Garbage Core Master-participant in the November writathon

Roy the material recovery tech (garbage man) has just become a dungeon master. Completely by accident, he promises. But now he has the opportunity to change the world, and he's not gonna sit idle and let a once in a life time opportunity go to waste. We recycle in this home.  If he's lucky, he won't make too many mistakes along the way. When reading other stories I am always shocked by how insanely powerful dungeon cores are. The things they can do, in a non magical majority setting, would be world changing. I wanted to experiment with that and see how a world would change as I played with that plot device  Most people are ok with criticism, me I am requesting it. I have no Idea what I am doing and I am willing to take suggestions.  You can expect a modern world soft magic system, some major power creep as things get going and an expanding cast of characters as the story progresses.   Daily updates until chapter ten, then twice weekly
