Duncan felt as if he was immersed in a raging river.
As he concentrated on unraveling the mystery present in the blood that was held in his hands, he could feel something far grander from it. Now that he had let go of his apprehension regarding the blood, he could feel it more intuitively.
Thus a picture emerged in his mind.
In that picture, he was immersed in a raging river. The flow of the river was ferocious enough to destabilize him. He could feel its power intuitively. The river raged all around as he tried to stay afloat in it.
Furthermore, he could hear the various roars in his ears. There was a different feeling related to each and every roar he heard. He felt as if these roars were issued by different people. It was as if he was hearing people roar majestically across time and space.
