Dimension

A Dimension in Minecraft is a huge procedurally-generated world to explore. In the vanilla game, there are three dimensions: the Overworld, the Nether, and the End. Many mods add new dimensions, including the possibility for the player to create many custom dimensions in the same save.

Vanilla Dimensions[edit]

The following is dimensions that are part of the core Minecraft World:

Dimension DIM-ID Mod Access Description
Nether -1 Minecraft Nether Portal, a minimum of a 4x5 obsidian frame set on fire Also known as Hell, the Nether is a giant cavern full of Netherrack, Lava, and dangerous mobs. Traveling one block in the Nether is equivalent to traveling eight blocks in the Overworld.

The End 1 End Portal, found in an overworld Stronghold and activated with Eyes of Ender Also known as Sky, the End is a floating island of End Stone full of Endermen and guarded by the Ender Dragon boss.

Torment -38 To initially enter the Torment dimension, the player must summon the Lord of Torment using a Torment Scroll. Then, they must battle it until it has half of its health depleted (250 health points, or 125 hearts of health points). When this point is reached, the player and boss will be teleported into the dimension. The Torment Dimension is a series of mazes with treasure rooms (3 per maze) and the floors of the paths made from Torment Stone. The walls and the ceiling are made of an invisible bedrock-like block (breakable in Creative Mode). At the end of each maze there is a portal which will transport the player back to the overworld.
Mirror Dimention -39 Magic Mirror A dimension of 9x9x9 rooms separated by mirror surface blocks. When you first enter this dimension the demon trapped inside will take on the form of the player who enters the mirror and try to kill them. Once the demon has been slain the mirror will turn into a hollow mirror, the demon won't return leaving you a room to do what you want with. Also the mirror surface blocks can not be broken however placing another mirror on one of the walls and having an altar nearby will allow you to travel between the rooms.
Spatial Storage Dimension varies Applied Energistics Used for Spatial Storage, players may be transported too, and trapped if they're not careful.

Mining World 6 Aroma1997's Dimensional World Just craft some Stone Bricks together with a Pickaxe and you get a special kind of Bricks. They are a little harder to break than normal Stone Bricks and they open you up the ability to visit a new world, the Mining World. Just build a five blocks high and four blocks wide wall with a three by two hole in the middle(same shape as a Nether Portal). Then you need a new Tool to actually create the Portal. Craft a few Stone Bricks, a Flint and Steel and a Stick together to get the Portal Igniter (Portal Multitool). Then right-click the Portal Frames with it. Similar to the overworld, but completely flat. Intended for mining and quarries.
