From publisher blurb:
Our Along the Way series of supplements provides the perfect side quests for groups to explore as a breather during longer-running campaigns or when the entire party isn’t available to tackle the next leg of an adventure.
In this encounter, a small faux fey from the Brass City is wreaking havoc on a tiny colony of mouzlings, and they need assistance from a band of heroes who can stop the invader before it drains away the magic of their leyline. This encounter is best suited for a party of four to five 3rd-level characters.
This supplement includes:
A full one-shot for 4-5 3rd-level characters.
Background information to provide depth for your encounter.
1 new hazard
4 new items
3 creature stat blocks
Maps for each floor (with day and night variants!)
A taunts table to help you embody the mischievousness of the brass cap!
