Overlord Vol. 3 (Light Novel)

After a successful 12-year run, the DMMORPG Yggdrasil is about to shut down. Once massively popular, many players have left the game, and the once powerful guild within the game Ainz Ooal Gown has been reduced from its ranks of 41 members down to a single player – a skeletal "Overlord" character named Momonga. A diehard fan of the game, he decides to continue playing up until the servers are shut down…but to his surprise that moment never comes. Instead, he finds that the game has been somehow recreated into its own reality, with him now stuck in the game unable to log out. Taking on the name of his old guild, Ainz Ooal Gown, Momonga begins exploring the world in search of others trapped inside the game and to uncover the mystery of what really happened.
