Death (Discworld)

The Discworld books with Death as a leading character, starting with "Mort" in 1987, are:

Rincewind began to say her name in "The Colour of Magic" but was cut short; since it began with "L", and in the audiobook version he pronounces "Lu" with a short u (), along with all the other aforementioned clues and traits, it is commonly assumed she is Lady Luck. (This would seem to jibe with a commonly-held superstition among gamblers that if they talk about their luck it will desert them.) Given Pratchett's fondness for setting things in opposition it might also be appropriate to refer to her as "Fortune," the opposite of Fate – he cannot be cheated, but she cannot be beaten. The one time Fate loses a contest with a mortal, it is with Cohen the Barbarian, another of the Lady's special favorites (she uses him as a pawn in an earlier novel) and he almost certainly has her aid in doing it. (Incidentally, Cohen wins in the same way as The Lady did in "The Colour of Magic"—rolling a seven on a six-sided die—although Cohen's means were rather less magical.)
