Christmas Island

Christmas Island is a hidden island in the Arc region of the Wushanko Isles. Traveling to the island requires finding a Message in a bottle in the Spirit Realm of Aminishi. The bottle is located on the beach below where the Aminishi moai rested and is revealed after talking to all four of the player's crew on each of the three main islands Waiko, Whale's Maw, and Aminishi after completion of the Jed Hunter miniquest. Investigating the bottle rewards a treasure map.

While carrying the map in the inventory, players can talk to Quartermaster Gully and will be asked if they agree to travel to the uncharted isle.

On the island, players can talk to Manti Claws, brother of Shanty Claws, to receive one taijitu.
