Chapter 71: Lord of Ditrayn

During the wedding a few days ago, Katheryn fought with that knight who was with Vaises. During the time of the match, Vaises watched her movements, and, looking at her closely, he could tell that the other knight was not able to withstand her strength. By their standards, she could be a highly skilled knight. Normal knights were trained in an academy for a period of four to six years. To become a knight, one must attend the academy and pass through all the years of training. She had the potential to become a master knight, one who could completely defeat a skilled and trained knight. She was a natural, and it was clear to Vaises that she had something special.

After the training, they join the ranks of the military.

Katheryn surely hasn't gone through any kind of training, as she lacks the form. It was definitely her raw strength that made her win.
