As Sir Kejtar's skills were evolving he realized that he reached a level where he needs to learn to hide his skills. In some of the books he read he learned that there are specific incantations that when called upon will hide his skills from those around him. To test it, he decided to visit a temple which housed the sacred flame of truth. During the hunt for those who practiced black arts, suspects were sent to face the flame and if they turned out to be mages the axes fell and killed them.
Sir Kejtar took a deep breath and went in
That was a long hallway
He felt naked - he left his armor, helmet, sword back at the camp.
