Publisher's blurb:
In a Bitter Rivals adventure, the player characters will be called upon to compete against an adversary that is their equal in nearly every way. The nature of the competition can be nearly anything, but is centered on the types of abilities and challenges that the PCs are meant to be the best at. During the course of the adventure, they will have to not only do their best, but find new ways to do better than their rival. By the end, they should not only win, but feel a new sense of empowerment.
