Lullaby of Demonia

As a merchant trading in interdimensional artifacts, you've garnered an eclectic clientele in your travels—one of whom just so happens to be the Emperor of the Demonic Astral Plane himself, Lucifer! When misfortune strikes and you're forced to throw yourself on his royal mercy, he has a proposition for you—work as custodian of his vast collection of relics in exchange for refuge and a means to earn your freedom. The only catch—you also have to serve as personal maid to his four capricious sons, the Princes of Pride, Greed, Lust, and Envy. As you adjust to life in a palace ruled by sin, will you be able to resist temptation when the princes vie with each other not just for your heart, but for possession of your very soul?
