Silence... There was absolute silence as Izen spoke of the possibility of Gabriel being the Lord of Darkness. Even though it was only a possibility that he suggested, but even then it couldn't be ignored!
The one saying that was the Dean of the Academy of Elements after all. He was an existence that could stand shoulder to shoulder with the Lord of Light!
Unfortunately that's also why Gabriel hated him. Even after so many precautions, the man was still able to sense something. A subtle killing intent flashed in Gabriel's eyes which he hid instantly.
He couldn't show his hands. If he did, it would've confirmed Izen's suspicions.
The Head Priests looked back and forth between Gabriel and Izen. Some of the Head Priests wanted to allow Izen to check Gabriel just to be safe. However there were also some who felt that allowing Izen to do as he pleased with the Holy Lord was the same as allowing him to trample on their dignity!
