Many have wondered....why did Palpatine have so many superweapons built?Why not spend money on more conventional ships,like Star Destroyers?Certainly all those weapons weren't needed to destroy the will of one galaxy...he was doing just fine without them. That is true.Palpatine didn't need them to conquer the SW Galaxy.Rather he needed them to conquer galaxies. I've been reading through the DE Sourcebook recently,and I've discovered all sorts of gems of info in it. Palpatine's only desire was ultimate power.Supreme power.He only wished to make a mark on the galaxy.Nothing more.He had no desire to bring order to the galaxy.In fact ,he had set up the Empire so that if he ever failed,the Empire would would collapse into civil war and take the galaxy with it.(luckily the bulk of the Empire was destroyed at Byss... there was nothing left tto wreck havoc,there was very little to fight over,and to very little to fight with) Palpatine's ultimate goal was to spread his dark will over the universe.Hey...he was eternal.He would have the time to do it.He planned to conquer other galaxies. Let's take the World Devastators.These weapons were supposed to be the lead ships of a galactic invasion Force.They';re basically mobile bases/factories/shipyards/colonies. A world devastator stripmines a planet.It sucks up everything in it's path and uses whatever's useful.A devastator is like a living thing,in that it grows.It uses the raw materials to make itself more powerful.It can get bigger and more powerful. Imagine a fleet of devastators in another galaxy.They wouldn't need to go back to the Empire proper for supplies and reinforcements.Nope.They have everything they need.They could become entire colonies,mamufacture Imperial Class Stardesroyers,fighters, etc etc.All the devastators would need for an escort at first,would be an Eclipse or Sovereign Class Super Star Destroyer.Ships armed with mini superlasers. The only problem I see with Palpatines plan is maintaining control over the guy you put in charge of watching you galaxy. But you could always have the devastaors program codes into all Imperial machinery,codes that would allow you to destroy or control any single bit of Imperial technology,if someone tries to use it against you. Then again knowing Palpatine,he probaly had some Sith trick up his sleave.
