I have a cycle of books that would be a great endeavor for people that use historicism. The Inheritance Cycle by Christopher Paloni incorporates fantasy with actual information on medieval punishments, military tactics, armor, and sword making taken from how the medieval countries would produce them for their soldiers.
In the third book of the inheritance cycle a guy named Roran( Eragon’s Brother) disobeys his captain’s orders and takes 50 lashes. The other option was to take 30 lashes and leave the military. The very last punishment is one used more often than not is to be hung. The hanging was the most used method for this type of punishment at the time to instill fear in the ranks and make them listen.
Secondly, the armor making is described in these books on a few occasions. The instructions put in these books were used by Britain when sword and shields were used. It would describe taking the mail armor and how it was made ring by ring. It also explained if you did not link the metal fast enough you would have to reheat the metal.
Then comes the sword making. In this book it tells you about the Japanese art of sword making. Swords made in this fashion were extremely valuable and took 24 hours of work to create it strong and durable. These swords were only given to high ranking officers. The swords were given to people in ceremonies of great importance.
In conclusion the Inheritance Cycle is a fantasy book series with actual historical knowledge on the making of armor and swords and battle tactics that were used and have been used, and the punishments used in medieval times.
