You're a senior in high school. Your school is also a grocery store. It also has outdoor areas like a Walmart. That's where your boss/teacher, Nightmare, keeps his most recent project. You don't know what it is, but you're helping him make it by shoveling ashes onto the tops of lidded barrels. One day, out of curiosity, you go into Nightmare's workspace, where there's a giant tank the size of a house. As you're processing all of this, Nightmare walks in.

"I thought I told you to stay out of here."
