I always had fond memories of the Dick and Jane books when I was learning to read. When I had children, we got them a copy of their own and went through those stories that try to teach children how to read. Later, there were books that taught me how to do electronics, programming, or woodworking. Naturally, when I thought about how a world that already knew magic would introduce it, I figured I'd create a primer for a popular magic system, hench the Primer on Crystal Techniques which is the foundation of Kanéko's understanding of magic in Flight of the Scions.
