The Legend of the Shining Jewel is a campaing setting that allows players to play for free. Some of the core rules are found in this PDF and they are conveting old 3.5 mods into Pathfinder mods. This has been a slow process, but you can still play the mods with Pathfinder PC's, just you are hella overpowered. You can also play this setting at various Cons around the country and it has recieved high reviews from those who played in it. It is a living campaign, so you can take the character that you played at home with to the cons and be on equal footing with even the staff. I, as a player, highly recommend it.
