They brought back a hero. They may have unleashed a god. Lina is awake. Rescued from the clutches of OmniCorp's ruthless Commander Kael, she is the resistance's ultimate symbol of hope. But her freedom comes at a cost. The experiments performed on her have activated the Crimson Cipher, an ancient power woven into her DNA that could rewrite the very fabric of technology. Her return draws the attention of Zachariah, a powerful and enigmatic figure who offers a new path—not of war, but of global restoration. He reveals that Lina is the key to awakening the "Source," a dormant planetary network that could render OmniCorp obsolete. To reach it, a small team must journey into the Sunken City, a lost world beneath the ruins, where feral machines hunt in the darkness. With Kael's forces closing in and a deadly assassin on their trail, Lina and her psychic guardian, David, must embrace their symbiotic powers. They are the world's last hope, on a desperate quest to unlock a power that promises either salvation or annihilation
