Finding the Far Dragon
In order to find the Far Dragon, you must go to the Farlands directly north of X:0 Z:0. You can tell you're going the right way by seeing black or orange coated Villagers that will disappear after a few seconds, the sightings will increase as you near the Farlands... Eventually you will see a flat area with grass the same color as grass in an ocean biome. There will be sand with cacti growing out of these sand patches, there is an entrance to the Farland dungeon in between two 12-block high cacti. The entrance is marked by a descending cobblestone staircase, proceed downwards...
40 blocks down there is a cobblestone room with 5x4x5 open space and a glowstone ceiling. A Beastboy (another discontinued mob) spawns in the room, he is hostile. Upon death beastboy will drop 1-4 bones. Next there is a long 3x3x3 hallway lit with torches and a "monster" (a discontinued mob with the default skin) guard.
Form here you enter a nether fortress-like structure made of sandstone, it is patrolled by hostile pigmen (Not Zombie pigmen, discontinued pigmen) who wield stone swords. In the top of the structure you'll find Green-coated villagers and another staircase leading down, the villagers sell items like food and health potions for bones (which all of the re-continued mobs drop).
When you finally reach the bottom you will be in a room that, upon pressing a lever, becomes open to the surface via TNT. The lever is also hooked up to a textureless block that, upon recieving a redstone pulse allows Far Dragons to spawn rareley around the Farlands. The block also spawns 6 human mobs and 1 Rana mob, these mobs will attack you and you must kill them.
Once all the human Mobs are killed you should proceed out of the Farland dungeon, either go back the way you came, or pillar up the newly opened ceiling. You can now find the Far dragon very, very rarley.
