Nether Fortress

Nether Fortress is a generated structure that will spawn in the Nether dimension which will be added in Update 0.12.0. They are large structures consisting of Nether Brick Blocks.

Structure
Nether Fortresses have a complicated structure with various rooms, including-
 * Lava Well Rooms
 * Rooms with nether brick stairs in the center and soul sand at sides of the stairway containing two 2×5 rows of nether wart growing on it.
 * Rooms with blaze spawners (normally 2 per fortress), which can have nether brick stairs leading up to them. The rooms also have nether brick fences.
 * Rooms with four exits. Some of them lead only to netherrack.
 * Rooms with a "stairway" of nether brick placed against a wall, leading up to the floor above.
