The forest at the top of the hill is illuminated by the light of a flame. A magical flame. The forces of the Inquisition rush to the scene, and find a terrible crime: a witch has killed another, of whom only her burnt remains are left behind in the flames.

Pyre, a young up-and-comer of the Inquisition, must escort the witch Sunniva, guilty of this vile act, through her last will and testament. A last journey before she too meets her fate at the stake.
