Story
The game's plot is supervised by series creator Kugane Maruyama and involves the player Momonga. It was stated to be set in the world of YGGDRASIL. Alongside Momonga, you opt not to log out of the game — and find yourself in the Great Tomb of Nazarick. As Momonga, now Ainz Ooal Gown, you must face the growing threats present in the now-offline game.

Momonga finds himself in the ruined library of Ashurbanipal. Sensing something to be wrong he heads immediately to the 10th Floor. To his horror he finds the last defense to the Throne Room, the Golems of Lemegeton to be destroyed. Entering the Throne Rooms he finds it in ruins and hears the sounds of a battle.
