Treasure map is an item found in the Message in a bottle on The Islands That Once Were Turtles. Talking to Quartermaster Gully with this item in inventory allows the player to travel to the previously uncharted island of Eisetes Cretor where players can talk to Azalea Oakheart to receive one taijitu.
The message in a bottle that contains this treasure map was last visible 6 days ago on 14 August. It will be visible again in 1 day on 21 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.
Fellow adventurers, a call for aid! I appear to be stranded, and my old bird, Electra, has bought the big one.-Azalea Oakheart, gnome pilot extraordinaire!
