Celaris

Celaris is a shapeshifter, he can change into a myriad of dragon breeds and other creatures. He just has to know the exact anatomy of the being he wants to imitate, but he can only shapeshift into living beings. He also can't change his colors, he can dull them down or make them brighter, but he can't radically change them. He's able to slightly change the patterns and locations of his genes on his body, like slightly change their shapes, but he can't get rid of them or entirely change them.
He acquired his shapeshifting abilities through an enchantment, specifically an enchantment on his tertiary gene. Its lines span over the entirety of his body, allowing him to transform his whole body.
He has a very broad knowledge of the anatomy of dragon breeds, beastclans and animals. Tharrhon and him often come together to trade information, and Tharrhon likes looking through the complicated and extensive notes Celaris has of all his knowledge. Anytime any of the Siblings or Devianne come across bones Celaris doesn't have yet, or when they need some bones identified, they always know exactly who to come to.
While his knowledge would serve going into healing very well, he prefers to spend his days floating around the clan's territory, or traveling into other areas of Sornieth to gather more information and pull pranks on unassuming dragons.
