Tracking is an essential skill that allows one to find where certain people (if they are in your contact list) or animals went. Police type characters (one who protects a village or camp) or Mercenary type characters (ones who are hired to kill other individuals) would need this ability to find out where their quarry has gone. There is untrackable terrain, which is only the swamp and water tiles (water/deep water/river/waterfall). Flying animals are also untrackable (needs confirmation).
