"It seems that there are some things a woman of Irori will find difficult to grasp no matter how long she lays with a man of Abadar."
"Your value is not something intrinsic to yourself, Carissa Sevar. Your soul's price is not something you gain by your achievements. It's what others expect to gain from you only if they pay, when they bid on you, and what they already expect to obtain they have no reason to pay for."
"You could, perhaps, sell yourself to an Infernal Duke, of Dis. And to that Infernal Duke, your value would not be any service you've done for Asmodeus or any victory over Irori that He gains. It'd be the prestige they gain by being the Duke alone in Dis who holds Carissa Sevar's soul, a prize that obviously their rivals would have gained for themselves if they could."
"I have no rivals. No matter who in Dis holds your soul, they answer to Me. The contract devils here in My domain are not Asmodeus's agents to reimburse a soul for services performed to Him, they buy souls for themselves and to profit from them. That Cheliax exploits this institution to also make those slaves more useful to their governments is not why the devils do it, any more than Cheliax is selling us souls for our devils' benefit."
"If you harbor any hope of reimbursement from Asmodeus for delivering a hundred planets to Him, who made Barbatos an archdevil for delivering but the one, you'd best compact with Him while that prize still lies within your hands to withhold. Once He already holds it, He'll see it as but His due, from His slave. He'll ask you what more He'll gain from you than He would have had elsewise, does He compact with you; and whatever that is, He'll not offer you any more than that, whatever your past services. Barbatos delivered a whole planet of souls to our Lord, but He compacted with our Lord first."
"What's your value to Me, Carissa Sevar? What will I gain that I would not elsewise have had, by owning you?"
