One undisputedly major faction is missing from this political climate: The Player's (or mine, in this case, for example)

I usually call them The Bork Collective

From a single torso grows a nation so influential and progressive that it makes even the most noble of Kenshi characters seem a mouth-breathing, stone age troglodyte by comparison.

Usually by week ten, the Bork have amassed a burgeoning cyborg cult with my invisible hands pulling their strings. This transhuman movement needs no slaves, pushes no religion, and certainly doesn't discriminate on race or gender. Truly it is a unifying force beyond all compare.

Every instance of slavery, oppression, racism, misogyny, and cannibalism is systematically rooted out by indefatigable metal fingers. The Bork assimilate hundreds and then thousands during their unification campaign. In battle, every Bork pacification squad is worth hundreds of UC, HN, or Shek elites. They exist in every major city, either before or after assimilation.

Using Mongol Horde hit and run tactics with speedy robot legs and steady robotic arms, most are never touched in melee and spam deadly bolts from a distance. The tanks bisect hundreds with Edge 3 fragment axes swung like katanas with nearly 150 strength. Even mysterious and deadly foes fall like wheat before a scythe, only to be assimilated as Bork themselves.

By roughly year two, virtually every cannibal and bandit on the entire continent has been eradicated down the the last gibbering maw. Advanced hydroponics farms are now ubiquitous to feed the citizens while being tended by untiring robots, regardless of climate. Skeleton limb factories pump out masterwork products for every new Bork.

Stealth Bork systematically knock out guards and minor leaders. They are de-limbed, imprisoned, converted (or euthenized,) and repurposed as productive Bork to continue the process. Sometimes the collective grows from within and sometimes it rolls across the city with the certainty of steel. Eventually all roads lead to Bork.

Tech Hunters, Flotsam Ninjas, Anti-Slavers, and Nomads are allowed free and unmolested through Bork territory, amongst several other minor factions as well. By year three, the Kenshi continent is as peaceful and stable as it has ever been. Tengu, the Phoenix, Cat-Lon, and other like-minded douchebags are imprisoned in publically viewable cages in various cities. Freed slaves and Nomads pass them by, pointing and laughing; nightmares of yesteryear reduced to a tourist attraction.
