Agar Atoll is a hidden island in the Arc region of the Wushanko Isles. Travelling to the island requires finding a message in a bottle on the beach right next to the southern dock exit on Goshima. It can be investigated to receive a treasure map.
The message in a bottle to locate this island was last visible 2 days ago on 20 September. It will be visible again in 8 days on 30 September. (wrong?) Once a message in a bottle is found and when a player has walked near its spawn location when it was visible it will always be visible, unless the message in the bottle or its treasure map is in the player's bank or inventory.
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.
