There are also intrigues here (in which the main character does not understand anything), ghosts, necromancy, wise (as it turns out, not very) mentors who die at the most inopportune moment, a strange corruption scheme, which is based There are dead horses, an insidious demon, whose replicas are printed with bold font, and mandatory universal evil.

But friendship, love, growing up and the dead are still the main thing.
