Comparing 2008 to 2009, we've seen catastrophic declines in castles, glowy magic and swords. Unicorns have seemingly disappeared, and even formerly sizable populations of elves, wolves and horses are in sharp decline.
Dragons, obviously made from sterner stuff, remain unscathed.
Context? Fantasy novel covers. This news courtesy of Orbit Books (via Making Light). Their handy comparison chart is reproduced to the right, but really: go read the original article. Sample quote: "The number of dragons on covers held steady this year. The dragon population seems to be in perfect balance – but we can’t tell if that’s because new dragons are being born to replace old ones, or if last year’s dragons are just really healthy."
