Lemegeton

Lemegeton is a hall located on the 10th Floor of the Great Tomb of Nazarick.

Background
The Lemegeton stands just before the entrance into the Throne Room. Here one of the last lines of defense of the dungeon were laid to 'welcome' intruders. The room itself was never completed as it was missing five golems that are situated in the the 72 niches. This was because the creator of the golems had gotten bored and abandoned completing it.

Layout
A domed hall that looked like a theater, with four-colored crystal lamps that glittered from the ceiling. There were 72 niches in the walls. Many of them were filled with statues that resembled demons.

Features
The Gates of Judgement: At the end of the hall were a pair of giant doors. They were a majestic set of double doors that were over five meters in height, and covered in intricate carvings. The left side was shaped into a beautiful goddess, while the right was made to resemble a cruel demon. So realistic was their design that even from across the room, one felt like they would attack.

Trivia

 * It was named after the Lesser Key of Solomon, which was a magical grimoire.
 * In the Web Novel, Golems of the Lemegeton were made from a Prismatic Ore that Ainz Ooal Gown acquired from the Seven Hidden Mines. However, they ran out of the metal after the mines were stolen from a rival guild.
 * The doors in the Lemegeton are unnamed throughout the Light Novel series, though in Volume 9 Jircniv Rune Farlord El Nix in awe at the doors dubs them the Gates of Judgment due to their intimating appearance.
