Holden Hosenheim is a Division 4 Agent, working under the Shio Branch. His job is to protect the Great Society of the Aarde Union and the Connected City, Shio, from the Revivalists, a narco-funded rebel group that produces and sells a memory enhancing drugs called N-Light. It's a hard job that he is content with. But when an extraction mission goes wrong and Holden's team is wiped out, he and his contact are stranded in Revivalist territory. They seek aid from a comforter who claims to be an old friend of Holden's and insists that his memory has been altered. This revelation puts him in the crosshairs of the Revivalists and tests his loyalties with Division 4. All while Shio teeters on the brink of collapse. And where Shio goes, Aarde goes. (Part 1A)
