The town of Saint-Lys seemed peaceful at first glance, with streets lined with old stone buildings and green parks where families strolled on Sunday afternoons. But behind this idyllic facade hid a deep darkness, a latent evil that was only waiting for the right moment to manifest itself.

Saint-Lys had a long history of unexplained tragedies and mysterious disappearances. The ancients spoke of curses and forgotten creatures, stories relegated to children's tales. But to those who lived in the shadows of the city, these legends were very real.

Lucas Moreau, police inspector, was one of the few to know the true nature of Saint-Lys. With his graying hair and piercing gaze, he bore the invisible scars of many perilous investigations. Moreau was not an easy man to pin down. A loner by choice, he had dedicated his life to pursuing evil in all its forms. His unorthodox methods had earned him both respect and contempt among his colleagues.

Born in the slums of Saint-Lys, Lucas grew up surrounded by violence and despair. Her mother, a pious woman, had often spoken of dark forces, presences that she claimed to feel in the family home. Lucas had initially dismissed these ideas as superstitions. But over the years, he had had to face the facts: certain things escaped logic and reason.

After joining the police, Lucas quickly made a name for himself thanks to his extraordinary intuition and his unwavering determination. His colleagues nicknamed him "the bloodhound" because of his ability to ferret out the slightest clues. However, this reputation came at a price. Lucas had lost friends, relationships, and had often flirted with the fine line between justice and revenge.

One winter evening, as the wind howled through the narrow streets of Saint-Lys, Lucas received a call that would change his life forever. A body had been found in an indescribable state, a crime scene that seemed straight out of a nightmare. When he went to the scene, Lucas didn't yet know that he was about to dive into an investigation that would reveal the city's dark secrets and test everything he thought he knew.

Saint-Lys was about to reveal its true face, and Lucas Moreau would be the only one who could prevent chaos from taking over the city. But at what cost ?
