The Last Echo of Silence

When Kael wakes up inside a cold, huming chamber with no memory of who he was or even what he is he finds himself trapped in a dead facility buried beneath an unknown, silent world. The only voice that answers him is the cryptic, decaying AI of the facility itself, which calls him ‘Echo’. But Kael isn’t human anymore. His bones are metal, his blood is a glowing fluid, and his heart is a core that hums with a terrifying emptiness. As he crawls, climbs, and fights through rusted corridors and automated defences, he uncovers fragments of a past he may not want back. What happened to the world above? Why was this facility sealed? And why does the AI keep whispering, “You are not the first Echo and you will not be the last”? A slow-burn story of identity, sacrifice, and the haunting silence left after civilisation ends.
