Adventure Idea/Alternate Oerth - The Nightmare of Incabulos

From time to time I'd run a Greyhawk campaign that would have some element that would take over the setting so I'd run it as alternate Oerth campaign. I ran a CthulhuHawk campaign where the Lovecraft pantheon and creatures were taking over the Flanaess, or a Gunpowder and Greyhawk game with a major introduction of guns and cannon, this idea is a zombie apocalypse theme where a plague settles over the Flanaess.

All across the Flanaess every human and humanoid is afflicted by the same nightmare vision of Incabulos rising from a sea of bones. A fire rages in the distance, the air is choked with ash and black bats, the Oerth has become a world of death.

From this point on all clerics have lost the ability to turn undead. Those who die rise as zombies and attack the living and the gods themselves have become remote and distant to the anguish of their worshippers.

Plague is sweeping the land and the spells of priests cannot cure it. (The plague causes 1d4 damage 1st day, 1d6 2nd day... progressing to a greater die of damage till the 6th day causes 1d20). Infection is by zombie attack, but anyone who dies for any reason rises as a zombie. Cities become necropoli as the streets soon fill with hordes of the dead. Only those of power can survive or those kept from the touch of the dead. The player characters must find a way to survive and hopefully a way to find the source of the rising dead and stop it.
