Starting off a Dungeons and Dragons session with a mystery is a great way to engage your players and get them invested in the story. Here are three examples of how you can introduce a mystery to kick off your session:
The Missing Heirloom
--Midjourney: a missing heirloom, old victorian lady, jewels, painting, standing in an entry way of a mansion, sad look, dark, staircase rising in the back, checkered floor, ultrarealistic--
NPC Name: Lady Catherine Blackwood, a wealthy noblewoman
Class: Aristocrat
Situation: Lady Blackwood has just discovered that her prized heirloom, a valuable necklace, has gone missing. She suspects foul play, and she's hired the players to investigate the theft and recover the necklace.
Motivation: Lady Blackwood is deeply attached to the necklace, which has been in her family for generations. She's also worried about her reputation, as the theft has caused quite a stir in high society.
Cause of the Mystery: The necklace was stolen by Lady Blackwood's estranged son, who is desperate for money to fund his gambling habit. He's been secretly pawning off family heirlooms for months, but the theft of the necklace was the final straw that caused his mother to cut him off completely.
The Haunted Mansion
--Midjourney: a haunted mansion, dark, hill, trees, moss, fog--
NPC Name: Marcus Van der Meer, a reclusive wealthy noble
Class: Noble
Situation: Van der Meer has just purchased a large mansion on the outskirts of town, but strange things have been happening there. Doors open and close on their own, ghostly apparitions have been seen, and eerie noises echo through the halls. The players have been hired to investigate the source of the haunting and put an end to it.
Motivation: Van der Meer is a man of science and reason, and the supernatural events in his mansion are deeply unsettling to him. He's also worried about the effect the haunting will have on his business dealings and social standing.
Cause of the Mystery: The mansion is haunted by the ghost of Van der Meer's former business partner, who he cheated out of a large sum of money. The ghost is seeking revenge and won't rest until Van der Meer makes amends.
The Poisoned Well
--Midjourney: the poisioned wishing well, castle square, midevil, dark, empty, fog, dead tree, crows-
NPC Name: Mayor Gregory Hale, the elected leader of the town
Class: Politician
Situation: The town's main water source, a well located in the center of town, has been poisoned. The players have been hired to find the source of the poison and put an end to it before more people get sick or die.
Motivation: Mayor Hale is concerned for the health and safety of his citizens, and he's worried that the poisoning is a deliberate act of sabotage against the town. He's also under pressure to find a solution quickly, as the town's economy relies heavily on the sale of its water to travelers and merchants.
Cause of the Mystery: The well was poisoned by a rival town, which is trying to drive the other town out of business. The rival town is secretly funneling their own contaminated water into the well, hoping to make the other town look bad and drive away their customers.
By introducing a mystery at the beginning of your Dungeons and Dragons session, you can pique your players' curiosity and give them a clear objective to work towards. With well-developed NPCs, interesting situations, and engaging motivations, you can create a compelling story that will keep your players engaged and excited to see where the adventure takes them.
