End gateway

The End Gateway Portal is created after defeating the ender dragon and is used to gain access to the surrounding islands.

Generation
End gateway portals generate after defeating the ender dragon for the first time.

Structure
The End gateway portal is composed of bedrock blocks surrounding a 1 block teleporting block opening. When it is generated, a purple beacon effect shoots out vertically from the top and bottom, which will then slowly dissipate.

Due to its size, it is only accessible using ender pearls, or by riding pigs, boats or minecarts. The end gateway portal is used to warp to other end islands depending on the direction of the ender pearl throw.

Trivia

 * When used in the overworld or Nether, the player is not teleported, but the gateway will still emit a beam of light. (Note: The only way the portal can appear in the overworld/Nether is through use of commands/third party software.)
 * When a player or entity enters the gateway, it will output a yellow beam.
 * When an arrow is fired into the gateway, it will output a green beam.
 * The Portal takes you about 1000 blocks away from the main island
 * The End Gateway Portal is technically optional for getting to the new islands. However, as they are separated from the central island by several hundred blocks of void, not using the portal is extremely impractical unless you're in Creative mode.
 * Theoretically it's even possible to get there before you have defeated the Ender Dragon. In practice, however, the dragon will likely make it impossible to actually do it.
