The River Lynsk marks the boundary between Kislev and the Northern Wastes. It is navigable by river boats as far as Praag, although it is a brave captain who would risk his vessel on such a journey, when it is open to assault from the Chaos hordes that prowl the northern banks. During the months of winter, the river is often frozen for miles at a stretch and the citizens of Praag must look to their storehouses to survive.
