Cavalry from the Skies
Adrian could only think that the battle with the Ziz is pointless if they could not get it down to the ground. The elders have used a lot of mana in using Void Crusher while Old Man Pann is also tired from overusing his powers as well. If the old man was actually at his peak, then he might be able to deal with the Ziz himself, but all of his tamed monsters are not able to contend with it.
The other powerhouse NPCs of Avalon are also dealing with the flying monsters that are still alive. The Ziz was the only being that is not being attacked because it was powerful and quick. Only the demons that can bend time are able to slowly catch up to it. Adrian could feel that Elder Koronn was stopping time for brief moments in order for them to glimpse at the movement of the Ziz.
"Master, we must use it." Sirius stated as the domain was still active.
"Ok." Adrian agreed as he vanished from his location but an illusion of him was still there.
