The Leith river. Central Edinburgh.
The water of Leith was an ever-flowing river network that ran from north to south of Edinburgh. The main river along with its network of tributaries separated the kingdom of Edinburgh's lands into various parts to create the four duchies and the central region.
The central region of Edinburgh was under the direct control of the current king. This region was very rich in all forms of ranking resources thanks to the Water of Leith. The main river looked as vast as a sea if one stood at its banks from either side.
Various ships were selling in either direction of the river's flow. They all maintained a safe distance from each other, traveling at a constant speed using various elemental arrays.
Some ships would disappear from the main river by taking one of the many tributaries to the river Leith while some would get added up for the same reason. Traveling over the Water of Leith was one of the primary ways to travel in central Edinburgh after all.
