In the decaying underbelly of Sector 9, Kaelen Cruz lives in constant fear of losing his sister Shae to mercury-black cyber-poisoning. The corporate vaults of Aethel-Corp hold the only cure, protected by invisible biometric laser grids that instantly shred any organic tissue attempting to breach their sterile vault rooms. Desperate and out of time, Kaelen undergoes a brutal operation with rebel optometrist Dr. Valerie Vance, ripping out his own healthy eyes to implant unstable ultraviolet-reactive prism corneas that can make the invisible security lasers visible. As Kaelen infiltrates the high-security bio-vault, the intense UV radiation begins scorching his optic nerves. In his agonizing state of sensory overload, his vision splinters, revealing the glowing, neon-violet digital ghosts of murdered whistleblowers who walked these paths before him. Balancing his rapidly decaying eyesight against the relentless hunt of Vektor's search-and-destroy droids, Kaelen must synchronize his physical movements with these dead guides to survive. Escaping by utilizing the ghost-trails to blindside Vektor's sensors, Kaelen delivers the cure to Shae. Though completely physically blind, his scarred corneas retain a permanent gift: a soft, glowing lavender vision of Shae's restored life and the spectral guides who will forever walk beside him in the deep dark.
