A Nether Fortress is a naturally-generated structure found in The Nether. Nether fortresses were first introduced in the 1.9 Pre-Release and 0.12.0 for the Pocket Edition. They include bridge structures constructed of Nether Brick, Nether Brick Fences, and Nether Brick Stairs. They are the only place that Nether Wart can be naturally found. They also often contain many Blaze Spawners.

Carbuncles are a group of furuncles and generally extend deeper into the skin. People with weakened immune systems are more likely to develop a furuncle or carbuncle, although furuncles are quite common. Furuncles start as a small, red painful area on the skin. They may be caused by staph, other bacteria or fungi that infect a damaged hair follicle.
