Death (Discworld)

The Discworld books with Death as a leading character, starting with "Mort" in 1987, are:
List of dimensions of the Discworld
Discworld, the fictional planet of a fantasy series by Terry Pratchett, exists at a point near the very edge of universe's reality spectrum. From here, the fabric of the fictional universe's reality is gossamer-thin, and excessive pushing can and often does break holes into other, often far less hospitable, domains. The most dangerous of these domains are the Dungeon Dimensions, a region beyond the narrative's reality itself, whose inhabitants (inspired by the formless horrors of H. P. Lovecraft) wait to swamp our reality with all the force "of an ocean warming itself against a candle". A number of minor fictional universes attach themselves tangentially to the Discworld universe, particularly Death's Domain, the home of the Disc's Grim Reaper, from which he descends to do his job, and the parasite universe of Fairyland, home of the sociopathic and vicious Elves. Additionally, the Dark Desert is a region that, according to the Discworld's Omnian religion, souls cross to pass into the next world. The Discworld character Death frequently takes souls here, and in recent books, it seems to have become the afterlife of choice for most Discworld characters, not just Omnians.
