   Yes. Exactly.   
      
   To do all that you need energy.   
      
   You have to position exactly your moons at the right places.   
      
   Then, they have to shepherd the new material into the rings.   
      
   There is a dark material circulating across the whole   
   system, in the surface of the first satellite the machine   
   passed by, and in the rings too. Titan has an extended   
   atmosphere that could be the source of the injected material.   
      
   This material is injected into the rings by the moons   
      
   How come that they are at the right place?   
      
   The deeper you look, the deeper the explanations look strange.   
      
   Saturn. We know nothing yet...

   I know of another proces that can turn chaos into order.   
      
   Those patterns in the rings... Fascinating isn't it?   
      
   They look like bar-codes.
