"I think I see," he says, nodding. "It's like you're programming. Only instead of on a computer, it's the world. You're telling the world what to do, and it...does it."

His hand goes to his mouth, thinking. If he knew more, he's sure he could put them together, chain them to tell a story like Tony had said. After all, what's programming but telling a story, telling the system what you want it to do, and how and when and why? These sigils seem to work the same way, for the world. The world!

Oh, the possibilities.
