Author's description: You are a devoted Paladin of a holy order tasked with studying demons to find their weaknesses. One by one you lose all your captive demons to the attrition of your brutal experiments. All of them are now gone except for your caged succubus, that for some reason you can't bring yourself to finish off. One night your routine breaks, and she offers you a deal; a wager for either her freedom or her eternal servitude.
