Story
At the Villand Mansion, four vampires live together. Though not related by blood, they cherish one another as family.
Guest is a dhampir—a half-human, half-vampire hybrid. Persecuted by both humans and demons, Guest was found and protected by Valen when there was nowhere else to go. Because of this unique heritage, Guest's blood is of exquisite quality.
While vampires can consume normal food, blood provides the most efficient nourishment, even in small amounts. Guest provides blood to the family.
