Place the totems starting at -7, -632, -718 (there will be a white sparkle when you can place it) and then going clockwise around the ritual area.
NOTE If someone else has done this quest recently, there might be a delay before you can place a totem. Wait about 5 minutes max then the area will sparkle and you can place one.
