In the small hamlet of Riverbend, the miller’s wife is missing, and the locals suspect the husband himself was involved. But all is far from what it seems. Ellessandra, the missing woman, is actually an elf from the Summer Lands. She came to live in the human settlement when the miller made a dangerous pact with the River King, the lands’ powerful sidhe ruler. Now, the player characters must unravel the truth behind Ellessandra’s disappearance, piece together the involvement of a young fey lord, and dive into the fey courts of the Summer Lands to stop a raid that would surely spell Riverbend’s doom. All the while, Arthurian intrigue and mischief runs high among the fey lords and ladies in this mercurial, open‑format adventure from acclaimed adventure designer Wolfgang Baur!

"The Riverfront Rat Gang" is a ratfolk lair, also featuring wharflings and a doppelrat, designed for five 1st level characters. This adventure can be completed in one session. The old dockyards once served as the primary center of commerce in town. Years ago, political pressure from an influential merchant who wanted the docks to be loser to her business forced shipping concerns to move their docks upriver. The new facility accommodates larger ships, and the old docks fell into disuse. Talk of converting the property into a set of riverside shops died when a rat infestation proved to be an unsolvable problem. Thus, the old dockyards have been decaying for years. This situation suited a former thieves' guild member, a ratfolk rogue, named Matimer Creel. A botched robbery (for which Matimer blamed his accomplice) turned the guild against Matimer, who fled from certain death at the hands of the guild master. He hid out in the old dockyards, confident that not even guild members bothered to go there. From there he began to exact revenge against the guild by ruining its plans or stealing directly from it. He also befriended the rat population, thanks to a golden rat's tooth he acquired, and the vermin help with his schemes. A trio of rat-like wharflings and a doppelrat, washed up on the riverbank near the docks, have joined Matimer's retinue.

The spire has existed for as long as locals can remember. Rising above the sand near the ocean, the spire is topped by a natural cave system. Stories about the place circulate around the docks and taverns of the nearby towns—dark tales of ritual sacrifice and the worship of long dead gods of lightning and storm. Many claim the victims of the old cult still crawl through the tunnels accessible at the peak of the spire. Others say a new scaly threat now lairs there, and the storms of late have been most violent near that place. In this explorative and perilous adventure, the party ascends a great rocky spire to face the place’s past and the blue dragon that presently resides there.

"I was taken by the evil dogs while camping near Agav's bog. They dragged me into their lair, and it wasn't until I escaped that I knew the truth of the place: a great and bony wing buried in the side of a hill. They chained me in the dark with a candle made from foul wax and forced me to dig at the marrow. Their bonds were poorly made, and I fled several days later while they slept. What purpose did they have in mining that marrow? I cannot say..." The Marrow Mines are dug in and around the fossilized wing of an unnamed leviathan. A small pack of kobolds lives and works in the mines, which are heavily trapped. The kobolds defend the area fiercely and patrol the region around the mine. At night, a handful of urds make aerial surveys of the territory. The urds live in the deep reaches of the wing's tips.
