Forbes is well-known for publishing annual lists of the world’s wealthiest individuals. But the publication also produces The Forbes Fictional 15, a list of the wealthiest fictional characters. This year, Smaug, the dragon in J.R.R. Tolkien’s The Hobbit, ranks number seven with an estimated worth of $8.6 billion. How Forbes go to that number is a fascinating read, and includes a reference to Dungeons & Dragons for data on ancient red dragons.
