How would you incorporate the legend surrounding the Headless Horseman into your world?

You can use any (or all) of the variations on the legend, just tell us what role that character would play in your world/setting, and what shape that would take. <br><br>This is a shopping list thread, so just go ahead and put your name and world name if you want to be informed when the compilation gets posted (same goes if you previously posted in one of these threads)
