Description

The Discworld exists at a point near the very edge of the universe's reality spectrum. From here, the fabric of reality is gossamer and 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 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 universes attach themselves tangentially to the Discworld, 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. The Dark Desert is a region that, according to the Omnian religion, souls cross to pass into the next world.

Death frequently takes souls here, and in recent books, it seems to have become the afterlife of choice for most Discworlders, not just Omnians. The Disc also has a Hell, similar to that described by Dante, (though rather than "Abandon Hope, All Ye Who Enter Here", the sign above its gates reads "You Don't Have To Be Damned To Work Here, But It Helps!!!") and, like Milton's Hell, its capital is Pandaemonium. Various Underworlds have also been glimpsed, similar to Hades or Annwn. Another universe connected to the Disc is Roundworld (our own universe), initially created by the wizards of the Unseen University as a zone where the laws of magic did not apply. L-Space, a dimension that connects every library and book depository in the universe, is a natural outgrowth of the fact that "knowledge=power=energy=matter=mass" and mass warps space, and therefore, libraries are a very dangerous place indeed for the unprepared.
