Trivia Edit

  • It was about a 100 meters away from the Piercing Crystal Plains.
  • In the Overlord Twitter Side Story, during the last day of YGGDRASIL, all the monsters in the Grenbera Swamp were deactivated. As a result, they could not attack players like Momonga, nor could they attack the monsters.
