Ainz Ooal Gown seems to have modifications made to his behavior by in-game mechanics, because he demonstrates no moral qualms with killing and other actions that are taboo in the real world. Taking on the name of the guild, Ainz Ooal Gown, as a message to any other remaining players, Momonga begins exploring the world in an attempt to figure out what has happened while searching for anyone or anything that could help him solve this mystery, while ensuring the safety of Nazarick. With no other option, Momonga sets out to learn if any players like himself are in this new world. Momonga has been trapped in the form of his game avatar, leaving him unable to use the normal player functions such as General Message, or even log out. When the shut-down time arrives, Momonga discovers that the game hasn't vanished instead, it appears as if Nazarick has been transported to another world altogether and its various NPCs becoming actual living beings. While saddened by this, he accepts the reality that his friends have their other lives to take care of and decides to stay logged in until the servers shut down. In the minutes before the shutdown he invites the remaining guild members, but of those only one appears and only for a short while before leaving. Now only four of the members remain, the other 37 having quit the game, and only one, a skeletal Lich 'Overlord' character named Momonga, continues to play as the guild leader, maintaining their headquarters in The Great Tomb of Nazarick. Within the game exists a guild, Ainz Ooal Gown, once consisting of 41 members and credited as one of the strongest guilds in the game.

After an intense twelve-year run, the game servers are about to be shut down.
