. The first live action screen adaptation for television (Hogfather) was broadcast over Christmas 2006. Another one for the cinema (The Wee Free Men) is currently in development.
Nobby Nobbs is the kind of person who joins the army to loot corpses. It is said that there's a field-marshal's baton in every footman's knapsack; Nobby's Army kit generally consists of two warehouses, complete with said batons, other armies' uniforms, golden teeth, other petty valuables and several kilos of boots, some of them still occupied. Despite his kleptomania, he is honest about the big things (at least, the ones too big to steal) and is described as someone that you can trust with your life, although you'd be daft to trust him with half a dollar. Sgt Colon also remarked in Jingo that he had heard of places where the generals looked at which side's uniform Nobby wore at the moment to learn the situation of the battle.
He is described as untidy, smelly, and despite being human, about the same height as a dwarf, and carrying a certificate signed by the Patrician to prove that he's a human being. The text of this note can states that on the balance of probability, he is a human being. A running joke is the inability of others to believe this, despite — or even because of — the evidence. In fact, in Hogfather, even Death himself was unable to discern Nobby's species. He always seems to have a cigarette butt about him, normally stowed behind his ear, which has been described as a nicotine graveyard. Cigarettes quickly become butts in his presence, and stay as such for an apparently infinite amount of time.
The main character is Lewton, the Discworld's first and only private investigator, and former member of the Ankh-Morpork City Watch. His investigation of a brutal murder gets him involved in a sinister plot. The game's story line is a completely original creation, unlike the previous Discworld games, two of which were based on particular novels, and one of which was a mixture of elements from several. It is set in Ankh-Morpork, the largest city on the Discworld. Pratchett was consulted on the story and wrote some of the dialogue; he was credited in-game for causing "far too much interference." As it is a film noir parody, the game's protagonist Lewton frequently engages in hard-boiledsoliloquy, or monologue.
The game features many new characters and locales, which do not appear in the Discworld books. However, as the game is set in Ankh-Morpork, characters and locales from the books also appear, such as the Unseen University, the Dysk Theatre, Pseudopolis Yard, the City Watch and eccentric inventor Leonard da Quirm. The game's manual includes an introduction written by Discworld creator Terry Pratchett.
None of the characters created for the game have explicitly been introduced into the Discworld novels, although Neoldian, the blacksmith of the gods and forger of the Golden Falchion (a major plot element in the game) may be the unnamed blacksmith god who appears in The Last Hero.
He sagged to his knees. He ached all over. It wasn't just that his brain was writing cheques that his body couldn't cash. It had gone beyond that. Now his feet were borrowing money that his legs hadn't got, and his back muscles were looking for loose change under the sofa cushions.

William barely had time to undress and lie down before it was time to get up again.
-- The Truth
A chocolate you did not want to eat does not count as chocolate. This discovery is from the same branch of culinary physics that determined that food eaten while walking along contains no calories.

This man was so absent-mindedly clever that he could paint pictures that didn't just follow you around the room but went home with you and did the washing-up.

'Listen, Peaches, trickery is what humans are all about,' said the voice of Maurice. 'They're so keen on tricking one another all the time that they elect governments to do it for them.'

The Colour of Magic is the first Discworld novel, and was published in 1983. It is also one of only six Discworld novels to be divided into sections or chapters, the others being Pyramids, Going Postal, and the three books for young readers. Each chapter is in fact a separate short story featuring the same characters. The idea of The Colour of Magic - that all that happens is due to the gods' gambling - is somewhat similar to traditional role-playing games, in that the roll of the dice determines what happens to the characters.
