Aidan is the son of Braum and his mortal ex-wife Claire.
Aidan and his father Braum have always had a difficult relationship: Aidan is old enough to grasp some of details of what happened to split up his parents, and he had trouble forgiving Braum for it. After his Chrysalis, he is furious with his father for having lied to them about his "true self" for so long.
Aidan is currently travelling the world with his brother Gus, being chaperoned (and educated in the ways of Kithain society) by the Countess Weyer. He has apparently developed some skill in the Naming art.
