Like Curse of Strahd’s Appendix B: Death House before it, Wizards of the Coast has provided A Great Upheaval (Chapter 1 of Storm King’s Thunder) for free on the Dungeon Masters Guild. Like Death House (which advanced PCs to level 3), Chapter 1 is an optional part of the adventure aimed at advancing players to the level 5, the starting level of the main adventure.
The somewhat printer friendly PDF includes…
- 22-page A Great Upheaval adventure
- Tressym (mischievous winged cat) from appendices of Storm King’s Thunder
- D&D Adventurers League Adventure Logsheet
