Seraseeya was an unusual creature. With a foot in both worlds, she was neither human, nor fully a beast. Her mother was a harpy who had the unfortunate accident of picking a human male as a mate. We wont go into details, but the result was Seraseeya, and her 3 other sisters.
Things were not too bad to start. The Harpy Broodmothers could tell there was something a bit different about them, they had funny feet and they lacked claws on their hands. There was not a feather on their head, nor much hair to speak of. They let them be, thinking they would grow into their features.
As the years passed, it became apparent that there was indeed something wrong, they looked more human, than harpy. This would not do.
