The rise of evil in Isengard threatens the country and prompts it to rise again. The country that stands alone against the evil of Sauron and Mordor. Stewards who await the return of the line of kings rule it. It is west of Mordor and south of Gondor. A beautiful enchanted forest through which the company passed before they were split.
Most men fear it because of baseless legends.
A horse Gandalf borrowed from king Theoden. It became a point of contention when Gandalf became the only rider it would accept. Eventually, Theoden gives it as a gift to Gandalf. The seat of Theoden. The forest of Treebeard where the ents dwell.
