Eisetes Cretor 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 northernmost tip of the fortress island of the Islands That Once Were Turtles, which can be investigated to receive a treasure map.
The message in a bottle to locate this island was last visible 6 days ago on 9 August. It will be visible again in 1 day on 16 August. (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 to travel and the player will be asked if they agree to travel to the uncharted isle.
- The name of the island is gnomish for "Me and a Bucket", according to the Translation book.
