Xandros' animosity toward Dragun was revealed the moment he glared at him. The killing intent he exuded at that very moment was not the typical surge one experiences when overcome with the urge to kill; it was far deeper.
Rowan could not help but wonder what Dragun had done to such a powerful dark mage.
Come to think of it, Rowan didn't truly know what Dragun had been doing during his time away from Winterseed. Although they spoke quite often, he never had the opportunity to inquire about his past.
Apparently, Dragun's unknown past must have been the reason Xandros harbored such intense hatred towards him, and that very hatred likely drove Xandros to come to the village under cover. It was no wonder, as he had been extremely close with Xandros during his acting period.
While Rowan processed this information, Xandros withdrew his killing intent and fixed his intimidating gaze back upon Rowan, awaiting his response.
