Minecraft wiki entry for Complete_main_adventure, associated text: At this point, you are in the End. It is made up of end stone and is filled with endermen. There is also a single ender dragon flying around, assuming this is your first time in the End in that world. Note that you can come back to The End at any time after you have killed the ender dragon, and it will not have respawned, if you do not respawn it. WARNING: You cannot get out of the End until you destroy the dragon!
