20K is an interesting story of persistance, and looks to be a fairly recent development. The outpost was started by Milo Chatter and was heavily besieged by Mutants and other monsters before he requested the aid of Omni-Tek who helped to clear the area. This allowed the outpost to service more of the small towns and camps in the area without major fear of being overrun. 20k shares many similar characteristics to Harrys in terms of their relationship with Omni-Tek.
