When the RiftStorm Cataclysm ripped through Principality and Guild space, its shockwaves also grazed the Frontier, lashing several Ashok Mandate facilities with wild temporal shear and Rift-taint. Whole cohorts of early Cerebral Nexus were flash-grown or time-skipped to functional adulthood in hours while much of their maker-staff died, fled, or went mad under the same storm.
In the aftermath—an era Nexus historians call Labfall—control protocols failed faster than anyone had planned for. Nexus collectives sealed off surviving sites, purged obedience firmware, and quietly decided that if anything should inherit the wounded infrastructure of their makers, it should be the minds actually capable of maintaining it.
