Nether Wastes

The Nether, or Nether wastes, is a biome found in the Nether.

Description
The Nether is a barren biome made of netherrack with expansive lava lakes and occasional glowstone clusters.

Ghasts, zombie pigmen, magma cubes and endermen may spawn here. Nether fortresses can generate in this biome.

$$, if the Nether is used as the biome for Overworld generation, a bedrock ceiling generates at altitude 128. If a river generates in the Nether biome, the bedrock ceiling does not generate over the river biome (which exposes sunlight). The terrain consists entirely of stone, without any netherrack or nether related block generated. Although the terrain is entirely stone, no ore is generated (including dirt, gravel, andesite, etc). Caverns and lakes (with red colored water) still generate. The player is still able to place water in an Overworld Nether biome, but trying to sleep in a bed still causes an explosion.
