Death (Discworld)
Death is a fictional character in Terry Pratchett's "Discworld" series and a parody of several other personifications of death. Like most Grim Reapers, he is a black-robed skeleton usually carrying a scythe. His jurisdiction is specifically the Discworld itself; he is only a part, or minion, of Azrael, the universal Death. He has been generally used by Pratchett to explore the problems of human existence, and has become more sympathetic throughout the series.
Discworld (world)
Great A'Tuin's gender is unknown to the inhabitants of Discworld (though in "The Colour of Magic" Pratchett describes the turtle as male), but the subject of much speculation by some of the Disc's finest scientific minds. The sex of the World Turtle is pivotal in proving or disproving a number of conflicting theories about the destination of Great A'Tuin's journey through the cosmos. If, as the Discworld version of the popular "Big Bang theory" states, Great A'Tuin is moving from the Birthplace to the Time of Mating, then at the point of mating the civilizations of the Disc might be crushed, simply slide off, or else the entire world will end. The hypothesis is that all stars in the sky are obviously also worlds carried by giant turtles, and that when all the turtles meet they will mate passionately, for the first and only time; from that mating, it is hypothesized that new turtles would be born to carry a new pattern of worlds. Attempts by telepaths to learn more about Great A'Tuin's intents have not met with much success, mainly because they did not realise that its brain functions are on such a slow timescale. All they've been able to discern is that the Great A'Tuin is looking forward to something.
