Vance's sense of smell and speed were very commendable. In only less than five minutes, Vance was already able to catch up with Eldridge and his companion. Melva had to hang on for dear life while she was on his wolf's back because of how incredibly fast he travelled to chase after Eldridge. She was almost thrown into the air a few times before they arrived to where they could see Eldridge cornering a creature that looked like a winged lion but with the head of an eagle. That must be one of those supernatural creatures.
They had come to a stop rather far away from where Eldridge was fighting the creature, because they could not see his companion anywhere near him. It was odd that the werewolf would leave the Duke when he was fighting off a creature that powerful. Melva could see how Eldridge was struggling to subdue the creature, and yet his werewolf companion was not there.
