Here's an interesting essay on the presence--or lack of presence-of non-white folks in D&D throughout history. It's a funny thing to be a black kid into fantasy. Most of this stuff is ripped from Tolkien, and as much as I love LOTR, there is, indeed, something disquieting about the total whiteness of the movies. I don't blame that on Jackson or Tolkien. If someone was doing a fantasy epic based on Xhosa creation myths, I wouldn't expect to see any white people.
Light pollution has taken away our ability to see the stars. Can we still save the night sky?
