Black Vultures

Everyone in the group followed the student's finger only to cover their mouths at the disgusting scene. Five bodies were impaled into the stone pillars and blood still dripped down their legs. It wasn't hard to guess that they weren't killed that long ago which only spelled trouble. 

"It was too good to be true indeed," Number One commented as he only needed a single glance to know what was going on. He wouldn't be surprised if Rose has already planned that way ahead of time. 

"Everyone, retreat! We need to get out of here before the Black Vultures smell the blood!" Headmaster Blake cried out in all seriousness and lead the group back but they only managed to fly for a few hundred meters before they spotted even more corpses. 

"They weren't here before!" the female students pointed out while their bodies trembled and everyone quickly realized what was going on.
