Yulio doesn't know all this.
He doesn't know about Raishti's last thoughts, nor his reasoning behind betraying his own kingdom. All he knows is....
There is a grievance in heart left that will never be satisfied now.
"Raishti... cannot be dead. No..." His beady wolf eyes skirted restlessly from the thought. "How dare he be dead without me killing him? I.... I will not allow it!"
He banged his head again and again on the cave wall. "HE CANNOT! HE CANNOT BE DEAD! NO! NO! NO!"
Now he knew what his character, Rogue, had felt on a very personal level. Azul is dead, long long, ago... and there's nothing that can fill the hole that he left after he betrayed him.
Thunders boomed outside, trees fell. There's a threat of a forest fire. But even that would be a mere small spark compared to the blazing unresolved wrath of a man-hound.
"Oh my." Vladstin said without any hint of surprise.
Meanwhile, the two humans are still on edge.
