The Worker's Militia was formed when the Xeran Mining Corporation laid off all the workers and replaced them with HND-9 mining droids. The disgruntled workers started sabotaging the droids, which led the corporation to evict the miners from the company owned housing.
The Militia retaliated by reprogramming the droids to attack out-bound freighters that were hauling ore. The corporation then hired bounty hunters to hunt down the leaders of the Militia and put an end to the uprising.
