Bladedancers

Bladedancers are elite bodyguards for elven nobility.  Born into elf families funded by royalty, they undergo excruciating agility and perception training to perfectly parry their opponents attacks & strike back with incredible speed.  Those on duty have their hair dyed red & wear a thin golden crown to signify their position.  The Bladedancers teachings are well protected, being entrusted to a small minority of family leaders.  In addition, once they've learned what the Bladedancer is, they're forbidden from separating from their noble family or teaching their skills to outsiders.  Failure to comply will result in their execution.  Despite their scarcity & the protection over their teachings, it's not impossible for another race to become a Bladedancer.  They can be endorsed by someone close to them due to their skills,  learn from one of the few Bladedancer escapees, or steal the knowledge from a noble household.  Regardless of their origin, they are defensive masters, using two weapons to quickly cut down their foes.
