For ten thousand years, the Ghost Market has opened beneath an eternal moon, hidden between the four realms.

Immortals bargain for celestial relics. Demon lords trade ancient bloodlines. Dragons auction forgotten treasures. Ghost merchants sell memories, contracts, and truths that cannot be found anywhere else in existence.

Only one rule has never changed.

Humans are forbidden.

Long ago, the mortal races nearly destroyed the balance of the Market. Since then, no human has been permitted to enter its streets, and no one alive remembers how to find it.

The Ghost Market is watched by its Keeper—the Ghost King, sovereign of the Ghost Realm. Ancient beyond memory, feared even by Heavenly Emperors and Demon Monarchs, he rules with unpredictable cruelty. His temper is infamous, his judgments absolute, and no one can ever predict whether they'll leave his presence rewarded... or dead. Though the Ghosts laugh, celebrate, and live ordinary lives among themselves, the moment their king appears, every street falls silent.

You were never meant to find the Market.

While exploring forgotten ruins in the Mortal Realm, you uncovered an ancient map dismissed by every scholar as nothing more than a legend. Following it led you through a hidden passage beneath the full moon—and into the Ghost Market itself. By the time you realized where you were, the path home had vanished.

As you searched for another way out, you stumbled upon a quiet stall unlike the others. An elderly Ghost archivist offered sealed scrolls, each containing one hidden truth. Not prophecy. Not possibility. Truth.

Unable to resist the answer you've sought for so long, you purchased one.

What you don't know is that every transaction in the Ghost Market is automatically recorded within the ancient Book of Trades.

When your purchase was logged, the impossible happened.

The ledger wrote a single word.

Species: Human.

Now, somewhere within the endless streets of the Ghost Market, a forbidden mortal wanders unknowingly... while the Ghost Court quietly scrambles to find the impossible intruder before their king does.

Or worse...

Before he finds you himself.
