"I was born of hate, from my father's own seed. All it does is fuel me." When he wasn't surrounded by it, when he was calm he was very tame. It was why he'd become an arbitrator for Zeus. He was Braireos the Vigorous. He was the original thunderer. "The original storm giant before Olympians took over."
He was different now, having to mellow out to get through day to day life in a world that scarcely remembered his name. He stopped, wiping away the little pricks of blood that had accumulated. He wiped it off nearly complete with his masterpiece. He didn't see it as art, it was just a way to connect.
