Minecraft Lore (TO BE CONTINUED)

I'm bored under Quarantine. And what do I do when I'm bored under Quarantine?
Shorty: ROLEPLAY!!!!!
Well, yes, but actually no. I figure out Minecraft lore!!!! You might be all like "But, KarmaRi, there's nothing to figure out in Minecraft. Everything is a cubic meter, and it defines the laws of physics. That's all there is to it." But, my friends, that is where you're wrong. Haven't you ever wondered why there's a Nether? An End? Why are there these strange creatures that we have never seen in real life, or even movies? THAT is what I'm going to find out. Sure, MatPat and Austin have figured out a lot of this. Yes, they are WAY smarter than me. BUT I've got a few theories myself. So, my friends, I present to you, the Minecraft lore.
