In Year Zero of the Shattering (Y.S. 0), Earth was torn apart by the Great Rift, a cosmic fissure that unleashed radiation and triggered a mass mutation. Over 70% of the population vanished, transforming into monstrous beings. The wealthy and fortunate managed to escape to the Sky-Ark, leaving billions behind on the ravaged Earth. A century later, under a perpetually overcast sky, the remaining humans are enslaved, forced to live in ruins and the Undercity, serving three dominant monster factions: The Silent Rot (former humans now absorbing memories), The Vitae Dominion (graceful yet cruel vital energy predators), and The Feral Collective (bestial beings transformed by mutated lunar cycles).
Kaelen Vance, a young man from the Undercity, grows up with a fierce determination to uncover the truth behind the Great Rift—not just to escape a life of servitude, but to find a way to end the disaster plaguing Earth. A week before he is forced to join one of the monster factions, Kaelen embarks on his secret mission. However, his plans shatter when an accident in an ancient ruined laboratory traps him in an explosion of residual energy that fuses the genetic essences of all three monster factions within him.
Kaelen not only survives; he transforms into The Apex Chimera, a hybrid being wielding powers from Thralls, Crimson Eidolons, and Lunar Strikers. He is now capable of absorbing memories, moving with shadow-like speed, and partially transforming into a beast. Yet, this extraordinary power comes at a terrible cost: each time he uses his abilities, he must fight against primal urges, bloodlust, and emotional emptiness that erode his humanity.
Driven by the desire to preserve what remains of himself and seek answers, Kaelen joins The Aetherium Collective, a secret resistance group that believes the key to defeating the monsters lies in scientific understanding and ancient technology. With the Echo Codex—a nascent artificial consciousness awakening within him to guide and modify his powers, albeit at the risk of eroding his humanity—Kaelen must fight not only the monsters outside but also the monster within.
Can Kaelen hold onto his humanity? Which factions will he battle, or perhaps, will he become humanity's last hope in uncovering the Great Rift's secrets and restoring the broken world? Follow Kaelen Vance, The Apex Chimera, as he fights back against the encroaching darkness, striving for a pact with the broken sun.
