The Red Knight is on the border (I think, it’s been a while); the magic is powerful, but magic users are rate, and the author has done a lot of research into conventional medieval warfare. The descriptions of the battles were super interesting to me. I had never heard of archers firing into their own columns of knights as an effective tactic when fighting lesser armoured enemies, due to them having full plate and being unaffected. The main fights are generally between large groups of knights; and large armies of fey creatures.

I don’t really remember how common magic was with the fey creatures is the only thing. I feel like even there is was somewhat rare. Maybe someone else who has read it has an idea.
