Working as the right hand man to Death themself is a pretty big task. Especially since this was one of the Ghost Rider-type bargains where you maybe made a bad choice in a desperate moment and now the rest of your miserable life is spent doing supernatural dirty work. In Death's Gambit, that dirty work is taking down the immortal guardians of Siradon, who have been acting really cocky in the face of their resistance to dying. Purging their souls won't be easy, but you're a pretty capable reaper.
