Apollo- Accused of high treason

Apollo may look like a mere silly child, and at times he can be quite immature, but behind that mask is a destroyed soul, confused and wondering why it is still here. He used to sing for the royal family, and it became sort of a daily lullaby for Princess Athena when she was a baby. But when the rehunga returned, Apollo stopped and fled the realm of fire and water in fear of having to fight and destroy her again. Though, he didn't get very far before the rehunga leaped into the king's body after the death of the queen and sent guards after him. When Apollo tries to explain the king is being possessed by the rehunga, no one listens to, therefor, the two countries of water and fire get worse and worse. After about eight years in prison for high treason, Apollo gets a visit from the water spirit and the fire spirit. About a year after that, Princess Athena, Blaze, and Mizu Freildwood. Will he help them destroy the Rehunga? Will he side with the rehunga after realizing why he couldn't fight her again? Or will he stay in the prison and rot?
