[Lawtan]

(Essentially swamp humans 3 feet tall who waged war against tribes around Cape Cod according to mythology, and were strong enough to come to a stalemate against those tribe's gods...able to shapeshift and use the equivalent of Will-o-the-Wisps to capture and steal the souls of people...described like a cross between a goblin (hooked nose, clawed, and all) and a chimp...

That area is odd for Native Americans as far as mythology goes...they aren't Ojibwe (Great Spirit and all)...and they aren't Mississipian (Cherokee) or Abenaki (Western polytheistic tribes)...they are closer in myth to the Eskimos...but they are northeastern North America...
They also have a demonic child cannibal necromancer, who slew chieftains for food every night, and raised their skeletons to protect him...family didn't know for a long while...


...anywho...
