Cosmos

Born with the colors of his father and the features of his mother, Cosmos is one of the most beautiful dragons ever born to that water clan. However Cosmos was headstrong, longing for the skies rather than the ocean home he was from. Thus, he set out for adventure after both his siblings did. However, Cosmos clearly didn't have much of a sense of direction, getting lost on the way to the air clans and ending up in the dense and dangerous forests up north. Fortunately for him, he landed near a lake where an ice spirit recognized his water heritage and helped guide him towards friends. The spirit took him to one of her oldest friends, another Skydancer, Perseus. He took one look at this lost hatchling, reminded of when he first left his water clan, and took the small hatchling in. His mate and him both were childless, and taking care of this young dragon was the perfect calling for Annabeth and Perseus.
