(demonic)  (alchemical construct)  
        (flower)       (memetic)        
   travelers   from   a   parallel    
   world  far beyond  ours...  
  an  initial seed  places a   
  forge.  then starts the  melting,   
   the  gathering  of  materials (the   
  secret ingredient in  liquid glass  
  is blood, and in any  case,  
   a human host is needed for  
     interdimensional    travel).     
  after the entire plane is harvested,  
  comes the blooming phase where the  
   catboys  spread their eggs  
  to  whichever other worlds   
   have   drifted  close,  and  the   
     cycle   continues,   elsewhere.
