Davroar
He knows that Elk are big and fast when they run, and the only thing that comes to mind is to take flight.
"I'll see what I can do...", replying to Jaliera as he starts running and then quickly wild shapes into a giant eagle, climbing at about 30 degrees up as he does not want to waste too much time gaining altitude as opposed to closing the distance.
While the others decide whether or not these elk riders are hostile, Davroar's plan is not to attack but merely to get their attention. As he gets closer he will let out a screech, and hopes no arrows come at him as he does a fly-by.
