We could scarcely believe it when we saw the first wooden corner rising from the sand, and once we had the chests out and cleaned, we recognised the motif carved into each of them. The grinning skull; the Captains' Cohort.

The Cohort is believed to be the secret sigil that the great pirate captains used between themselves to mark important agreements or collaborations. The information or items marked so were sacrosanct. Unbreakable contracts. Priceless treasures. No ordinary pirate could mess with them, and if a captain did so, he would be punished, swiftly and fatally, by the Pirate King.

Well, that kind of thing is definitely above our pay grade. So, we're letting you have a go at getting into them. A team of intrepid adventurers such as yourselves are not likely to be phased by the old stories of sea witch curses or kraken assassinations linked to the Cohort. Or, you'll be too full of good rum and rations to care! You can keep the treasure - we'd just like the chests back after you're done. They must be worth a few bob too!
