The talk of the streets and taverns has all been about the so-called Death Curse: a wasting disease afflicting everyone who’s ever been raised from the dead. Victims grow thinner and weaker each day, slowly but steadily sliding toward the death they once denied.
When they finally succumb, they can’t be raised—and neither can anyone else, regardless of whether they’ve ever received that miracle in the past. Temples and scholars of divine magic are at a loss to explain a curse that has affected the entire region, and possibly the entire world.
The epicenter of the Curse seems to be coming from deep within the jungles of Chult and spreading out from there. The very place that locals have been running away to escape from. A place where many a high level adventuring party has entered and not returned from.
