The Bākiraka is a clan of assassins within the Kushan empire led by Silat. They have fallen out of favor with Emperor Ganishka for unspecified transgressions and currently endeavor to regain his good faith through service against Midland and the other allied nations under the Holy See Religious Order. The best of the Bākiraka clansmen are trained in a lethal form of martial arts in which their skin is hard as rock and their knuckles can break both armour and bone. Rakshas refers to them as the Tapasa.
