Seth is the son of Hades, the god of the underworld, his mother is Persephone. Seth spent most of his life around death and destruction, so it was only fitting that he was the god of death and destruction. When he turned eighteen Hades couldn't control him anymore, since Seth's powers fully developed. He wanted to go to earth, to not be in the deathly kingdom of the underworld for another minute. He left, he went to earth and he was immediately a troublemaker, he was a sociopath. He killed people, he destroyed things, he was like a hurricane, he destroyed everything in his path. He realized that earth didn't have many people on it anymore, it must've been his fathers work. He found some people though, they were called grounders, they split themselves up into clans and he admired that about them, he decided he wanted to be some kind of leader and since he was a god he didn't have anything holding him back, he took down the king of Azgeda named Roan and became the new king, he's not afraid to show his powers and he already has before. He's very open about being a god and he loves chaos, he causes it more often then not. He's still very merciless and he is insane, he is the god of death and destruction after all. he will kill anyone that gets in his way, he's a sociopath with a need for chaos, it's the only thing he knows.
