Redhawk Caldera What exactly are we dealing with here?

"Oy, YOU!" Dwin yelled at the complete stranger that was standing on the banks of the lake and calling out to someone, who was not there. She had been on her way home from the patrol on the borders and had not caught scent of any wolf that did not belong here. So - in hopes for a square meal and good nap, she had walked the usual path to the rendevouz's site, when she noticed the apparition. 

When she had come closer, she realized that this guy did not possess either a scent or any other defining qualities, save for the looks and ability to emit sounds. It did not register right away that this might not be her usual trespasser, but for the time being she was angry for having to miss out on all of the pleasant, boring things, in order to deal with this fellow. "Who are you and what do you want here?"
