Early in the 21 Century, the Tyrell Corporation advanced Robot evolution into the Nexus phase - a being virtually identical to a human - known as a Replicant. Replicants were used Off-world as slave labor. Those who escaped to Earth were hunted by Blade Runner units, ordered to kill any trespassing Replicant upon detection.In 2022, a Replicant attack on the Tyrell Corporation forced the company into bankruptcy and erased all records or existing Replicants. The surviving Nexus 8 models disappeared with the help of the Replicant Underground. Many Replicants remained in servitude.In 2027, Aahna "e;Ash"e;Ashina, rejoined the Blade Runner department, although her superiors are unaware that her lover Freysa, is a leader in the Replicant Underground.While investigating a report of a rogue Replicant, Ash discovered that a Nexus 6 Replicant, Yotun, whom she had failed to retire 12 years previously, had somehow become the leader of a Replicant guerrilla army.Yotun ordered his army to launch an all-out terrorist attack upon Los Angeles and compelled all Replicants in the city to revolt against their masters.Freysa seemingly joined Yotun's crusade in an effort to stop him, however, he blinded her in one eye when he discovered her subterfuge. Ash rescued her lover and set out to bring Yotun down, once and for all. However her superiors have become suspicious of Ash's motives.Meanwhile, Yotun has started to succumb to the ravages of time, and even the regular blood transfusions from his loyal supporters that he was using to rejuvenate himself have started to fail.Convinced that an old diary of Eldon Tyrell holds the key to his survival, Yotun sent Pekka and another Replicant off to retrieve the journal from a maximum security vault. There Pekka was killed by Blade Runner Marlowe
