Greenrun

The Greenrun was the northern and eastern boundary for the River Kingdoms, and flows southbound marking the border between the River Kingdoms and the Kingdoms of Men. Like the Bluerun, it is easily navigable and reliably floods on a yearly basis to the benefit of many of the agrarian peasants living on the banks. It meets the Bluerun at Ner where it combines into the Redrun.

Ecology
The ecology of the Greenrun, much like its sister river the Bluerun, was a bountiful river of fish and animals as well as plants that grow on the banks. However, owing to its name, it is often covered with lilies and other water plants. Many of the tributaries that lead into the Hanglands are unexplored.

History
The history of the Greenrun is long, owing to it being a boundary between two great nations. It formed the first line of defense in the River War, and has a long past being the main traveling method between Ornn and Ner. Regardless, it is kept in pristine shape by the locals, who see it as their duty to guard it to the last as a vestibule of nature.
