When Sargeras saw Roy, Roy also saw Sargeras.
At their level, the distance of vision was no longer a problem. On this planet, Sargeras and Roy had the strongest presences. No matter how far away they were, they could sense each other.
Roy was observing Sargeras's appearance. Of course, he knew that Sargeras was still a world-soul titan, so he was very curious about his appearance before his fall. Perhaps he had seen too much of Sargeras's demon body burning with raging flames. Now that he saw Sargeras's original appearance, he actually felt that this guy was… quite handsome.
