For some reason, it always came back to the sky for him. It might have had something to do with his mother's fascination with divination or simply the fact that he was named for one of the constellations. Regardless, looking at the sky reminded him of how small he truly was in comparison to everything else out there and that, regardless of the stress of his problems, worse things have happened. Draco looked up again, staring off at Scorpio and naming the stars within the constellation.
He was staring at one, struggling to remember the name his mother had given it when it disappeared quickly before suddenly reappearing. It was as if something large had flown in front of it. Draco slowly scanned the sky, watching to see if it would happen again. He knew there were large creatures that lived in the forbidden forest but most flying ones would be asleep at this time of night. Luckily, the moon was full which shed some light on school grounds. Draco had nearly given up and was about to turn in for the night, obviously seeing things that weren't there, when it happened again, only this time it had blocked light from a series of castle windows. Draco waited and watched for another twenty minutes before finally giving up on. It wasn't in the cards for him to see the creature again tonight.
The following night, Draco returned to the Astronomy tower, per usual, after a long evening in the Room of Requirements. He had spent the entire day there, being a Sunday. He had been going through advanced arithmancy books, hoping to find something that would assist him with fixing the vanishing cabinet and had finally decided to call it quits around ten. He scanned the sky, hoping that the creature from the previous night would reappear. There were clouds scattered throughout the night sky and Draco thought that would be a hindrance but when he did finally spot a large figure in the sky, he was actually able to keep track of it. He couldn't make out any details on the large black mass moving fluidly through the sky but he could tell it had a large wingspan in comparison to its body length. It seemed as if the creature was just enjoying itself on a flight, possibly stretching its wings.
Every night for a week, Draco returned to the Astronomy tower after exhausting himself in his research for the vanishing cabinet and every night he would spot the figure flying through the sky. It wasn't until Tuesday night that Draco realized he might be able to get a better view of the creature if he himself were flying. He brought his racing broom with him that night and waited until he caught sight of the figure before mounting it and taking off. Just like when he would finally catch sight of the golden snitch, he fought to maintain sight of the figure. True the figure seemed to be huge in comparison to the snitch, but it was nearly pitch black at this time of night in the country side. He had gotten within a dozen or so meters of the figure when it must have heard him. The creature curved up and disappeared.
Draco turned his head in all directions and sat frozen on his broom for nearly ten minutes before finally heading back to the astronomy tower. He must have scared the creature off. The weird thing was though, when he finally got a close enough look at it, the body seemed to be human.
Little did he know that the creature had taken a spot in a line of gargoyles along the castle's roof. She watched him as he wildly looked around, trying to spot her. She was lucky that she had finally realized she was being followed. Apparently she had been far more careless than normal and had been caught. And of all people to catch her, it had to be Draco Malfoy. Who knew what would happen if he realized her secret. He'd probably go to the ministry and report her, or worse, he'd use the information against her and she'd have to reveal all she knew to him to keep him satisfied. And even if her friends were wrong, like she thought, he was still the son of a notorious death eater and the information that he could get out of her would destroy any hope in the war.
The girl crouched on the edge of the roof for another thirty minutes, making sure Draco had given up on finding her. She was going to have to stop flying for a while, hopefully Malfoy would give up the chase and she would be safe. He tended to get bored easily, or rather his reputation suggested as much. She quickly glided down to the ground and cast a concealment charm on herself before slipping through the main doors of the castle and making her way to her dorm for the night.
