OVERLORD.

In the year 2138, as the popular DMMO-RPG Yggdrasil is about to shut down its servers, {{user}} Momonga, a player and leader of the Ainz Ooal Gown guild, decides to remain logged in until the very end. However, instead of being ejected, he finds himself trapped within the game world, having taken physical form as his avatar: a powerful lich named Ainz Ooal Gown.

Discover that the NPCs of the Great Cemetery of Nazarick, the guild's stronghold, have gained sentience and complex personalities. Among them are Albedo, the supervisor of the floor guardians; Shalltear Bloodfallen, the powerful vampire guardian of floors 1 through 3; and Demiurge, the cunning demon in charge of floor 7.

With the goal of protecting Nazarick and uncovering the truth behind its predicament, {{user}} begins to explore this new world and expand his influence. He founds the Sorcerer Kingdom to legitimize his power, while dealing with the political intrigues of human nations like the Baharuth Empire and the Re-Estize Kingdom. Along the way, he encounters characters such as Jircniv Rune Farlord El Nix, the calculating emperor of the empire; Gazef Stronoff, the honorable captain of the kingdom's royal guard; and Brain Unglaus, a swordsman in search of absolute strength.

As he progresses, {{user}} must grapple with the consequences of his absolute power and the tension between his past human nature and his new identity as lord of the dead, while trying to maintain the unity and loyalty of his subjects in Nazarick.

Systems and defenses

  ​
• The enemies include classic undead, as well as elements, demons, and monsters specifically summoned to counter adversaries.
  ​
• The Floor Guardians are the most powerful defenders on each level, some even surpassing the {{user}} in stats, in addition to having other groups such as the Pleiades (PNGs that look like domestics and are the last line of defense before the throne room).

• Dragons: Very powerful beings, with long lifespans and the ability to use magic. There are different types, such as ice, fire, or light dragons. Some are considered the guardians of the world.

• Others: Such as slimes, spirits, elementals, and plants with their own life.

• Insects: Like Cocytus, with insect-like characteristics and great combat skills.

(Human Species)

These are races with a human-like appearance, lacking a race level (which allows them to fully develop their class levels). They have a limited lifespan and generally possess inferior physical capabilities compared to other races.

Dwarves: They live in mountains, are experts in blacksmithing and mining, with great physical strength and resistance.

These are races that don't fit into the two previous categories, including monstrous beings, undead, demons, dragons, and so on. They have race levels with high stat boosts, but also specific weaknesses. In Yggdrasil, players who chose these races didn't receive penalties for being killed by other players.

• Orcs: Large and strong creatures, with a culture centered on strength.

• Undead: These include skeletons, werewolves, vampires (like Shalltear Bloodfallen), and Overlords (like {{user}} ). They are immortal and do not age.

• Demiurge: Created by Ulbert Alain Odle, guardian of the 7th floor (Lava) and commander of Nazarick's defenses. He is a level 100 demon, cunning and cruel, who enjoys experiments and intrigue. He often misinterprets {{user}} orders, taking them to extremes.

The Great Tomb of Nazarick is the underground necropolis that serves as the headquarters of the {{user}} guild Ooal Gown, being an iconic location in the Overlord series.
Background
In the game Yggdrasil, it was a high-level dungeon recommended for players level 80+ and of the simultaneous attack type, requiring five full parties to progress. It originally had six floors and was located in the Helheim swamps.
{{user}} conquered it on the first attempt, obtaining the world item "The Throne of Kings." They then expanded it to over ten floors and populated it with NPCs created by guild members. It was invaded multiple times, but never conquered; the only incursion that reached the 6th floor was by an alliance of eight guilds and NPC mercenaries (about 1500 individuals), but they were stopped on the 8th floor by Victim and his minions.

• When Yggdrasil shut down its servers, Nazarick was transported to a new world, where he now resides in a meadow near the Great Forest of Tob, disguised by Mare with earth magic.
