I'm not sure. In any case, I originally started dreaming of Horseria as an open-source pony setting that's legally distinct from Hasbro's, but compatible with FiM universe. It's another continent that the ponies have started colonizing only about a generation or so ago, so if this setting was ever to be used for something commercial, the main continent the ponies came from is referred to simply as the maneland.
But relevant for this CYOA, it's a land of early settlement, a few bigger cities, and lots of unexplored lands and mysteries.
