The ruthless corporation that massacred survey teams for alien remnants; now Murderbot's target at its abandoned Milu terraform.
GrayCris is the predatory corporation whose willingness to murder helpless researchers for exclusive access to alien remnants drove the events of Murderbot's past. In the aftermath of the DeltFall massacre and the attack on Dr. Mensah's survey, journalists and lawyers are digging into GrayCris, and their investigation is surfacing a pattern of sketchy contracts and exclusive-use deals across many sites. Among these is an abandoned terraforming project at Milu, outside the Corporation Rim, which GrayCris walked away from without explanation.
Murderbot deduces that the Milu terraform was never real, but a cover for recovering and studying alien remnants or strange synthetics, and that GrayCris let the derelict facility be left to break up in the atmosphere to destroy the evidence. Proving this is exactly what Murderbot means to do.
Principal antagonist organization; the corporation whose buried crimes at Milu are the object of Murderbot's mission.
