I know Dark Empire is not everybody’s favorite story, but it does have some neato stuff.
World Devastators are one of those things that I think are really appealing. The idea of giant ships leeching resources from a planet is cool, evil, and does make sense as a tool for a shattered but resurgent Empire (a Dark Empire, if you will).
Devastators also pump out Droid TIE fighters, which are aesthetically my second favorite version of TIE after Interceptors.
Devastators are very similar in concept to Star Forges, though rather than being ancient Sith weapons, they are cutting edge Imperial technology, drawing parallels to the connection with WW2 Nazi Wunderwaffe ideas, a perfect fit for the Empire.
The blocky look and the AT-AT inspired landing legs scream how heavy and implacable they are.
A great addition to the history of Star Wars ships.
"There’s no point in acting surprised about it. All the planning charts and demolition orders have been on display at your local planning department in Alpha Centauri for 50 of your Earth years, so you’ve had plenty of time to lodge any formal complaint and it’s far too late to start making a fuss about it now. …
What do you mean you’ve never been to Alpha Centauri? Oh, for heaven’s sake, mankind, it’s only four light years away, you know. I’m sorry, but if you can’t be bothered to take an interest in local affairs, that’s your own lookout.
