"Well first I died." Said causally because, well, she had. "Then an Archfey named the Green Knight resurrected me and, I don't really know the intricate details, but essentially imbued me with fae magic to make me what I am now." 'Dryad' was technically correct, but likely not in the way he assumed. She wasn't bound to a single tree - she was bound to a forest with odd magics that barely made sense on a good day.

And, apparently, that binding could be broken by... other fey and whatever Vaeros was.
