"Good choice." Remus nodded and thus began their lessons proper. He would take about an hour, just working through the basics of defensive spells as the light thought of them. However, it wasn't like being in class as the way Remus taught were quite different. He taught in less of a structured way, a way wizards rarely thought. His defenses were built in layers instead of a single spell. A quick layer first, building in strength so it would be ready for a bigger attack. People rarely even thought about 'wearing' defenses but, as he pointed out, that was the point. Most wizards believed they could dodge and reflect and redirect everythibg, which was important, but when one did get through... It was important to have some defenses left.
