Muātu is a character in Seeker, Slayer, Survivor.
A faithful and particularly determined aumaua from the island of Kazuwari, Muatu volunteered to have his head chopped off and shipped to the Watcher, in order to deliver a plea for help. He's not concerned by his fate or the grisly method of delivering a message. His only point of concern is ensuring that the Watcher actually helps, so that his death wasn't in vain.
- The Proving: Muatu's head and the spirit channeled through it start the quest, setting the DLC in motion.
