Treasure Map is a mission that can be found in the Tavern's Side Room. It is an infrequent mission, appearing approximately every 25 days, though it will reamins available in the Side Room for around a week.
The map bearer offers you the first piece of a nine-piece treasure map. If you buy it, a treasure quest is started which you will have a few weeks to complete.
The Other Pieces
You can buy the other eight map pieces from Informers at various Taverns. An Informer with a treasure map piece charges considerably more than one with regular information. Starting at around 600 to 700 gold, the cost of map pieces rises for each new treasure quest.
It is not normally necessary to buy all nine pieces to deduce where the treasure is to be found. The central piece (with 'X' marking the spot) is a great help but not always essential.
To recover the treasure, you will need to sail a ship over the precise location of the 'X'. Treasure is typically worth from 15,000 to 25,000 .
