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.

A urethral caruncle is a normally benign, red, soft lump found on the posterior of the urethra. Women who have already gone through menopause are more likely to develop these lumps than younger women. Some patients will experience vaginal pain, pain with sex or bleeding from a urethral caruncle, in which case surgery may have to be performed.
