(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.
