You may have read The Lord of the Rings and/or seen the movies, but do you understand what's going on with those titular pieces of jewelry? This video offers a quick explanation of the various rings in J.R.R. Tolkien's universe, especially the One Ring.

After giving his quick and dirty lowdown on the mythology of Middle-earth, YouTuber CGP Grey is once delving into Tolkien, this time explaining the rings — with a little help from Knut J Håland's artwork. And Patreon supports can nab wallpaper versions of the illustrations.
