I was tasked with watching the area as there have been disappearances, men have been disappearing, families torn apart. The knight captain appointed me to investigate because I am the only knight with rogue skills. This issue made it all the way to the king himself, especially when his oldest son became one of the victims. The king quickly made this a priority, a few knights found prime hidden locations where nothing was left but blood. Magic barrier stops beast, something more human, we're certain. Vampire, no, they're cleaner than this, unless they intend to rip you to shreds, they may be more messy than this and leave more than blood spilled. I lead this investigation and I know these attacks happen at night, perhaps late into it.
There's few to no witnesses, although some have heard the attacks. We report through special short range communication magic. One of the men noticed late in the evening a woman walked around, and seems to have been seen doing so until the taverns close. They've watched her around the market, the taverns, and she's spotted around nearby roads to nearby homes. These patterns seem to add up, I instructed to be told any time she's sighted, I watch over my men who follow her.
