The End



The End is a dark, space-like dimension consisting of separate islands in the void made out of end stone.

Accessing


To access the End, the player must go through the process of finding a stronghold using eyes of ender, finding the portal room, and activating the end portal in the end portal room. The room consists of a 5x5 square of end portal frames, with the corners cut out, making a total of 12. The portal hangs over a lava pool, with a staircase leading up to it. A silverfish spawner sits on top of the staircase.

The player can activate the portal by placing 12 eyes of ender into the 12 end portal frames. Each frame block has a 10% chance of generating with an eye in it already, meaning the player may not necessarily use 12 eyes to activate it. Once all the eyes of ender are placed, the portal activates and emits a loud noise. As soon as it is activated, the portal destroys all blocks in the central 3×3 square, including bedrock or another portal frame, and replace them with the end portal blocks that can teleport an entity into the end dimension. Upon jumping into the portal, the player immediately arrives in the End along with any prior entities that may have teleported.

Environment
The End consists of one large island surrounded at a distance by many smaller islands, all mainly comprised of end stone. There is a gap between the central island and the outer islands of about 1000 blocks with nothing but the void.

The starless sky and the void of the End are both composed of a blank, static pattern. The daylight cycle is absent in the End, similar to the Nether, being replaced by a constant dim light.

Most items and blocks function in the End exactly as they do in the Overworld, with a few notable exceptions:


 * Beds and respawn anchors cause an explosion 25% stronger than TNT and cause fires when one attempts to them, as beds do in the Nether and respawn anchors in the Overworld. (Villagers, if somehow brought in, can still use beds safely).
 * Compasses are unable to find the original spawn point, (except for aiming for Lodestone) as spawn points cannot be set within the End.
 * Clocks are unable to determine the position of the sun and moon, as there is no daylight cycle in the End. Clocks instead spin randomly as they do in the Nether.
 * Nether portals cannot be activated by the player in the End (although they can be placed through commands or external programs and editors).
 * Fire burns indefinitely on bedrock, but does not naturally spread onto other blocks of bedrock, as with netherrack.

Biomes
There are 5 biomes that make up the End $$. Beds also still explode if the biome is set in the Overworld. $$, all End biomes are classified as a single biome, which is. In both versions, if the biome is set to end in the Overworld, the sky appears as a light gray version of the normal Overworld sky.

Main island
All players begin their exploration of the End with the main island. Unlike Nether portals, entering the end portal instantly teleports the player to the End, giving no time to back out. Upon arrival, in the end, the player materializes on a 5×5×1 obsidian platform with 3 layers of air blocks above it. The platform can generate on the island, within it, or at a short distance from it, close enough to throw an ender pearl to reach the island. It always generates centered on the coordinates (100, 49, 0) with the player facing west.

Once the player enters the End, the only way back is to die or defeat the ender dragon. The dragon spawns naturally and flies around above ten towers of obsidian arranged in a circle around the central Exit Portal, which fills up at the end of the battle. On top of each tower lies an end crystal, some of which are protected by cages of iron bars. These crystals heal the dragon, but can be destroyed by hitting it (even with projectiles). Destroying the crystal while the dragon is healing damages the dragon.

Once defeated, the dragon goes to the exit portal at (0, 64, 0), rises into the sky and disintegrates, with bright beams of light flashing from its body. It then explodes, drops 12,000 (first dragon) or 500 (all subsequent dragons) experience orbs, activates the exit portal, and generates one end gateway portal (first 20 dragons only). This gives the player access to the End's outer islands. Atop the exit portal lies four torches and the dragon egg. After killing the dragon, it can be respawned an unlimited number of times by placing four end crystals on the sides of the exit portal. Respawned dragons do not drop another dragon egg.



Once the player enters the exit portal, the "end poem" is displayed, therefore "completing" the game. The player then respawns wherever their spawn is set in the Overworld or in the Nether, and may return to the End through the same portal (or a different portal from another stronghold); the End remains in the same state as the player left it. The obsidian platform is regenerated each time a player enters the End, meaning that any blocks or block entities placed in the 5×5×4 space of or above the platform are destroyed and replaced with obsidian and air blocks.

Outer islands
The End's outer islands are more diverse than the main island. When a player enters one of the End gateway portals that generate after killing the dragon, they are instantly teleported over the ~1000 block void to the outer islands. These gateway portals are easiest to enter through the use of ender pearls, due to the one block tall gap between the bedrock blocks, but can also be entered by placing water and swimming through, using a trapdoor or piston to force the player to crawl, or with skilled use of a pair of elytra. There are other ways of getting to the outer islands, such as flying the 1000 blocks with elytra and firework rockets (assuming the player already has elytra), making a piston flying machine, or even possibly making a 1,000 block long bridge; however these ways of crossing the void are extremely inefficient.

The outer islands vary in size. There are occasional "mini islands" in the gaps between the larger ones, generally with nothing on them (occasionally they generate end gateways that return the player to the obsidian platform). The larger islands can also vary in size but are generally a hundred to several hundred blocks wide. The gaps between these islands are generally short enough that players can travel between them via ender pearls.

These outer islands generate infinitely (until you reach the World Border), topped with a forest of chorus trees that may be harvested for its chorus fruit, and perhaps chorus flowers, to grow it in the Overworld. The player may find end cities (which may generate ships with them) on these islands, which hold valuable loot. Pairs of elytra and the dragon head can be found exclusively on end ships.

Mobs
The End is home to three naturally occurring mobs:
 * Endermen spawn naturally throughout the entire dimension.
 * The ender dragon spawns once naturally on the central island, but can be respawned by placing 4 end crystals, one on each side of the exit portal.
 * Shulkers appear within end cities on the outer islands. They do not respawn once killed.

Other mobs except for the wither may be sent into the End through an end portal. (The wither can still be built in the End as usual.)

Naturally generated
Naturally generated includes blocks that are created through the world seed.

Naturally created
These blocks are created through a combination of events that lead these blocks to be placed by natural causes, not by the player.

Structures
These blocks are generated as part of end cities, but only when the "generated structures" option is on.

Folder
$$, the End is saved in the same way normal worlds are, in the  subdirectory of the world save. Deleting the DIM1 directory resets the End, including all player-made changes.

Trivia

 * On Windows 10, the player can set their render distance to a maximum of 72 chunks (1152 blocks) without editing the game files, making the outer islands visible from the main island.
 * Instead of a normal soundtrack, End's soundtrack feature a glitched, distorted version of some of the Overworld soundtrack.
 * In 18w43a, due to a bug, there became slices in the end that lasted hundreds of thousands of blocks and then the end generation resumed. https://bugs.mojang.com/browse/MC-159283
