Also, if you’re wondering what he was doing. He is casting a common spell among people that so much as dabble in magic. It is a low energy spell that just delivers a letter to a person. Most times it requires either a personal item from the person, or at least extensive knowledge of the person. One can also send a letter by using a map and pin to send it to a certain location.
Just a bit of flavor for a spell that exists in my world.
