Graham would've heard some rumors about these creatures. They're called Perytons, terrifying stag-headed bird monsters before. They hunted people near the mountains, as well as along the coast, often diving down from on high to gore people upon their horns, and then tearing them apart with it's claws. They have very keen senses and chances are it [i]will[/i] find Yin despite her best efforts, and despite it's size it's [i]extremely[/i] agile, fully capable of diving into a crowd of soldiers, picking them off one-by-one without giving them a chance to strike back at it. It takes full advantage of it's flying ability to stay out of range of melee attacks, and even if you're a skilled archer conventional weapons don't seem to affect it as much as one would hope.
