Dark Heaven Sect

Description
The main antagonists. In the previous timeline, they conquered the entire Murim. In the current life, they lose at every turn due to Joo Seo-Cheon thwarting their plans.

2 of the 7 stars division, Merak and Megrez, is killed by Joo Seo-Cheon, as well as the Head of Records Department, whose name remains unknown. The leader of the Dark Heavens sect was invincible in the previous timeline, but after losing too many assets to Joo Seo-Cheon, he became weak. He wanted to try conquering the world because he thought he had the strength to do so, which irritated Joo Seo-Cheon, because so many lives were ruined because of him.
