Cashel was born in Cork.  He is an only child. His parents are distant because they don't understand him but he doesn't give an importance to what people think. He's pure-blood but he love muggle world. His mother is Irish and his father is English. He is excited about Hogwarts because he doesn't really love his house. He did magic the first time to fix his favorite book.

Cashel is an androgynous little boy. He likes when people confuse him with a girl, he finds it really funny. He is always ready to help others but he's also very alone. He is always closed in on himself. Convinced of being a wood elf, he presents himself as such. He plays the flute. He is asthmatic. It is difficult to know when something pleases him or not. He doesn't talk much, not because he is particularly shy, but simply because he doesn't think he has much to say. He doesn't really suffer from the rejection of others. He has blue eyes and brown air. His face is androgynous and it is complicated to determine his gender. He is used to wearing colored underwear according to his mood and the weather. He wears long gold and silver bracelets. He's afraid of the dark and the thunder. He likes animals like cats but he is allergic.
