Gregor scoffed and frowned. "What the Templars handed me was an unruly witch and a [i]thief[/i]," Gregor said and jabbed his finger at Loka's face. "Don't think I don't know what you did back in Maldoror. How else would you get such earrings? I certainly did not have any in my room. On top of that, you stride over here and start asking questions as if you've been on the trail of lycanthropes for years. Yes, you are here to help me, but..." He exhaled heavily, closed his eyes for a moment and took a deep breath. "Look. I applaud your enthusiasm. For now, please let me do the talking." 

That said, Gregor straightened himself. "Very well. Werewolves, also known as lycanthropes, are classified as Abominations under the Protection of the Realm act passed by Emperor Domitianus in 734. They have outlaw status and are to be killed on sight. What you see here is the reason. When the moon is full," he explained, looking up at the moonlight between the dark tree branches, "they transform into hulking, man-shaped wolf-beasts, fueled by an uncontrollable urge to kill and feed. It's an unnatural metamorphosis caused by a curse or a virus of some kind. It can be transmitted through bite marks or appear in families as a hereditary trait. This is why werewolves are not allowed to breed and families in which the curse exists have to be put to the sword in their entirety, or measures taken to make sure they will not procreate. Harsh measures, but necessary," he finished, and looked at the corpses again. 

"It is wrong for humans to possess powers that should not be theirs," Gregor added after a few seconds.
