End portal

End Portals are a manufactured Structure Used to travel into The End,it is created when 12 End Portal Frame blocks are inserted with the Eye of Ender, and are formatted in a square-like formation.

As of 1.9 prerelease 4, repairing a portal/spawning in a portal block provides access to The End. Once in The End, there is currently no way out, as there is no portal generated upon arrival like in The Nether, and End portal blocks decay instantly in The End.

Trivia

 * End portals decay instantly when placed in The End.
 * Unlike Nether Portals, End portals have no delay, meaning they teleport you the moment you step into one.
 * End portals are very thin, and only the top face is solid. You can jump through the bottom face, and not the top face.
 * End portals emit light, like Nether Portals.
 * End portals do not use an ordinary texture made up of 16x16 pixels. It seems to have a lot more pixels, making up the 3D face.
