I'm working on a story, that involves shapeshifters, humans, and the Seelie/UnSeelie courts. Takes place in the relative future...

I am hunting information on shape shifters - not just weres, but selkies, swanmays (I know, so D&D), any creature in legend that was known to alter shape from one (animal) to another (human).

Cross posting to a few places.
