The Kech Shaarat, led by Ruus Dhakaan, are one of the clans of Darguun remaining faithful to the ways of their Dhakaani ancestors. Among the other Heirs of Dhakaan clans, the Kech Shaarat, or Bladebearers, are known for their possession of the Sword of the True King, a mighty artifact leftover from their ancient empire. 
Bladebearer soldiers brand sword-shaped marks onto one or both of their forearms.
