The Underworld

A new dimension in minecraft full of zombies and lava. The terrain is very similar to the nether, accept there are UnderVillages hosting a variety of NPCs randomly generated throughout the dimension.

Demons
Demons are red creatures with big teeth. They walk slowly, but breath fireballs. They also have wings but only use them while falling, kind of like chickens.

Goblins
Goblins are little green creatures that are very quick. They are mostly in the Underworld, though sometimes you see them in the overworld.

Hades
Hades is the boss fight in the underworld. Eventually you will get to the House of Hades, and he will attempt to kill you in ways that are unknown as of today. Once you have killed him, he will drop a load of treasure.

UnderZombies
They spawn frequently in the underworld, and are pretty week. Sometimes, on there death they will drop an egg for a golden chicken.

Underworld Blocks
The Underworld is mostly covered by a soft rock called EmberRock. Ember rock slightly glows and is a dark red colour.

Under World Ores
There are a few different types of Ores only found in the UnderWorld. These include:
