the basement       
                      
                                         
                                          
  the basement is a man-made subterranean 
   environment where you could find such  
   things as the furnace, the labyrinth,  
            reptiles or graves.           
                                          
  a small or rural basement is a cellar.  
                                          
                                   
                                          
 often created in good faith, a basement  
   is nevertheless a way to bring a cave  
   into your building, and cave things    
  with it. i've found that it's easier to 
   think of all caves as the same large   
   structure, it's just that all parts    
    might not be physically connected.    
     that's what you're inviting in.      
                                          
                                        
              usages              
                                        
                                          
  the purpose of a basement is often to   
   hide unsightly appliances, engines,    
  infrastructure (pipes and wells)... or  
 to hide the true weight (purpose?) of a  
                building.                 
                                          
  to draw from the earth around it, push  
         above ground, laundered.         
                                          
    a cellar is a more senseful affair,   
   less intense... made to store things   
    (food or brews, tools) in a colder    
 environment. perhaps to grow mushrooms.  
  perhaps to bury corrupt creatures (not  
                 advised)
