Curse of the Long Night: A 3rd Level Adventure for 5th Edition

Torsick the Mad once ruled over these lands from his subterranean hold, the Undercastle. Eventually, his insanity consumed him and he slew his court and all those within his home. His dark spirit sealed off the Undercastle from outsiders and, as time passed, he fell from history into myth and legend.

The nearby hamlet of Redstone, so named for the mine that the settlement sprung up around, slowly grew into a proper frontier town in the decades since. All was well until once day the sky darkened and a rolling cloud blanketed the region casting it into an endless night. Unbeknownst to the townsfolk, the spirit of Torsick had awakened and now seeks to gain dominion over his realm once more. From the halls of the Undercastle, he sends forth an army of undead to plague the land. If no one stops him, eventually Redstone and the lands around it will be overrun.
