Grimbrook
The Grimbrook (Rûthhir in Sindarin) is a river that arises in the White Mountains of Rohan and flows down into the Westfold through the town of Grimslade. It passes north, running parallel with the road to Brockbridge, and is crossed in a ford by the Great East-West road. The Grimbrook then angles northwest through a few bends, before it flows into the Swiftwater coming in from the southwest as it enters the Stonedeans.
