Tarkir stopped for a moment he heard muffled footsteps around the corner, he could make out 3 different footfalls but couldn't be completely sure. The footfalls were light and tense so it couldn't be a student going to class, they were waiting for something. He was agile and strong for a human but if these were vampires waiting he would have to flee and flee fast. His heart beat raised and his hairs stood on end, he had made his decision moving to the outer side of the corner revealing himself to the the 3 students. Thankfully they were day students, though he couldn't under estimate them, his gaze met the eye of the leader. He smiled showing his teeth.
