This is sorta based on an idea I had while watching empires smp
You were going about your day when you where suddenly teleported to a dimension where there exists strange and unique civilizations. these civilization are strange in that some seem be populated by non human sapient creatures and though some do have humans populating and occupying them these people have strange inhuman abilities. When try to talk to an occupant of one of these civilizations you find that they can perfect English and are very willing to let you join their civilization along with explaining. these civilizations were founded by visitors to this realm from earth a few years ago. These visitors created this very world using arcane magic and advance technology as a sort of very realistic roleplaying game where they each set out to make their own fantasy civilization but the tools they used to create this world were powerful then they realized and before they knew it they created kingdoms with completely sentient beings populating them. When the visitors realized what had happened they had decided to leave the world to its own devices. Though they had left their a glitch in how the world worked where it bring in new humans and only let them after they lived a few months in one of the kingdoms. Each kingdom has it own theme that said kingdoms architecture clothing and lifestyle themed after. The also control what powers and or physiology you get if your a citizen of that kingdoms. you only join one kingdom but still interact with occupants of other kingdoms. Once you join a kingdom you will slowly began to obtain the same powers the citizens have and even slowly begin to transform to match their unique physiology even your clothes and mannerism will began change to match the kingdom though you will keep your original personality and memories. After the few months are over you will returned home at the exact time you left with a all powers still with you and the ability to switch between earth and this dimension at will and even bring people from earth there and vice verse
