Traveling through the realm of shadows, Cain stared into the dark ether with slightly absent eyes...
He had first senses it after he had had his battle with Balangol.
He hadn't noticed it much previously, but with the absence of his magic, it was as though this repressed sixth sense of his had chosen to rear its head.
Apparently, he had developed a nose for sensing Divinity.
Azazel had refused to give him the details of what had happened when he lost consciousness during the battle, but for whatever reason, he had come out victorious against the ancient god. It was unbelievable, but it had happened.
'Could that be the reason? Do I perhaps suddenly have a hidden skill that lets me sense divinity?'
That was the only way that could happen.
But according to what he knew and general knowledge, only the Celestials could sense, or pretty much do anything with Divinity.
