“'What is it?' hissed Conina. 'It's just The Luggage,' said Rincewind wearily 'Does it belong to you?' 'Not really. Sort of.' 'Is it dangerous?' The Luggage shuffled round to stare at her again. 'There's two schools of thought about that,' said Rincewind. 'There's some people who say it's dangerous, and others who say it's very dangerous. What do you think?' The Luggage raised it's lid a fraction. The Luggage was made from the wood of the sapient peartree, a plant so magical that it had nearly died out on the Disc and survived only in one or two places; it was a sort of rosebay willowherb, only instead of bomb sprouts it sprouted in areas that had seen vast expenditures of magic. Wizards' staves were traditionally made of it, so was the Luggage. Among the Luggage's magical qualities was a fairly simple and direct one: it would follow it's adopted owner anywhere. Not anywhere in any particular set of dimensions, or country, or universe, or lifetime. Anywhere. It was about as easy to shake off as a head cold and considerably more unpleasant. The Luggage was also extremely protective of it's owner. It would be hard to describe it's attitude to the rest of creation, but one could start with the phrase 'bloody-minded malevolence' and work up from there. Conina stared at the lid. It looked very much like a mouth. 'I think I'd vote for "Terminally Dangerous",'she said. 'It likes crisps,' volunteered Rincewind, and then added, 'Well, that's a bit strong. It eats crisps.' 'What about people?' 'Oh, and people. About fifteen so far. I think.' 'Were they good or bad?' 'Just dead, I think. It also does your laundry for you, you put your clothes in and they come out washed an ironed.' 'And covered in blood?' 'You know, that's the funny thing,' said Rincewind. 'The funny thing?' repeated Conina, her eyes not leaving the Luggage. 'Yes because, you see, the inside isn't always the same, it's sort of multidimensional, and-' 'How does it feel about women?' 'Oh it's not choosey. It ate a book of spells last year. Sulked for three days then spat it out.' 'It's horrible,' said Conina, and backed away. 'Oh yes,' said Rincewind. 'absolutely.' 'I mean the way it stares.' 'It's very good at it, isn't it?'”
