Fire and Sword
A fantasy RPG system created by Raymond Turney. Raymond was a co-creator of RuneQuest, and Fire and Sword is his evolution of the system. It thus has much in common with BRP, but contains many new interesting mechanisms.
The system is released under the FreeArt License.
The 4th edition adds some rules for gaining POW, regaining magic points, etc. It also has a richer assortment of Virtue Points, Vice Points and Prowess points, to track a character's position in the world and accomplishments. There are also a few miscellaneous fixes, in including addition of the new item price table.
