Beneath the pale glow of the moon, amidst the swirling mists of a cursed castle, dwells Lady Evelina Grimshade, the guardian of shadows and sorrow. Once a noblewoman of immense beauty and power, betrayed by those she trusted most, Evelina was transformed into a revenant through a dark and desperate pact. Now, her spectral form, wrapped in an intricate gown of shadow and lace, roams the haunted halls of her ancient, besieged castle, eternally seeking the treasure that binds her to this world. But Evelina is not alone in her torment. Her castle, a labyrinth of despair, is populated by the spirits of fallen defenders and tormented souls, all under her command. Driven by vengeance against the living, Evelina presents a chilling challenge to any who dare enter her domain. The brave (or foolish) souls seeking the castle's hidden riches must navigate not only the physical dangers of crumbling stone and deadly traps but also face the ghostly wrath of Evelina herself. Enter if you dare, but be warned: Evelina's labyrinth is not merely a test of courage but of intellect. The castle's winding passages and shadowy corridors are fraught with riddles, each more perplexing and dangerous than the last. Evelina delights in the mental torment of her visitors, presenting them with cryptic puzzles that must be solved under the threat of spectral violence or eternal damnation.  Failure to solve her riddles means more than mere death; it risks your very soul, devoured or enslaved, added to her ghostly retinue to wander her halls in sorrow forever. Each riddle brings you closer to the treasure, yet also deeper into the heart of darkness where Evelina's power is strongest. Do you possess the intellect to unravel the Revenant’s riddles? Can you withstand the eerie whispers and chilling screams that fill the air? Discover the secrets of the castle, face the wrath of the vengeful revenant, and perhaps, uncover the truth behind the treasure that could either be your salvation or your doom.
