Far in the north there is a city untouched by the Wolf Riders. But it has its own battles to fight, its own history to unravel. Alagur only knows it as the North City. Marrida has never heard of it. Centuries ago, it was a magnificent city, rich in history and wealth. It was the bastion of power for the Callers. But something happened that the Keepers cannot even see in their visions. The city is not just closed physically, but in the visions as well. It is rumoured to be where the corruption of the Wolf Riders started. How or why. That is a mystery.
