World
Minecraft dimensions
The Overworld, the Nether and the End — three worlds with three sets of rules for travel, mob spawning, building and what generates where.
The Overworld
Where you spawn, and the only dimension with a day-night cycle.
The Nether
A compressed, lava-filled dimension where distances shrink eightfold.
The End
A void dimension of floating islands, the Ender Dragon, and elytra.
