We need to talk about...orcs. Where do they come from? Are they ruined elves, or something else? What is the history of Tolkien's own thoughts on the subject? Are they problematic, associated with a form of racism current in mid-20th century, or is CS Lewis' defence of Tolkien's shades of grey in his morality right? If you want to understand more about these key characters in Tolkien's world, or even put your own point of view across in (politely phrased) comments, have a listen to Julia Golding and Jacob Rennaker as they do a deep dive into the dark underworld of orcs.
