The Red Duke of Fate has invited 111 guests to a great feast at his Witch Mountain mansion, located in a desolate region of Threxas. Those guests, including the characters, are familiar with the Red Duke’s lavish banquets and luxurious abode – they were all at his summer home the previous year for a special event. At that event, each guest was given a small puzzle in the shape of a small tube and asked to protect it for the next year. If they returned to the mansion with the tube one year later, they would receive an even greater surprise gift. In the months since, some of the guests (including the characters) studied the small puzzle, determined to solve it. But no sage, no wizard, no one in all the lands could understand the glass tube’s purpose or how to solve it—or really, how it could be considered a puzzle at all! To gain entry into the mansion, guests must present their puzzle tube. Guests who have lost, sold, or given theirs away will not be permitted through. What the characters do not know is that the puzzle tube is in fact a magical and indestructible vessel that contains the essence of a great evil. At his next feast, the Red Duke plans to open all the tubes simultaneously, using their sinister contents to ensnare and steal the souls of his unsuspecting guests. The guests will have until dawn to reverse the soul-binding spell or be forever bound to the Red Duke. Servants and other guests can help the characters uncover the steps required to reverse the spell’s effects. The characters will have to explore and work together to prevent the evil from consuming their souls at dawn.
