ARRRR! I am Bluebeard the terrible!
May the ghosts of fifteen sailors curse anyone who dares disturb the first half of my loot!
Noone but sailors or avid hikers can reach my loot!
Now solve my riddle:
Five big old siblings, close and silent, stand in a formation of a dice five.
Noone kan hurt them but time and water.
One of them has the secret!
