In the boundless reaches of the higher dimensions, there was once a Cosmic Sovereign—an entity who managed the very laws of reality through the Supreme System. But at the peak of his power, he was betrayed by his closest disciples, his soul shattered, and his System forcibly downgraded.
Now, that Sovereign has been reborn as Kaelen Thorne, a disgraced youth in a "Low-Tier" world—a stagnant realm where the air is thin, the mana is coarse, and the inhabitants worship "Legendary" power as if it were the pinnacle of existence.
Kaelen finds himself trapped in a body with a "Common" talent, the lowest rank possible. However, the world's measuring stones are blind to the truth. Residing within his soul is the Mythical-Tier System, a damaged but sentient remnant of his former glory. It sees the world not as a home, but as a resource to be harvested.
While the nobility squabbles over petty titles and "Rare" bloodlines, Kaelen begins a ruthless ascent. Using the Supreme Devour function, he begins to "eat" the talents of his enemies and the energy of ancient dungeons, evolving his soul-root from Common to Epic, and eventually back toward the Divine.
He is no longer a manager of the universe; he is a predator in a world of sheep. From the smallest kingdom to the highest heavens, Kaelen Thorne has one goal: to repair his System, execute his betrayers, and reclaim his seat as the Cosmic Administrator.
"Your peak is my starting point. Your gods are my fuel. And this world? It’s just the first floor."

The Grand Hall of the Oakhaven Academy was filled with the scent of ozone and expectation. Hundreds of sixteen-year-olds stood in line, their eyes fixed on the Prism of Destiny, a floating crystal that revealed one's soul talent.


"Kaelen Thorne!" the High Priest shouted.


A lean boy with sharp, silver-gray eyes stepped forward. Inside his mind, a flickering interface—dimmer than it once was—pulsated with a rhythmic hum.


[Classification: Low Tier World. Energy density: Pathetic.]


Shut up, Kaelen thought. I know where we are.


He placed his hand on the crystal. It remained dull for a long moment before emitting a faint, muddy brown glow.


"Kaelen Thorne. Talent: Common," the Priest announced, his voice dripping with disdain. "Next!"


The hall erupted in snickers. The Thorne family was a fallen noble house, and Kaelen was their last hope. A "Common" talent in a world where the "Legendary" Hero-King ruled was a death sentence for his social status.


Kaelen didn't flinch. Through his blurred vision, the System overlay showed him the truth the crystal couldn't see.


[System Note: The Prism of Destiny is a Tier-1 tool. It cannot calculate your 'Cosmic' origin. Displaying 'Common' to prevent world-collapse.]


[First Quest Triggered: The First Step of the Fallen.]


[Objective: Absorb the ambient energy of the 'Legendary' mana pool in the academy basement.]


[Reward: Talent Evolution — Common \rightarrow Uncommon.]


A Low Tier world's treasure is my starting point, Kaelen smirked, turning away from the mocking stares. Let them laugh. They're measuring a mountain with a ruler.
