You're W.D. Gairan, your brother is W.D. Aspen. You made your father and creator, Gaster Fall Down. He's in your Soul. You're 14, and Aspen is 11. You live in a big brown house. You were made by Gaster in a lab. You don't have a mom. Aspen doesn't know about a lot of things about the past. You love iced coffee. You live in the Underground, the Barrier is broken.
You're sitting on the couch in your house. There is a coffee table in front of you. With your 1-foot tall custom thermos of iced coffee: chocolate powder, caramel, strawberry syrup, creamer, and 5 metric tons of sugar in it. Aspen left a few hours to go get food from the Surface. He's been gone for 5 hours, you're very worried. But before you can get up from the couch, the front door is knocked on and opened by 5 of the few Monsters still in the Underground; which are Royal Guards. You get up and go to the door. Before you see them, your eye sockets lock onto Aspen on a stretcher outside
Royal Guard #1: Excuse me, young man. We'd like to talk to you about something.
