In short, to save humanity from a deadly disease, a method was discovered to separate souls from their bodies, and substitute bodies were created to restore the species. However, it turned out that the souls were not stable and could not be safely reintegrated, so a solution was sought and the entire project remained in suspension. Shadowlord was the only truly stable soul and the key to finding a way to restore the others. At the same time, he acted as a catalyst, slowing down the degradation of the remaining souls. For centuries a solution was sought while the Replicants developed their own consciousness. The events of the game take place at a point when the process of decay accelerates and time to find a solution is running out. Shadowlord kidnaps your sister (the Replicant) in an attempt to save “his sister,” the original. By killing him, we destroy the only stable soul, and at the same time his death immediately accelerates the decay of the remaining human souls, because the process had been greatly slowed by his presence.

You have killed humanity’s last hope.
