Servant to Dragons
As soon as the assassin had vanished, he quickly swapped out his robes and gathered up all of his gear, sneaking out and still wearing the guard's helmet to keep himself disguised. He was able to arrive on the mountain pass just shortly after the girl since he had known the path while she was relying on a map. Up ahead he saw a rider hurrying down the side of the hill, trying to catch his attention, having noticed his guard's helmet.
"Guard! An assassin, she got into Dawnguard! She's wiped out the entire outer courtyard! I'm the only one who managed to escape! I came to get reinforcements!"
Apparently the girl had done well.
"You're the only one that escaped you say?" Drexyl asked, an icy coldness to his voice which must have been detected by the vampire hunter whose face appeared even more frightened as he nodded slowly.
"That's too bad." A bolt of lightning pierced the rider's forehead, causing him to collapse on the ground as Drexyl raced on towards Dawnguard, arriving at a bloody graveyard. He dismounted and began slowly making his way towards the entrance to the fortress, though not entering just yet. He would simply wait here for a moment to see if any more guards made their escape and once he was sure the area was clear he would follow.
