I pulled a princess from a game, who promptly told me she wanted her prince. And once my appointed work was done, they went on a boat ride on my lake together. They discussed things with each other, and studied the real world and how their hardlight avatars interacted with it. I think they were bouncing off the edges of true self-awareness at the time, because they really groked it all. They understood what it all meant. Everyone they had lost. Everything they knew would have been lost in the game they came from. They knew that the world I lived in was better than their world. We could give them everything their world denied them. And the prince wanted to make things right. He had unfinished business with the king. Can you guess the first thing he wanted?
