The Outskirts
Set in a hidden city that only small groups of people know how to access that's home to countless mystical creatures and people with magical abilities! It exists in the regular world but is hidden to the untrained eye- folks who know of it are able to freely travel there as they please and some choose to live there! It is much more lush and green than the regular world with much more natural/fantasy-esque architecture, they rely less on technology by choice though it's not nonexistent!
