Mankind looked much like man of the present, however, they were much furrier. It would be easy to say that they were apes. By all accounts they showed a lot of the same physiology. But unlike apes, they had a higher perception of the Vibration.
The drakonians did not understand. Though centuries before they were able to vibrate with the Most High, it was a perception long lost to their kind. So as they hunted and captured as many humans as they could, it concerned them when they heard their mutters, hands clasped with intertwining fingers, eyes squeezed tight, and chins anchored to their chests.
They shivered, the humans, and what the drakonians mistook for fear, was really powerful, spiritual experience.
