Casimir Toomes has been pretty successful as an adventurer... until he wasn't. With his team shattered and the surviving members scattered to the four winds, he went back to his home country of Anima, and at his Master's behest, became a teacher at the Academy of High Magic. 

Sure, his Master keeps bugging him to take on some personal students of his own, but he's not in this teaching gig for good, it's just a temporary thing, as a favor. 
There's absolutely no way he'll get attached to any of the brats. 

Updates on Monday.
