Necronomicon: The Vileblood (Patreon)

You have made a pact with an ancient vampire, a  creature that has lived for centuries sustaining itself  from the blood of hundreds if not thousands of  mortals. Through this pact your patron’s stagnant  blood is infused with your own. With this hungry,  old, and vile blood coursing through your veins you  can feel the immense power your patron can  bestow onto you for your loyal servitude. Mortals  that have the Vileblood gain many vampire-like  abilities, can manipulate blood, and conjure the  wrathful spirits of those whose blood nourished  your patron’s immortality. You are not the first and  you will not be the last mortal bestowed with  Vileblood, but all the afflicted will feel its hunger.
