Wandering Syndicate (Earth-5291)

The Terra Triad is an organized crime syndicate consisting solely of earthbender criminals active in the Land of Birds and the Land of Fire's Capital City since at least 123 AG.

History
For a long time, the Terra Triad wandered from land to land in seek of earthbending techniques to appropriate for themselves. At some point, one of their leaders, Hoki, decided they needed a permanent place to settle. Doing that, they went to the shinobi-less and thus mostly unprotected minor nation of the Land of Birds, where Hoki disguised himself as "Moso", becoming the chief adviser to the nation's Bird Lord Owashi, eventually assassinating him.
