You've seen what I can do. I close rifts, so I suppose in that way I'm a tool. But I'm also real. The tablet is just a way to show me to you. It's like if I wrote you a letter. The letter shows you what I've said, but the letter isn't a real person. I'm real and I'm talking to you on my own tablet. But if we can figure out a place to meet, I can show you I'm really here.
