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.
