Actually, “Rings of Power” is authorized by the Tolkien estate/family. But the license is limited, mostly to the appendices to LOTR. Amazon generally can’t use ideas first seen in the Silmarillion or later published books (although the estate allows some use of things implied in LOTR but not made explicit until later.
This sequence makes no sense, all right. Bribery’s ring didn’t create a shield around its wearer. It turned the electric force back on the person trying to use it. Ro-zan should have been leveled and the wall untouched.
Because putting a self-proclaimed roadkill-eating heroin addict in charge of Health and Human Services isn’t pathetic and gross?
