there is a seriously sad lack of fan content for Mercedes Lackey’s elves on the road universe.  it’s such a good urban fantasy universe with four different series that don’t really interact, but exist within the same world.  one of the four, the SERRAted edge: double edge, is set in the same world, but in a more historical setting while the other three are set in modern-ish usa (probably late 80s or early 90s).  there’s such great potential to write interactions between the series and even to write about the events that are hinted at but not fleshed out within the books.  sadly I have found a total of 17 fics on ao3 for the entire universe with no fan content on ff.net, tumblr, wattpad, or da that I can find
