Where are the camps to do burning blade rituals?

Sorry if this is me being dumb but I haven't played the game in a while, but me and my friends have just managed to take over the burning blade and apparently we're supposed to do rituals to get the skeletons back and get more money? I had a look at the wiki, and it says that I need to go to skeleton camps around the map, but where are they? Am I just being dumb?
