    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.
