Ceyrin is Circe's adopted older brother. He's the friendly one of their duo, usually taking the lead when Circe is being stubborn and protective of him. He cares deeply for his sister, which is why he worries so much about her putting so much pressure on herself. Her arcane studies are impressive, but slightly concerning considering she's rather small to be handling such power.

Ceyrin often seems more grown up than Circe, which is mostly true, but he can have quite the childish streak when he's exposed to other Eternally Youthful dragons and the hatchlings at the nesting grounds. He's quick to make friends and his cheerful attitude often brings a smile to many.

Ceyrin's kind disposition was what led him to make one of his closest friends, Nayda. Nayda is clingy, to say the least, after secluding themselves for so long and being isolated for most of their life. Nayda and Circe clash often due to both of them being overly protective of Ceyrin, despite him being the oldest. Nayda is younger than the sibling duo and does not talk much, but they are with the pair so often that others in the guild claim Nayda is merely the third sibling. Circe does not appreciate such rumors.

Ceyrin doesn't mind Nayda's attachment and does his best to help Nayda feel better when they try to shut down. He also takes care of his sister, urging her to relax and take a breath when she becomes too worked up. Sometimes, it seems like a lot for one little Gaoler, but Ceyrin wouldn't give up his family for anything in the world. He has the patience of a saint, most say.
