Since I want Ariel as a D link, I guess my character will be a Merperson then. :lol

Well, there are humans in Ariel's world. If you wanted to stick with Merpeople though, I imagine they'd have to use magic to grow legs for travel on other worlds. Either that or learn how to permanently levitate. Alternatively, they could come from a different world entirely.
