The origin of the Double Lair in Solo Leveling

In the Solo Leveling fictional universe, rare Double Lair dungeons can sometimes form – essentially a dungeon within another deeper dungeon, with great variability in difficulty levels.


The Double Lair discovered by protagonist Sung Jin Woo in episode one has special origins – it was deliberately created by the mysterious “Architect” entity who also devised the wider System granting players special powers.

As revealed later in the manhwa, the System’s true purpose is to serve the Architect’s goal of cultivating a worthy human vessel for the rebirth of a long-dormant ancient Monarch. The challenging gauntlet of the Double Lair serves as the testing and selection grounds for the Architect to determine the ideal host for this Monarch reincarnation.
