"Natverse" is the unofficial title for an alternate-Earth created by Ringtail about an Earth where four species arose to civilization-founding status: The raccoonoid Procyonis native to the Americas, the wolf/fox-like Canisite from Europe, The tiger-based
Felini of Asia, and the humans of Africa and the Middle East. Unlike most alt-earths, the "Natverse" attempts to take culture, ancestral species traits, specism, and other sociological factors into the state of the world.
