Solo Leveling Wiki

The Demon Castle was a S-Rank instant dungeon created by the Architect and inhabited by Demons.


The Demon Castle appeared as a destroyed version of Seoul littered with ruined buildings and set on fire. It had a total of 100 floors and four bosses: Cerberus (1st Floor), Vulcan (50th Floor), Metus (75th Floor), and Baran (100th Floor).

As later revealed by the Shadow Monarch Ashborn, the Demon Castle's appearance is actually based off a version of Seoul from an alternate timeline in which the war between the Rulers and the Monarchs devastated the human world and wiped out the human race.
