I made this plugin for Tekkub's TourGuide for the 2011 mid summer festival. This plug-in only shows the way to the bonfires in a fairly effective route.
All Credit goes to Tekkub for Putting together TourGuide as that is the framework.
Any bugs you find feel free to message me here and I will get them fixed asap.
