I have copied most of the pamphlet I provide to my players and released it here as the High Seas System Reference Document. This is partially for the curious, and partially so I can point my players to it for reference when they're not proximate to me or when I don't have the pamphlet.
You may notice that it's a little light on certain kinds of information. This is because if I'm using something WotC created, it's not legal to distribute it unless it's covered under the d20 SRD. This is perhaps particularly noticeable in the Religion section, where I provide a list of the deities I'm using, how they relate to the world, and what book to consult to find them, because no deities are in the d20 SRD.
