If death is the inevitable end, what meaning lies in the journey?
In a world where every breath draws closer to silence, Perpetual Motion explores the fragile beauty of existence—the spark that refuses to be extinguished despite the shadow of fate.
The world's mana, once the source of life and progress—has begun to rot.
An unknown energy has infected the flow of mana, twisting it into something vile and unnatural. From this corruption, the Cursed Beings were born—soulless creatures of devastating power that swept across the realms, tearing through cities, kingdoms, and civilizations. As the world teetered on the edge of extinction, salvation came in the form of an enigma: The Tower.
No one knows where it came from. Only that it descended when all hope seemed lost, offering strength, awakening power, and summoning chosen souls to face impossible trials. Those who return are forever changed. Most never do.
Caught in this storm is Zen, a boy who cares nothing for power or destiny. All he wants is to free his sister from the chains of demonkind. But freedom comes at a price.
Captured. Tortured. Experimented on—Zen is forced into the Zeroth Trial, the Tower’s secret first test that etches a class into the soul by casting it into memories older than time. But something goes wrong.
An accident during the ritual shatters the veil between worlds—and Zen awakens in the forbidden Spirit Realm Trial, a place meant for beings far beyond human.
Now, trapped in a trial not meant for him, hunted by spirits, demons, and echoes of forgotten gods, Zen must survive a world that was never supposed to know his name.
He has no grand prophecy. No chosen blood.
Just a promise—and the fury to keep it.
