He was born in a very wealthy family but he was always attracted by beautiful things and what money couldn't buy, he took. He is a collectionner and doesn't do much of his days but contemplating his own posessions and hosting parties. He counts many friends, actually he counts no enemies: he can steal from anyone, friends included, regardless of the identity of one. He can find interest in anything, from the rarest diamond to the pink tiny seashell you picked up at the beach on your last holidays. He loves taking little tokens from each place he visits, from each person he meets, with a charming smile.
He is an extravagant player, young but very smart and really, no matter how he got any of his posessions, he loves to show them. His self-love can make him appear very obnoxious to everyone. He claims he can't love and one would be crazy to believe he could ever love anyone but himself but he is a fine fan of challenges. Just like he steals objects, he will be more inclined to want relationships with people who aren't free to be loved, either taken or uninterested in someone like him.
He loves his loneliness and thus, he won't be clingy in a couple, he might not even be loyal, he will hardly ever want to be in a couple. To get what one wants from him, people need to trade, always.
He can be cold or very teasing, his mood can swing just too easily but once he has his eyes on a prize, he's a cunning actor.
