William wanted the serpent to feel the walls closing in, to hear the screams of his army and know that he was the ultimate prize in this hunt. Once Vladimir fell into William's mental trap and allowed his panic to override his logic, then it would be the end for him.
William had already closed all ways of retreat for that bastard. He had accounted for every tunnel, every hidden path, and every shadow. He even sent a couple of monsters down to the portal to guard it at the underground city!
There was no way out for Vladimir, and all that remained was for him to grow frightened enough to run. When a cornered animal runs, it leaves a trail. When a coward flees, he makes mistakes.
That was why William kept walking and spreading chaos; that was why he stopped at the city's outer walls, the same reason he did for the inner walls—to instigate fear, not only in his enemies, but also in Vladimir's spirit.
