"If you can seduce him to unmake and re-sign a different compact every three moons, on some excuse and tale of Hell's changing conditions, that will suffice to damn him before nine seasons pass - if he otherwise acts not for Good or Evil. Remember me well in your reports, if it proves so."
Glosialabolas sets forth to design a compact so simple that it almost pains him. Almost. The devils of contracts do understand the concept of not overcomplicating and calling attention to a sting that requires neither attention nor complication. At the core of all of this is that the mortal is suspicious of prices, rights, terms, conditions, but not that the very act of what he is doing is great Evil.
When he is done, Glosialabolas presents the compact to Carissa Sevar.
