Elrond is a key figure in Tolkien’s world. The half-elven advisor may be immortal, but he’s related to just about everyone. ‘The Rings of Power’ actor Robert Aramayo said of his character Elrond: ‘When I read about him, I’m always interested in how Tolkien talks about it [how Elrond is] counted among the immortals, which is an interesting thing. Counted doesn’t necessarily mean he’s one.”
Sure, biologically Elrond is immortal. But he is related to mortal humans, immortal elves, and even the angelic Maiar (think Gandalf and Saruman, but not in their ancient wizard forms). Elrond’s crucial role as the crossroads of many of Middle-earth’s races, combined with his eternal nature, has kept him in the limelight for millennia.
In “The Rings of Power” he is a scrappy young politician. As we see him in The Hobbit movies, he is the leader of Rivendell and a member of the White Council. He continues that role in The Lord of the Rings and also helps point characters like Frodo and Aragorn in the right direction. He leaves Middle-earth at the end of this story for a quiet retirement in the blessed realms of the west, but there’s no denying that he more than deserves it at this point.
