Based on the current position on the mountain path, Valerion had deduced that the little girl and that powerfully old soul had reached the 'leavings' of Valerions earlier meal.
He chuckled slightly half expecting the little girl to throw up, but he heard nothing, and that was slightly more troubling. 
They knew he was there...

Now that was slightly more impressive, it only took them to this point to discover that they were being followed. But how? Life detect didn't work on him, the blizzard prevented any real sight...

Then it hit him. The man was a vampire, it was the only explanation, the age mixed with his power and the ability to discover him, it also made sense why he traveled up here at night. Could the girl be his thrall? What would a vampire want with the graybeards?
Too many questions, and the only way to get answers was to reveal himself. Keeping a tight grip on the hilt of his blade he continued walking towards them a small smile appearing on his face as he got his first view of the 2 people. The girl was cowering behind the Vampire, which answered the question that she wasn't a thrall. 
Both of them had their hands around their hips, so they obviously thought him to be hostile, or they were unsure. 
Either way Valerion got close enough for both vision and sound to be clear; approximately 5 long strides from them.
"Greetings fellow pilgrims." [i]The ruse was important[/i]
Valerion proceeded to lean a bit closer "Is that a body behind you?!" if Valerions ruse failed it mattered little to him, he just liked to entertain himself.
Something he could do very well.
