End update

Sulfur caves=end update. Defeat "rebel" end dragon and either return the egg to the queens nest in the end to make yourself an ally to the ends people (enderman) or keep the egg and become their enemy (different loot and ways of obtaining it for different choices). Switch between enemy and ally simply by taking and returning the egg whenever you want. More end mobs could be added to the end as well. The nest=giant amethyst cave. Switch normal amethyst to "charged" amethyst by returning the egg to it's nest (charges all amethyst crystals within a 20 block range). The crystals, after being charged and removed, will keep their charge. The crystals still attached will lose and regain their charges as the egg is removed and replaced. Bring amethyst crystals from overworld to nest to get them charged and also "grow" more. Crystals can only be grown and charged in end nest. Add sulfur lakes that hold large diamond veins, but the only way to get to them is by brewing a potion that gives you temporary immunity from the toxins while allowing you to breathe under water. The gasses from the lakes spread 15-20 blocks in all directions. To make the potion, collect different items, such as potion of water breathing and potion of healing or potion of regeneration, then brew it together in a cauldron over a soul campfire surrounded by charged amethyst crystals. You would have a limited amount of time before needing another potion, making it crucial to brew more than one of them.
