"Train randomly gives out points for doing chores, participating on missions, and whatever else it feels like." It would probably have helped if he explained the missions part first, but oh well. He would have gotten there eventually. "The train goes from world to world and we help out with whatever crisis they're having. So basically what we did at home, but it doesn't involve - nevermind. I think people have died on the missions."

In other words: exactly like what they did at home. Hopefully with less dead Welsh kings, though.
