This is what is referred to in the DCC as a funnel adventure. In D&D you start at level 1 heroes, in DCC you start with level 0....people. A funnel is an adventure where you start playing as these people and finish with....less of them than you started with. Dark trails is a DCC variant that asks the question, "What if the Civil War in 1865 was actually ended by the awakening of the Elder gods and subsequent unleashing of the horrors of Necronomicon unto the Wild West?" Come play at this table and you'll find out.
In Death Crawls West, the characters are settlers who have joined a wagon train at Fort Fallow, on the outskirts of the New Mexico Territory. Their destination lies across the badlands in a fertile river valley named Whitaker’s Valley.
The decision to move West is certainly easier considering that a Man of God has brought back samples of rich soil, clear water, and lush plants that grew in the valley. Reverend Halpern originally set out a month ago with his trusted hands to find land that will sustain and nourish those choosing to follow him for a new start in the untamed West. The settlers know the journey will be difficult, but they have faith the trip will be worthwhile.
