Dear Father Moran Anderson: Congratulations! Although you never smoked, you have been fortunate enough to be diagnosed with lung cancer at an age when your soul is still fresh. Unfortunately, your business of raising "Children of Hell" is not yet complete, and this Duke has been forced to invoke the "delayed death" clause. After all, these slippery little creatures are far less cuddly than they appear. Please ensure that they are regularly fed with delicious souls, whether human, demonic, or angelic. Don't forget to abide by the "Heaven-Hell Truce" and the "Exorcist Association Management Act." You wouldn't want Michael, Gabriel, and the others to know about our transaction, would you? If you have any further questions, you can consult this Duke directly in Hell. I look forward to the day when I can personally harvest your soul. ———Lucifer, the Arrogant Duke, you are trustworthy...

From a humble individual struggling on the fringes of order, he rises step by step to the pinnacle of the Hunter Rankings. Welcome to 1888, a time when SAN is as precious as bullets.
