One of the most enduring, saddest mysteries of J.R.R. Tolkien’s The Lord of the Rings trilogy is the fate of the Entwives. During their travels together Treebeard told Merry and Pip that Ents, an ancient Middle-earth race of sentient tree people, “lost” the Ent women long ago. Tolkien never revealed what happened to the Entwives in The Lord of the Rings, but The Rings of Power, set during Middle-earth’s Second Age, long before Treebeard met those Hobbits, has shown us exactly what the world lost when they vanished. Season two’s fourth episode introduced one of the Entwives to The Lord of the Rings audiences everywhere, a beautiful and loving creature named Winterbloom.
