Die Prophezeiung [The Prophecy][Outdoor]

As your crew enjoys a rum in the harbor bar, you overhear the conversation of 4 notorious pirate captains at the next table, who have hidden their greatest treasures with riddles about a prophecy and each with a talisman in a secret place. While drunk, the treasure map fell out of the pocket of one of the guys. As real pirates, of course, you don't miss the chance to get hold of the gold yourself, preferably "quickly" before more buccaneers get wind of the matter.
