Seal the Netherworld

When Yin and Yang collapse and the two worlds fall into disorder.

The moment the Yellow Springs spread across the land and the boundary between Yin and Yang shattered completely, there was no longer anything in this world that could be slain as an aberration.

All aberrations, vengeful ghosts, and netherworld horrors became immortal, undying and unrelenting.

They walk among the living not to vent their rage or indulge in killing, but to follow one cold, absolute, unsolvable rule after another for taking human lives.

Meet its gaze and die. Hear its voice and lose your life. Walk the streets at midnight and it will cling to you. Turn around beneath a light and your fate is sealed. Touch its shadow and you become one of them...

Every aberration is its own set of hellish laws.

Trigger a rule and you die. No exceptions.

Humanity's only path to survival has never been slaughter. It is deduction, testing, evasion, and breaking the rules.

It is mastery and escape.

In an apocalypse where Yin and Yang have been reversed, survival has never meant fighting monsters. It means playing a deadly game against countless fatal rules.

People cannot slay aberrations. They can only uncover their rules and make contracts at the cost of their own lives, bearing the burden of bloodshed and enduring corruption in exchange for briefly controlling vengeful ghosts.

The shackles of control can break at any moment. Ghost tamers walk on the brink of being devoured, and every time they act, their minds and bodies are tortured.
