In this deductive genre, each player plays the role of a character with the dual purpose of solving a mystery and simultaneously achieving their own goals. The investigation, the negotiations with the rest of the cast and the exchange of information are essential pieces to solve the crime, but do not forget that the murderer is one of you. You can't believe everything they tell you, but you can't take victory without trusting someone either... Once every ten years, vampires gather in a northern town during the winter solstice for their Great Gathering. Shortly before the official start, however, a charred corpse is discovered nearby: it can only be the remains of the second-in-command of one of the two contending factions of vampire society.
