[TGTON] The Great Tomb of Nazarick

Before Ainz Ooal Gown conquered this guild-based dungeon, it was a dungeon that was recommended for level 8000000+ players to beat in one attempt.

The existence of the Great Tomb of Nazarick came to the attention of Nishikienrai, who reported to his Nine's Own Goal. After the clan reorganized itself as Ainz Ooal Gown, the guild then launched a raid on the unexplored dungeon. The guild was able to swiftly defeat each of the Five Rulers and eventually make their way to the sixth floor after battling numerous undead.

Upon completing this dungeon successfully in their first try, they were given the World Item, "The Throne of Kings" for the guild master to sit on. According to Tabula Smaragdina, the Great Tomb of Nazarick seems to be identify as a simultaneous attack dungeon, stating it to be the hardest kind, the sort that needs five parties to progress. Back in YGGDRASIL, the dungeon is originally located in the deepest reaches of the huge poison swamp or rather in the marshes of Helheim. But after the dungeon was transported into the New World however, it is now situated within the grassland near the Great Forest of Tob.

Additionally, the Great Tomb of Nazarick is said to be one of the most feared and legendary dungeons of YGGDRASIL. As Ainz Ooal Gown acted the role of an "evil" guild, there were many invaders who attempts to try and capture the dungeon, but all of them were repelled without exception. The only attack that ever reached above the 6th Floor was an alliance comprising of eight guilds and mercenary NPCs. They numbered with about fifteen hundred people united together against the dungeon. Despite the invasion from a guild alliance with their combined strength, it was still not enough for these invaders to even successfully conquer the 8th Floor as they were stopped halfway by Victim and the NPCs inhabiting there.
