The music while exploring the realm is the same as the Temple of Light music in Fable and the Menu for Fable II.
Cartographilia links to the realm, as cartography is the study and practice of making maps and "philia" is the Greek for "love" - a love of making maps, which links to the map of the Sanctuary, which this realm is styled from.
According to a post by the Lionhead developer 'Lionbum' on The Dead Hamster, the original design for this Demon Door was one inspired by the game Minecraft. However, the map was extremely difficult to build, and was replaced by the much-easier version that can be seen.
The name of the place could also reference the Halo level The Silent Cartographer (the original Halo Demo level). The sky in Cartographilia is the same as the sky in Halo's Silent Cartographer, only instead of being inside a ring you are under the ring of a lens.
