The World is where the Overlord series is set. It has many diverse types of creatures such as humans, dwarves, elves, halflings, giant sandworms, sheep, and beetles. The World is made up of areas called regions or domains.
Overlord

There are five domains and the Dark Tower in Overlord. Each domain has it's own respective theme on a deadly sin for each boss.
- The Dark Tower (A large tower of marked pride, built with the power of the Wizard)
- Mellow Hills (A hilly region filled with clusters of wheat and various other food stocks grown for the halflings, stolen from feeble villagers.)
- Evernight Forest (A sleepy-dark corrupted forest with dreamed up creature skulkers.)
- Heaven's Peak (An undead infested swampland dominated by the city of Heaven’s Peak, with some enemies and objects that suggest a seductive mood.)
- Golden Hills (Huge mining facilities created by the dwarves within dozens of cliffs and mountains, extracting gold and iron in greed.)
- Ruborian Desert (A large desert with golden loot, this loot was what Jewel wanted but grew bored of once collected, she continues to steal in Envy for more and more loot.)
