Generic, Text: Sword Dancer (Kobold Press)

Sword-dancers blur the line between warrior and courtier. The first sword-dancers hailed from the sultan’s court in the city of Siwal in the Southlands. Sword-dancers are graceful and charming, with wits as sharp as their flashing blades. Fighters who follow the sword-dancer archetype often attach themselves to powerful lords as bodyguards, spies, and diplomats.
