Its the beginning of the Year of Wild Magic (1372 DR) in Waterdeep and its inhabitants are celebrating the beginning of new year. The staff and residents of Stardust Hall, an orphanage run by the clergy of Selûne and Ilmater, are no exception.
Returning to their home after a long night of drinking and partying, the group surprises a small gang of gnomes and dwarves who are about to steal from a blacksmith neighbor. They stop them but, trusting the small thieves word that they were only acting to help their families and their promise to never steal again, the group let them go even though their friend Drudarch is against the idea.
The next morning, the Daily Trumpet, one of Waterdeep's newspapers, announces that almost all South Ward's blacksmiths have been robbed on the previous night. Strangely, only the dwarven one were left alone by the thieves. The article also mentions that the authorities think that the thefts were done by an organized group, probably the same that is responsible for a series of thefts in a few nobles’ villas in North Ward. Asking a few questions around, the group manages to identify the probable culprits: a group of burglars named the Wonder Bringers, a small non-violent gang usually operating in Dock Ward and composed only of halflings, dwarves and gnomes. Named in the honor of Gond, God of craft and invention, the small guild specialized in safe breaking and mechanical traps are supposed to be led by an rogue priest of the Father of Invention.
Following this lead, the young adventurers took upon themselves to track down the culprits and bring to justice, wishing to protect their neighborhood and correct their mistake of the last evening. After a visit to the House of Inspired Hands and a meeting with its high priestess, they confirmed that the Wonder Bringers's leader was an exiled cleric of the Wonderbringer named Nigel Cobwheel. Cobwheel was a promising inventor and cleric of the church until he sold the blueprints of traps and safes to criminals. Realizing that the high priestess would not reveal information that could lead to a loss of prestige for her church, Rhivaun suggested that the party could track down and capture the unethical priest and bring him back to face his peers' judgement. Appreciating the tact of the young selûnite, High Seeker Zulthind accepted the offer and revealed what she knew about Cobwheel and his small organization.
With the details given by the Gondar priestess and some information gathering in Dock Ward, the five adventurers discovered one of the favorite whereabouts of the Wonder Bringers and a favorite of Waterdeep's small citizens: a tavern named the Underdark. Unfortunately, the tavern was burned to the ground by criminals two months ago. Examining the ruins, one of them found a hidden safe filled with gold pieces given to the tavern's owner by Cobwheel himself. A small note attached to the gold pouch confirmed some rumours about the fact that the Wonder Bringers were actually stealing people to help their community. It seemed suddenly that this little "guild" was really doing some good in the neighborhood and protecting its small citizens from thugs like the Scarred Beasts, a racist street gang operating a protection racket and suspected by many to be the ones responsible for the destruction of The Underdark tavern.
Still held by their promise to find Cobwheel and the stolen weapons, the investigators managed to find the location of the new Underdark tavern that relocated into the Warrens, an almost forgotten ward of the city populated with gnomes, halflings and dwarves. Even though the famed Morigard Dalrak gave them the location of one of the secret entrance to the district and told them to announce themselves as his friends, the young adventurers were attacked by suspicious halfling guards but quickly calmed them and managed to enter the tight but empty tunnels. Something was wrong, the place was so silent and empty it looked like a ghost town. They soon confirmed their fear when they entered the tavern: all its occupants, from the gnome barkeeper to the customers were staring in front of them with emotionless eyes, as if their will had been sucked out of them.
Unable to help them at the moment, the group started to walk away of the tavern when the gnome barkeeper pulled throwing axes from his belt and threw them in their direction. One of them heard a small voice near the bar when the gnome attacked and a spell cast by Petyr revealed a small insect-like invisible creature flying around in the room. Even though the gnome and his bouncer were experienced fighters, the force of numbers and good tactics managed to bring victory to the group who brought back the bound fey-like creature with them out of the tavern. As they were walking out of the tunnels, they met with clerics of Garl Glittergold and Yondalla who invited them in their shrine to explain them what exactly was happening in the district.
