Green Isle originally was the home of multiple otter clans, including the Streamdogs,Shellhounds, Galedeeps, and others, all ruled over by the High Queen Rhulain. However, it was eventually taken over by feral wildcats, who riled the cat population, took control, and made most of the otters within the clans slaves. In the time of Riggu Fellis, a notable wild cat ruler, the new High Queen Rhulain, Tiara Wildlough, lead a revoulution and reclaimed the island. Notable spots include a scorched area near a cove, where the palace of the wildcats stood before burning down, the Deeplough, where once a primitive beast called the Slothong was kept before being slain, and Holt Summerdell, the summer retreat of the otters.
