Airen might seem cold-hearted at first, but Zeraphine and Shawn change him for the better. Slowly, he opens up to them, as he goes from introvert to extrovert. He also has a form of separation stress because he got forced to kill and torture elves and humans when he was little. He got scared of the people that forced him to do so, so when he is alone, he shuts down.. He cares a lot for his friends, and is one of the main protagonists of the book. He is a spirit that killed Vivi. He is very strong and intelligent, and knows everything about mythical creatures.

He originally had black hair, but when he heard the screams of tortured persons and killed Vivi, his hair went white due to stress. It was then that he realized he had to escape the spirits.

You pronounce Airen as Ee-run.
