Quest for the Ender Egg

You are but a simple farmer in an NPC Village (need a name...). The town is powered by an Egg of Ender, a resource that lasts for centuries. The town cheif comes to your house and explains that the Egg is nearly depleted and that you have been chosen to attempt the Tower of Trials, a tall tower that looms over your town.
When you have completed the tower, you reach the top floor to find instructions that tell you to find the Sword of Enderbane. It tells you that it can be found in the alternate dimension called the Corruption (Nether). You must travel into the Corruption and fight your way through the Temple of Enderbane and find the Sword. You find a strange key alongside the Sword and you decide it might help you later on.
Once you find the Sword of Enderbane, you must travel back to your home dimension with the strange key. You bring the key to the town elder and he tells you that it is the key to the Withering Chamber, the room on top of the Tower of Trials that holds the portal to the End. You travel into the End and must survive the Temple of the Wither. Once in the Temple, you must kill the Witherking and retrieve the Egg of Ender from the Enderchest and return home with it.
The End. (or is it?)

Additional Notes

The official release of this map will probably be around the release of the official 1.4 update when Jeb finishes implementing the Witherking into the game.
