Rylos: The Generation Protocol

For ten millennia, the colossal star-vault Rylos has been the isolated domain of the Phoenix Corporation Council, preserving the last remnants of humanity under an ideology of rigid control. Kaelen, an elite Enforcer, is the apex weapon-genetically conditioned and stripped of all emotion-chosen to execute the final, sacred mission: descend to Earth, locate the ancient Genesis Beacon, and transmit the Council's filtered genetic index to begin the new, subservient colony.
But Kaelen's descent into the overgrown, radioactive ruins of the Silent City shatters his absolute belief. Aided by Alia, a fierce scavenger who knows the true dangers of the surface, Kaelen discovers the horrific truth: the Council deliberately purged the resilient 60% of humanity's genetic profiles to ensure a future of obedient specialists.
Now a traitor, Kaelen races against the clock to find the true, complete genetic index. He must infiltrate the highly-defended Safe Harbor Vault to reprogram the Beacon before Rylos arrives. Kaelen's fight for a real future is complicated by the arrival of Lyra, his former partner and the most lethal Hunter Rylos has ever produced, who is tasked with eliminating him and restoring the Council's perfect, sterile order.
Kaelen's final act of defiance is to successfully merge the full genetic registry, forcing the crashing Rylos to launch a diverse, chaotic, and resilient new human future onto the surface, ensuring the species' survival but signing his own death warrant. As the new colony emerges from the wreckage, Kaelen and Alia must become the reluctant guardians of the chaos, preparing for the inevitable war against the surviving, vengeful Council and their ultimate Hunter.
