The Ardeth flows down out of the mountains, past the small mining community at Hillsend, through the town of Grunal and out into the Eastern Ocean. It is a short and fast-flowing river along most of its length. During the summer it's used as a method to ship coal down to the town from the mines. During the winter months, the river becomes very fast at times and it's generally not considered safe to use it to travel. A rutted road follows the river, linking Hillsend and Grunal. This is the main form of transport when the river is considered too dangerous to use.
