I wish to keep Dwilight because of the unique nature of contient, and the rp atmosphere. I also like the size of Dwilight and the amount of different realms. I found a lot of the other continents to be too small for my liking.
Beluterra, because the invasion and magic concept seems cool, despite the massive damage caused to the lands.
Atamara, I'm kinda meh about, as well as Far East Island. I believe bringing sea travel would spice things up on these islands.
