From publisher blurb: This adventure is for 4-6 heroes of 5th level, for a one-shot adventure for 5th Edition. (Though this may take 1-2 sessions to complete). The Fifth Spar takes criminals to an island prison quite often, and normally the crew and the guards can handle themselves. However, there are a number of high-priority prisoners on board this time, so the heroes are hired to provide extra security. And one night, during a storm, not only do pirates board the ship, but the prisoners break loose. Now it is up to the heroes to contain and stop them.
