roads are physical representations of   
 the lines on maps  that  tell  you where 
             you can travel.              
 those  called  roads  are  for cars. for 
 bikes they are  called paths, for trains 
          they are called rails.          
 when traveling by foot, you  can  follow 
          all of these, or none.          
    most roads are elevated, suspended    
 between  three  to   a  hundred   (rare) 
 meters above ground. the closer  you get 
 to  a  city, the more  intertwined  they 
 in  such   areas,  all   crossings   and 
 intersections are placed in tunnels,  or 
   special tower-like structures called   
 outposts, which  enfold the roads  where 
              they interact.              
 here and there  you will find symbols in 
 white, on  the asphalt. these are  meant 
 to   tell   the   drivers   about   what 
 manouvers they  allowed  to  perform  on 
     that particular stretch of road.     
 however, some  creatures paint their own 
   illicit symbols encoding territorial   
    claims, nearby resources, or other    
      unknown and mysterious things.
