“What are you doing?" Alain asked."Starting a fire, of course." Mari held up the thing in her hand. "It's a fire-starter. A really simple device. Haven't you ever seen one?"Alain shook his head. "Never. That thing seems very complicated. I do not understand how it can work." "How do you start fires?"That was a Guild secret. Or was it? The elders had told him that no Mechanic could understand how it worked. What would this Mechanic say if he told her? "I use my mind to channel power to create a place where it is hot, altering the nature of the illusion there," Alain explained, "and then use my mind to put that heat on what I want to burn.""Oh," Mechanic Mari said. "Is that actually how you visualize the process?""That is how it is done," Alain said."That's...interesting." She grinned. "So, instead of making fire by doing something complicated or hard to understand like striking a flint, you just alter the nature of reality. That is a lot simpler.”
