By the power of the Three Rings, they exist as a testament to a time that was. But not only the Elves remember. As Sauron gathers his strength to bring war to Middle-earth once again, he plans a devious vengeance against those who humbled him long ago. Realms of the Three Rings™ is a supplement for The One Ring™, the official tabletop roleplaying game based on the works of J.R.R. Tolkien.
