Enchanted elytra - the far end update.

You would be able to obtain the enchanted elytra after completing the End Ship. That's when another portal would be able to take you to another part of the End. There would be new mobs, enchantments, and of course, new music. One of those enchantments would be used on the elytra. The enchanted elytra allows the player to go to space and find planets.
