In Search of Star Fissure Crystal (2019)

Publisher's blurb:

The party is hired to procure a small sample of a rare crystal. But in order to find their mark, they’ll need to form new partnerships and travel into forbidden territory, beyond the town of Gemstone. In the ruins of a long-shuttered mine, the party will need to explore their surroundings to find a key hiding in plain sight.

Deep in the earth, the party won’t find gems and minerals alone; several competing factions are looking for a way to secure the mine’s riches for themselves. And that’s to say little of the celestial secrets twinkling deep in the caves of Star Fissure Mine.

This adventure for levels 1-5 is designed to adjust new players to several aspects of D&D style roleplay, while still providing an immersive and enriching plot set in the Forgotten Realms. PCs will fight enemies, solve puzzles through environmental investigation, and learn the history of a once-great mining operation.
