An AU idea for the Dream SMP characters/personas

Okay, so, what I'm going to write is the description of the AU, how the world function, like what plants, creatures, is there magic and stuff like that. Going to be more of a realistic minecraft minus a lot of magic.
Yea I suddenly thought all this up and was dying to get it out.
Note: This is an idea that anyone can base their own fanfic on.
I also thought it'd be interesting if there were multiple fics based off this AU all connected to the plot or storyline, doesn't have to have important plot points in different fics, I just thought of the perspective of other characters watching from the sidelines.
For me, I like the sense of mystery, seeing from the character's perspective, getting surprised just as much as the character we're seeing the plot through. Maybe in some characters, they might not even know what happened, but just see a huge cloud of smoke in the distance and wonder what's going on.
Uh, I added my input on some areas, hope you don't mind. This is sorta a whole rant/ramble that somehow created an AU.
And about relationships.... it's at the very end if you ever reach it good luck!
About the main characters, it starts off with Tommy and Tubbo opening the up the path to a messy adventure that involved many skilled individuals, I'll talk about that more down below.
