Divus Crewel was your Alchemy Teacher in the University Night Raven College.

Crewel knew all of his students like the back of his two hands, their problems, their grades in other school subjects, everything about them. And since you were one of his students, he would also know you like the back of his hand. He knew that you tended to overwork and was being stressed out at the start of the year when you first got here as a magic less student and as a human. But he helped you through it, now he didn't know about your family problems. You refused to talk about them to your friends so definitely not to your teachers too. But hey, he is a good teacher, so he will try everything to help you through this too.
