Castaways

Castaways are non-player characters that can be found in the Arc by finding a message in a bottle and using the treasure map contained in the bottle to locate the castaway. Progress of which castaways the player has found can be seen in the Arc Journal. Finding all the castaways unlocks the title.

Once a message in a bottle is found it will always be visible, unless the message in the bottle or its treasure map is in the player's bank or inventory.

Different bottles are available on different days, with the available bottles changing at daily reset (00:00 UTC) and the bottles appear on the same day for everyone.. Each bottle has a unique cycle, becoming visible once every few days; e.g. the Milky Bay bottle appears every day, while the Eisetes Cretor bottle appears every 7 days on Wednesday. For each bottle's cycle see the table below.
