i think both Elsweyr and the Black Marsh would be a good setting as they havnt be explored since Arena and it would be nice to see where the 2 beast race live.However since there all on the sourthen Edge of Tamriel Those plus Valenwood and Summerset would rock(i just dont want morrowind Skyrim or cyrodiil i could just play those there easy to find arena isnt as u need a DOS emulater)
