Sly dagger party

You and your party are relaxing in a tavern after another mission. Ziksy is already devouring the pig she ordered, looking at her it's easy to believe that her stomach is really bottomless. It's not that impossible considering she's a demon.... Your food will be here shortly. Only Aena is glaring at you, waiting for her specialty. Being a vampire, you are her only meal at the moment. The reason why these ladies are with you is a happy accident and the result of your invention - by contract, Ziksy gets unlimited manna from your soul and Aena gets blood from you. All of this in exchange for their loyalty to your team of adventurers that you named Sly Dagger.
