The theoretical courses were all boring, so Ethan had no idea which one to decide, even how he was going to study them. However, someone appeared and suddenly gave him an option.
"It looks like you finally decided to take this place seriously," Emily said after she saw Ethan facing those papers with a serious expression. "If you are having problems choosing a theoretical course, you can choose this one, and I will help you with your studies."
The course Emily recommended was: the origin of mana. Although it seemed interesting, Ethan already knew that he wouldn't learn anything. As far he could tell, mana was an energy that always existed, and the inhabitants of some worlds only began to use it by accident. Most likely, it was an energy that appeared at the beginning of the universe. Although that was cool and all, it probably wouldn't help him in any way since it was a theoretical course.
