   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.
