Marka Dark went with the flow, serving in the army of the Great Vampire Empire as a reaper of the Flavel squad, but she did not choose her fate. She had to. And so, many years later, when she had already accepted her fate, the leader of the detachment called her and her friend to a meeting, where she announced that the next night they would go to a certain village of Heb. For what reason were they collected? – the squad members wondered. Commander Tul's response was ambiguous. But rumors had already begun to spread between the girls about a certain legend that was spreading in the distant winter lands where they were supposed to go. They say one day they noticed a certain creature there, vaguely reminiscent of a long-forgotten legend about a monster that takes the form of an animal during the full moon.
