2014: The Lord of the Rings Online:

The Five Rivers were the Gilrain, the Serni, the Sirith, the Celos, and the Erui. Each of the rivers was the domain of a River-Maiden, one of the Five Sisters of Lebennin. By the time of the War of the Ring, the Five Sisters were considered a myth by most of the Men of Lebennin, though it remained traditional to leave baskets of flowers as offerings to the rivers.
