"Do you want me to set up surveillance over them?" 

After a few moments of sitting in the car in silence, Makary finally came up with a suggestion. 

"I don't know what means those girls have that got you two so scared… But regardless of how powerful they are, they won't necessarily know all the intricate wonders of technology, would they?"

As against as I was of the idea the moment I heard it… Now that Makary expanded on it a little, I couldn't help but get a little interested. 

Because, to a degree, he was right. 

No matter how powerful one could be, it wouldn't help them when faced with technology they either didn't expect or outright don't know about. 

Just like that powerful mage from the mercenary camp that I shot dead with a single round, even though when fighting a man on pretty much the same level later on not even several rounds proved to be enough.
