The Flying Misfortune

Publisher's blurb:

This adventure is designed for the Storm King’s Thunder campaign, and is meant to enhance your party’s connection to important events and NPCs. While it is intended for a party of around 6th level, the nature of the quest is such that it fits easily with a higher level as well. It will put your players in contact with Felgolos, the bronze dragon that is encountered in Chapter 9 of Storm King’s Thunder, as well as the ancient dragon Iymrith, who plays a prominent role in the main plot.

Of course, you can also change names and locations to make this adventure fit into any other campaign world – as long as it has dragons and deserts. Enjoy!
