Death on the Reik (1987)

The enemy within Campaign, Vol. 2
From the back cover:
"The conspiracy of Chaos is still spreading its tendrils across the world, marshalling its resources and scheming in the most unlikely places. On the trail of a rock that fell from the sky hundreds of years ago, the PCs find evidence of sinister goings-on which will lead them deep into the heart of the Empire, on the way to its source. The taint of Chaos must be cut out... but first it must be found.
The second volume of the classic Enemy Within campaign for Warhammer Fantasy Roleplay, Death on the Reik picks up where Shadows over Bögenhafen left off and takes the characters on a voyage to danger as they become river-traders on the largest waterway in the Empire, the river Reik. In charge of a river-boat, they will meet traders with secrets, pirates, fearsome inhumans and terrifying mutants as they try to unravel the threads of the adventure's plot.Death on the Reik is intended for a party of 4-6 player characters. Like all the episodes of the Enemy Within campaign, it can also be played as a stand-alone adventure. The book contains all the usual pre-generated player characters, maps and hand-outs, as well as a special 16-page section on life on the Reik, and a double-sided poster map showing the Reikland and, on the other side, a painted diagram of the setting for the adventure's climax. It is continued in The Enemy Within vol.3: Power Behind the Throne."
