Once Draven disappeared from the mountain, Aureus flew towards palace with Erlos. After facing Draven's strong divine power which destroyed the peak of that huge mountain and using his own powers to protect Erlos and himself from it's effect by creating a shield of his divine power, Aureus was slower than usual to fly from that far away mountain and to arrive the palace.
Though Draven's powers were not meant to attack them and he just had to protect them from it's destructive effects, Aureus could not help but wonder what would happen if the King of Agartha ever used that power to fight with someone. The result would sure be the defeat or death of his opponent.
When they reached the palace, all they could see from the sky was whatever was going in the garden part of the palace.
They saw everyone was using their powers to break that dome shaped barrier. He could not believe his eyes for what he was seeing.
