The Grenbera Swamp was a wetland region where toxic fog-covered areas scattered the terrain of the poison swamp.
- Great Tomb of Nazarick: Located on an island in the deepest reaches of the swamp.
- It was about 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.
- The swamp makes a brief cameo in the Manga though it is not properly named until the Overlord Prologue.
