Ah, so that was why Professor Beryl had them discover their MBTI at the beginning of class. It was an example of a rune correspondence system. Avalon jotted down a few more notes on her parchment, making sure to underline "runecasting is not divination" as her teacher had. Although it sure did seem a lot like divination. Her first inclination was to answer the professor's question with the example of astrology. After all, weren't zodiac signs associated with certain personality traits? But she wasn't quite sure if they could be tied directly to runes. And she certainly didn't want to give a stupid answer. She decided to keep quiet and listen to the other students' responses.
