Summary:

The Grims are just another name for the outside world. This is one of the things that Elyot Orleck learns when he first arrives in Seolfor Palladium, a magical city hidden deep in the mountains. Elyot is promptly enrolled in magic classes, and to help him keep up with the others, he is assigned a mysterious tutor by the name of Monty Bounder. What begins as a formal arrangement between student and superior soon spirals into something far more complicated, much to the chagrin of Elyot’s friends.
