Istredd has never been afraid of his power but he has been around plenty of people who were. Some were better suited for magic than others, and the life that the mages were meant for. There was always overhanging fear of a kind, not unlike what exists in Thorne, for the mages who couldn't cut it usually didn't make it out. But magic itself? He's always loved it. It was the only thing he had.

But he is very patient for the fears he sees in others and if they were in a different situation he might have offered to help soothe some of Wilhelm's fears. It is easy for him, but if this is going to get anywhere, he has to learn how to do it on his own. Use the magic and self-soothe.

"Good, Wilhelm, you're doing well. Keep reaching. Bring it to you like you have an invisible leash around it."

Another time his advice might be different, and he is smart enough not to tell him to calm down. Lucifer has pointed out before that never actually makes people calmer. Instead he is supportive and reassuring, sustaining the flame so Wilhelm can manipulate it.

"You are safe here and you can do this."
