Nether

The Nether (also known as The Nexus or Hell) is a dimension that was added to Minecraft Pocket Edition in Update 0.12.1.

Access
It can be accessed by a 4x5 (Upto 23x23) Nether Portal consisting of Obsidian that needs to be ignited using Flint and Steel.

Landscape
The Nether is a hell-like dimension, consisting of low light levels, oceans of lava, and most terrain consisting of Netherrack and Soul Sand. It also contains Fortresses made out of Nether Bricks, in which Nether Wart can generate.

The Nether includes random veins of Nether Quartz Ore, Glowstone and Gravel. Bedrock generates at the topmost and bottom most layer of the Nether.

The Mobs found in the Nether are:
 * Zombie Pigmen
 * Wither Skeletons
 * Skeletons (Have 20% chance to spawn instead of Wither Skeletons)
 * Magma Cubes

 * Ghasts

Trivia

 * If the player attempts to do so, the bed will explode.
 * Water cannot be placed in the Nether as it will evaporate immediately.
 * Lava in the Nether flows faster than in the Overworld.
 * Zombie Pigmen became neutral after The Nether was added into the game.
 * One block in the Nether equals 8 blocks in the Overworld.
 * This makes travelling the Nether an efficient way to move across the overworld.
