Drarry (vampire)

[Went to an AU generator for this one and got monsters and creatures] Story: Harry was making his way down to the dungeons where Snape's potions classroom was. Ron had forgotten his textbook down there, and, like a good friend, he went to retrieve it. However, when he got down there, he was attacked by a hungry vampire who began to feed itself with Harry's blood. Meanwhile, Draco was just roaming the halls of Hogwarts, hungry, due to the student who always volunteered to be his blood bag currently in the hospital wing. As he's walking, he seems Harry and his hunger took over. He follows Harry into the empty classroom and attacks him, drinking his blood until Harry passes out from blood loss.
