King Triton

King Triton is the aging but powerful ruler of Atlantica. He had long white hair and a beard to match, and is very majestic-looking. He carries the Trident which contains undescribable powers. He is the father of Ariel, who he deeply cares for, despite the fact he shows it through a stone heart. The Trident can be used to activate the world's Keyhole.
