The kamen represented the most granular military unit of the Kaleesh war machine, the Kolkpravis, even existing before the formation of that military structure on Kalee. These kamens were comprised of anywhere from two to forty Kaleesh tribal fighters, with the most formidable warrior assuming leadership with the unofficial designation of blackarm. A grouping of one hundred kamens formed a larger unit called a horde, commanded by a Tarkhan.
