Ephyr

When she first meets Ryu Han-Bin she assumes (correctly, but unfoundedly) that he was an Otherworlder and tries to take care of him, but ultimately Han-Bin's punch proves too much for her and she submits. She tells him her story: She once belonged to the Sky Dragon Knights Order of the Exrad Kingdom, but when the Prince attempted to ride her his abilities were insufficient which resulted in his death, the night responsiible for her was executed while she was barely able to escape.
