The kings
Kayden had no reason to be friendly with these people. He and Atlas were destined to fight to the death someday in the not-so-distant future. Moreover, Kayden had no interest in forming ties with the powers of this universe or being dragged into their chaos.
"You'll regret this. Our universe doesn't have the strength to withstand the invaders. We'll be consumed..." Ryan started, but Kayden interrupted him again, this time making his intentions much clearer.
"You have three seconds to get out of my sight, or we'll fight to the death."
This time, his words carried all the killing intent possible, and both men had no doubt that Kayden would attack in three seconds. In the blink of an eye, they disappeared from Kayden's presence. Their agreement with Thoth prevented them from fighting Kayden, or things would have turned out... very differently.
