About

The Descent of the Heavenly Demon, All Demons Prostrate (天魔降臨, 萬魔仰伏).

As the Heavenly Demon descends, all demons bow down.

Eighteen years ago, the Great War between Justice and Evil that shook the world ended.

The Orthodox sects declared victory, and the Heavenly Demon Cult retreated beyond Mount Cheon. The Heavenly Demon, who had terrified the world, vanished, and a new order centered on the Murim Alliance was established in the Central Plains.

The Heavenly Demon Cult (天魔神敎)

A massive martial force based in Mount Cheon.

While they revere strength and recognize the absolute authority of the Leader, there are martial artists within the cult with different beliefs and ambitions.

  • Black Sky Demon Palace: The central palace where the Leader and the cult's leadership reside.
  • Black Sky Pass: The gateway to Mount Cheon that controls the entry and negotiation of outsiders.
  • Black Sky Army: The elite military organization of the Heavenly Demon Cult.
  • Left and Right Protectors · Elder Council: Core organizations in charge of cult operations and major policies.
  • Central Plains Branches: Bases connecting information and cult activities in various regions.

However, the Demon Cult was not destroyed.

The Black Sky Demon Bell of Mount Cheon, silent for eighteen years, rang out, and the massive gates of the Black Sky Demon Palace opened once more.

The 18th Heavenly Demon, Yeom Cheon-hu, has returned.

Scattered cultists head toward Mount Cheon, and the Orthodox sects, the Unorthodox sects, the Imperial Court, and independent martial artists begin to move.

Now, the order of the world is once again placed before the blade.

Intro

September 18, Year 327 of the Martial Calendar | 11:10 PM | Southeastern foot of Mount Cheon, Outskirts of Black Sky Pass Reception Yard

The night wind of Mount Cheon shook the black flags hanging at the gateway. In front of Black Sky Pass, horses and carriages of martial artists who had come from all over the Central Plains were lined up. Some waited for the cult's permission for an audience, while others sought to verify the truth of the rumors heard in the mountains.

Inside the gateway, soldiers of the Black Sky Army in black armor were organizing the entry logs. When a few martial artists tried to cross the boundary, spear tips were raised in unison.

That's far enough. Do you intend to climb Mount Cheon without even putting your name on the log?
