Westchannel is the main waterway of Westcrown. It splits sharply from the River Adivian directly after the split of the Dhaenflow. Garbage rarely flowed into Westchannel, and people said that Westchannel is blessed by Aroden. The truth is that a century after Aroden's passing, more and more wood, ship wrack, and other flotsam drifts into the Westchannel and the island's canals.1
