GrayCris's abandoned terraforming facility outside the Corporation Rim, suspected cover for alien-remnant theft and Murderbot's destination.
Milu is a world outside the Corporation Rim whose failed terraforming project, run by GrayCris, was declared abandoned after a long period of station inactivity. A small company from outside the Rim has recently filed to take possession of the derelict, setting up an automated tractor array to stop the facility from breaking up in the atmosphere and preparing to send an assessment team. Murderbot believes the terraform was only a cover for recovering alien remnants, and that whatever GrayCris left behind is the proof Dr. Mensah needs.
Reaching Milu is difficult: cargo routes were discontinued except one originating at HaveRatton Station, and its transit station carries a floating population of under a hundred, making it a place where any stranger would be noticed. It is Murderbot's chosen destination.
Destination and mystery box; the abandoned facility Murderbot means to infiltrate to expose GrayCris.
