It was late...too late to be roaming the corridors of the castle, but that is what Marguerite was doing. There was a great danger of being caught by any teachers patrolling the hallways, or that pesky poltergeist who delighted in alerting the whole castle when a student was out of bed. Marguerite's night-time wanderings were usually taken outside the castle, into the grounds or the Forbidden Forest; where she was much less likely to be seen. Tonight was special; however, tonight, she was out to steal a certain potion. She was not sure whether the castle's hospital carried exactly what she was looking for, but there were only two ways to find out, and she highly doubted the school nurse would tell her. It was too obvious why she would want it, and she highly doubted the school head would approve.
Marguerite's feeding on her newly entrusted 'Donor' earlier that night had shaken her a bit. She had the art of feeding on a living being without killing them down to perfection when she had last entertained Donors, but that had been over a century ago. She had become to thirsty for living blood recently, and she had taken too much. She had given the boy his strength back with the use of her own blood, but she could not continue to do that, lest he become a ghoul. The only other option she could see in front of her, was to steal some blood replenishing potion from the hospital wing until she fell back into the art of feeding from a Donor. She would not risk bleeding the boy too dry again, unless she had some back-up.
Marguerite arrived outside the hospital wing, crouching close to the floor, making it more difficult for her profile to be deciphered through the darkness. She had no way of knowing whether there were any students within the hospital dormitory or not. If there were, a nurse would surely be in there to monitor them. She couldn't be sure whether or not the nurse always slept in the wing. Marguerite would just have to proceed under the assumption that they did, which meant being extra quiet.
Marguerite squeezed past the heavy wooden doors and found herself standing between the two lines of beds. She did a quick visual sweep of the room. Surely, the potions would be kept in the Head Nurse's office. Marguerite approached the door separating the patient beds from the nurse's station. She reached her hand out and grasped the handle, trying the door to see if it was locked.
