A gothic mystery set in the 19th Century, Castle Dornstein is a point-and-click adventure game that follows Hemlock, a young scholar hired to translate a mysterious medieval book known as The Devil’s Diary.

Written by a monk named Gregorovitz who went mad and renounced his faith, the legendary book was lost for centuries until Lord Fiodor Dornstein discovers it.

Lord Fiodor invites Hemlock, an expert in Medieval Latin, to the Bohemian countryside to stay in the crumbling Castle Dornstein as he translates the book. When the book goes missing on Hemlock’s first night at the castle, everyone becomes a suspect and Hemlock must explore a castle where secrets hide in the shadows and a dark history waits to be discovered.

Solve puzzles as you search for clues and explore the many rooms of the castle. Travel to the nearby village of Krkanov, where gossip about the castle points to an ominous past. As your investigation continues, you begin to unravel a mystery much greater and far more disturbing than a stolen book.
