The Siren's Heart

The tale of the Siren's Heart is as old as the oceans themselves. Supposedly it's a gem of fine blue like the midday sky. The gem was hidden in ancient times by the Pirate Finch Riot. It's value should it be found in unprecedented. It is seen as symbol of status among pirates, if one was to find the Heart they surely would be better than all other pirates. Many pirates search for this gem endlessly but all who have tried have turned up dead or not turned up at all. Because of this most pirates believe the Siren's Heart to be cursed.
Some wonder if the Heart even exists. Maybe it simply a tall tale spread by Finch Riot, or maybe the cursed Heart is out there, waiting to be found.
