Background from Wookiepedia, the Star Wars Wiki.

The sect focused heavily on control; mixing meditative techniques and martial arts in a primitive yet potent form. The Force flowed through their bodies, allowing them to strike unarmed with expert precision and incredible power; a master of the art was able to far surpass unaided masters of martial arts such as Echani and Teräs Käsi, though most Force warriors learned various martial arts styles to further enhance their control and skill.

Most Force warriors also developed potent defenses as part of their meditations; a danger sense that allowed them to instinctively dodge attacks and escape fatal blows. Despite their powers, most were not warlike in nature. Many among them sought physical and mental discipline rather than simply to become unstoppable fighting machines.

Force warriors were rare among the Jedi, especially considering the prestige and abilities offered by the use of a lightsaber. As its use grew, their numbers shrank, though far more of them were able to survive the Purge than their more obvious brethren.

Outside of the Jedi Order, occasional small schools or other self-taught Force-sensitive beings discovered the art of control on their own.
