Bladesinger

The Bladesinger prestige class is comprised of elves who have blended art, swordplay, and arcane magic into a seamless whole. They use very discrete tactics and precise movement in battle to maintain a highly effective combat defense. Using a mixture of arcane and martial abilities, Bladesingers act as roving guardians of elven culture, seeking to promote elven ideals, and as protectors and champions of the elven community.

Bladesingers have a prominent place in the society of the elves of Faerûn, being renowned as heroes of the elven race, and welcomed in elven communities. Bladesingers are taught in a single master-apprentice tutelage system, with a master taking on a single apprentice to carry on the work of defending the Tel-Quessir ("The People" in the elven language) and promoting their principals and way of life.

Bladesong
The bladesong itself is an extremely demanding martial art, the epitome of elven mastery of the sword, taking decades to learn, and never taught to those not of elven blood. It is debatable weather non-elves would even be able to learn the art, both because of the great amount of time needed to master even the basics, and because a certain amount of elven grace may be required to use it effectively. The bladesong is a primarily defensive style of combat, with devastating strikes considered less important than a superior guard position. From this superior defensive posture magical attacks and spells may be used without fear of successful counter-attack, when performed by an elf fully proficient in the style. In addition to the violent purpose inherent to all martial arts, the bladesong is uniquely elven in the fact that the aesthetic components of the style are as important as it's martial efficacy, with its dance-like movements and the haunting whistling sounds produced by the sword blade cutting through the air being the source of the name bladesong.
