Great Tomb of Nazarick
The Great Tomb of Nazarick, usually referred to as Nazarick, is the guild headquarters of the guild Ainz Ooal Gown in YGGDRASIL. Because it was a PK guild, there were many attempts to conquer the dungeon, all of which ended in failure.
After Nazarick was transported to the New World with Ainz and its custom NPCs, who became sentient as a result, the former began strengthening the tomb and collect information to protect it from possible threats. However, the NPCs mistook his intentions as preparing to take over the New World and began making their own plans. By the time Ainz realized this it was too late and he had no choice but to play along. This eventually led to Nazarick becoming its own nation, the Sorcerer Kingdom.
- Ainz Ooal Gown / Momonga
- The protagonist/main character and the only remaining member of the Guild of Ainz Ooal Gown. Originally he was a simple salaryman playing a VR online game, but after he was transported to the New World, he decides to make himself a legend in hopes of finding his old guildmates. To facilitate his search, he changes his name from Momonga to Ainz Ooal Gown. While Ainz initially accidentally set Nazarick on a course for world domination after a comment he made was misinterpreted, he slowly grows into his role as a leader after deciding to create a kingdom where humans and non-humans are equal. As he has the form of a lich, he doesn’t need to eat or sleep, can’t be poisoned or killed by conventional means, but also suppresses his emotions and empathy. Because of his formerly high level in Yggdrasil, he can easily overpower even the strongest of magic casters in the new world and while he lacks the skills of natural warriors, he compensates for it with raw strength. Over time, he has learnt how to improve fighting with physical weapons, but his greatest asset remains his strength. Ainz also has access to a wide variety of instant death and summoning spells which, though ineffective against fellow players, work very well against the inhabitants of the New World. He also has an array of items he purchased with real money back in Yggdrasil, which give him abilities ranging from summoning extremely high level items (most of which belong to his guildmates) from the Guild’s bank to instantly casting a spell that usually has a long casting time. When Ainz travels as an adventurer, he uses the alias “Momon” which later becomes “Momon the Dark Hero”. In the CD drama #2, his real name is revealed to be Satoru Suzuki.
