The Isles of the Sun is a d20 campaign setting with a nautical flavor. The Isles feature a victorianesque imperial society on the brink of major change and potential upheaval. This book gives GMs and players everything they need to adventure in the isles, including new races, prestige classes, spells, magic items, feats, detailed information about Isles society, and hundreds of years of history. Mixed into the guide are tidbits of GMing wisdom from the author’s over 20 years of GMing experience.
There is also a player’s guide to the setting, which contains a subset of the information in the full guide.
