Chapter 3: The Jewel Game, part 2: Valdas Manor
The PCs' acquaintance Tjeli offers them a deal: she knows where to find more "black stone" jewellery, to swap out with the Obsidian God's mirror. She leads the party on an artifact-finding expedition to Valdas Manor.
Upshot: Valdas Manor seems to have fallen partway into the Feywild, and is now home to a number of weird creatures.
