The novel is closest to the dark fantasy genre. Similar works, in my opinion, are “The Witcher” by A. Sapkowski, “Vampire Hunter D” by H. Kikuchi. The main thing when writing was the combination of the combat component and psychological drama. The book is set in a fictional world based on medieval Europe. The dominant position in society is occupied by the Order - a knightly organization that protects humanity from dark forces. The representative of the Order is the protagonist of the novel, from whose behalf the story is told. Key to the plot is his unexpected friendship with Orestes, a half-vampire and wandering monster hunter.
