Sway was once a standoffish male who didn't want anything to do with anyone. However, pups of his were brought to them, and he's joined the Realm of Light for help in raising them. They need a mother, however. He might be a bit reluctant at first, but once she gets to know him, whichever you think would be best, he wouldn't leave her. He's fiercely loyal to those he considers family and friends. Despite the way he acts, he's not at all hard to get along with.
