Other Dimensions of The Discworld - Dungeon Dimensions

The Dungeon Dimensions are the endless wastelands outside of space and time.

The sad, mad things that live there (a pastiche of Lovecraftian horrors) have no understanding of the world, simply craving light and shape. Therefore, they try to warm themselves by the fires of reality. It has been noted that should they ever break through, the Universe would be destroyed, rather like an ocean warming itself around a candle. Some of them can survive in this world under special circumstances, and become something rather like demons (though they cannot be seen as demons per se, first because their existence is not dependent on human belief, and second because, as they are completely lacking in vitality, they are neither good nor evil, but the opposite of both). For most though, the reality they crave is soon fatal, due to their lack of a natural morphic field.

They are jealous of all things alive and so far as their emotions can be understood, they feel mostly hatred, stemming from that jealousy, of all 'real' creatures. They are lured by heavy concentrations of magic that thin reality and may allow them an easier point to break through. Sometimes they break through into a mind, using that being's mind and body to further their own ends. Magical minds shine like beacons to them. The number eight also seems to attract most of them (especially Bel Shamharoth, although this one might be less angry than the others as it has acquired physical existence, which, however, makes it easier for it to harm creatures) which is why wizards are advised to avoid saying it.

The prettier ones are said to resemble a cross between an octopus and a particularly angry bicycle. For a discussion of the named creatures from the Dungeon Dimensions, see Discworld gods.
