I'm a mod over at Hou Tian, and Avatar the Last Airbender/Legend of Korra roleplaying forum, and I'm popping in to invite everyone to check out Hou Tian and join the fun; we accept original characters, and have a number of canon characters available for adoption.
We also have plenty of plottage to go around! The Gaang-verse has two distinct factions; The Jade Shark -a proto-Equalist Anti Bending movement- and The Original People of the Flame -a group of Fire Nation citizens looking to infiltrate Zuko's inner circle, restore the Fire Nation to its war-time glory and dominance, and take back control of the Colonies; now know as Republic City. The Krew Era has the White Lotus sentries, various gangs and organized crime (Triple Threat Triads, anyone?), and the growing threat of a Equalist Movement resurrection. Hou Tian also has Pro-Bending aplenty; the leagues, the competition, and a special game-mode for roleplaying matches.
If that doesn't strike your fancy, members are always free to pitch their own plot ideas!
