More Events and Post-EndGame Events

New random events or callable events... let me explain myself.

Before you kill enderdragon, there will be some events that are not that dangerous, like stronger enemies or things like that.

before you kill enderdragon, there will be events like more animals like bunnies appearing.

And after you kill enderdragon, there will be events that are more dangerous, like an lunar event where more wolves are appearing and skeletons get a resistance effect, you are in post game, so you have more enchantments like: Punishment and Sharpness. so it doesn't affect the player that much. 

I hope things like this appear in future versions of Minecraft.
