I like it! You've really thought this out.

Hmm, still not sure which faerie archetype to go with. I'm drawn to either stone or psychic, or something like shadow faerie (teleport through shadows, create temporary doubles of themselves from their shadow, etc). That or a character inspired by the Cait Sith, so enhanced agility/senses, can partially shapeshift to gain feline traits such as claws... I create so many kitty characters it's predictable though xD
