The Black Mist (2007)

From the publisher:

PLAGUE AND NECROMANCY...
When a city is wracked by a magical plague that cannot be cured, the PCs are trapped inside the walls by the seal of quarantine. Will they hide from the threat of death? Or stand tall against the city's terror?

But whatever course they choose, nothing is ever as simple as it first appears. Death breeds death, and before this mist-born plague has passed the entire city will be placed in a crucible of riot and fire and necromancy...
