Blood is the currency of all vampires, and their only sustenance.  They can ingest human food, and even digest it.  But for what?  They gain no nutrients from cooked meats or fat-injected patties.  Only fresh, living blood can keep a vampire young and strong.  Without it, they lose themselves and become little more than savage beasts, as worthless and mindless as the wolf-kin.  In Diamond City, blood is never is short supply.  But humans only have so much blood to give before they die.  And with their limited understanding of nature, humans offer little in the way of companionship.<br/><br/>That is where Tara Hemsworth comes in.  As a loyal patron of the Coven of the Thirteen Roses, Tara runs the blood house in Diamond City.  Vampires from the coven can enter whenever they desire, and indulge in anything that sparks their interest.  With more than fifty "donors," the blood house is never out of the most vital component of any proper vampiric pleasure.
