Annalyn uses her Sanctuary to provide free healing to the populace. Gwyn uses her Arcane Study to craft a book to sell, netting 10gp. Both have their Libraries on hold to look up stuff. Meanwhile, Mark uses his Storehouse to sell 244gp worth of goods, netting 24.4gp, which he keeps. He then uses his Garden to sell some “herb," making 50gp.
It's the rainy season. Torrential downpours happen regularly and often all day and night. In the morning, the party is contacted by Arbale of Arbale's Curios, a magic item collector. One of his artifacts, the Finder's Fee, has been stolen, and he seeks the party's help to find it.
After a long, grueling day of pursuing leads in the rain, the party finally tracks the thief down to a small, modest house in Dod's Center, a neighborhood in the Bowl. Mark has cast locate object but feels no sense that Finder's Fee is in the area. They speak with the owner, an older human man, who chews their ear off. As he goes on, Mark notices out of the corner of his eye a darkly-clad person sneaking out from the back of the house. He and this person lock eyes for a brief second—and then the thief flees into the bustling chaos that is the Broadway!
The party pursues! Mark immediately wildshapes into a wolf and rushes into the street, with Annalyn and Gwyn following. Annalyn casts find steed, conjuring a great celestial horse, and Gwyn uses misty step to bamf herself onto the horse. Gwyn uses a sorcerous burst to severely injure the thief, but he is undeterred. The thief is fast, but our party is faster.
As they close in on their quarry, Annalyn shouts a command at the thief: HALT. It works, and the thief slows to a stop. Annalyn grapples him while Mark quickly uses his Shiftweave to assume the appearance of a Constable, convincing the crowd that this is some sort of police action. But after the command wears off, the thief snakes his way out of Annalyn's grasp (pun intended) and whistles for help before being knocked out by the dwarf.
Mark uses his second wildshape to conjure his familiar, Slag, who surveys the crowd. Gwyn surveys as well as Annalyn pats down the subject, recovering a small, crudely made lead box with a locked clasp. She also notices that the thief is a yuan-ti man, pureblood, maybe barely out of his teenage years. As the crowd gawks at the scene, Gwyn notices a snake slither through the legs of the onlookers. The snake quickly shifts form, becoming another yuan-ti with goddamn SNAKES for arms. Help has arrived.
