The Nether is a hellish dimension that consists of oceans and waterfalls of lava, and most terrain consisting of netherrack and soul sand. It has no natural light, and all the light comes from lava, fire, and glowstone. It also contains Nether Fortresses made out of nether bricks. In addition, the nether is the only source of natural quartz and glowstone.
