From the introduction:
Welcome to a very different version of the Caribbean that you may know. Here, piracy is an ever-present facet of life. Mostly because it seems like everyone and their grandmother calls themselves one. Some are just weekend pirates or still carry badges from when they were Cabinboy Scouts.
The point is, there's a lot of piracy going on here. Pirate-themed attractions, a pirate-centric economy, hell, stick 'pirate' onto the end of most any form of government like 'anarcho-piracy' and you'll probably find a governor running on that platform against the pirate democrats. Thankfully it's a very silly sort of pirate-infested Caribbean. Things are actually quite relaxed here, despite the constant yet almost friendly exchanges of cannonfire and insults.
