Like Toon world, Narrative world is a place with looser laws of physics, but all in the service of telling a good story. From towns were people can sing like the chorus in a play to spring brake romances out of control. With a bit of effort one can do things that are imposable even in Toon World, but only if it would serve the story. Here one can live out a fantasy of being a super hero or super villain or have a soap opra style romance.
The history is hard to pin down as even that can change as needed, it seems to have all ways offered a mix or crossing of cultures. Some have even suggested it was a vacation spot of the gods. Myth/ fantasy mix with the modern in strange ways. Like mountain communities that now have local skyers, snowboarders and snow bunnies. A tavern might serve pizza, wings and have an arcade area. Multipole islands clam to be Atlantis. An Egyptian, Greek, Roman, Viking, Arabic, Indian, even a Asian one, even modern versions like English, French, German, Dutch, Rushin. Ruins of former concepts lie between active towns. Lost ideas of the past or future have appeared.
Role reverse realms exist like animals own humans, male things with a female twist and other way around. Kid stories with adult twists. Even were people take on the role of the other sex, like men giving birth and a being house wife or boys playing with dolls as girls play with action figures. Even ideas of equality play out. Modern ways of telling stories used by mythic/ fantasy beings.
