During the Mongh-Kiegh's so called "great crusade" a contingent of "Night Lords" were engaged and eventually captured by a gang in H.A.M.Y.'s employ. Upon their return these "Night Lords" escaped and caused the local gangs significant trouble. After their eventual extermination several gangs expressed regret at the loss of such stimulating opponents. In response H.A.M.Y. entombed the first of what would eventually become many un-augmented Mong-kiegh in the still functional suits and given "freedom" amongst the spires. Over time the process has been refined and the "hosts" now have the skills to operate their armor-tombs encoded in their minds which is slowly added to and overwritten by a gestalt consciousness housed in each suit. This repeated and unending forced life has resulted in the gestalts bonding emotionally, going quite insane, and becoming almost as cruel as their nominal captors. Almost.
