I've been want to post this for a while, and now I have an opportunity. I've thought up some names and ideas for some mentioned worlds in Wizard101 and Pirate101. So far I've only gotten two.
Jaki Whisperwind's homeworld- Ahwahnee, Native American world home to Jackrabbits, Kangaroo Rats, Roadrunners, Tortoises, and Gila Monsters. Would be a fourth arc world, possibly the level 190 world.
Unnamed Sloth World- Tiredclaw, Jungle-ish world near Azteca. Would be a dungeon zone for level +95 wizards.
