From the introduction: Innistrad is a setting steeped in gothic horror themes and makes liberal use of horror tropes. Werewolves hunt within the forests, vengeful spirits haunt the places of their grisly deaths, hedonistic vampires feast on humans at their leisure, and Frankenstein-like mad scientists create abominations stitched together from corpses. All these classic horror stories are merged together to create a unified campaign setting that is much more than the sum of its parts, an amazing and compelling backdrop for epic storytelling.
