In an era when witch-hunting was considered a civic duty, the immortal executioner Heinrich carries out his orders — among them, the beheading of a witch named Gretchen, on the command of the game's villain, Dr. Faust. Gretchen is resurrected and binds Heinrich to her will as her servant. Now the two must cooperate: Heinrich's immortality keeps them both alive in combat, while Gretchen's magic is their primary weapon — and their only path to stopping the supernatural horrors Faust has set loose across the land.
