You know.. I got a Darth Vader comic. Called "Darth Vader: and the Ninth Assassin". In the comic there was a cult of mutated warlocks that praised a stone gem at the center of their temple. Which erected this light of energy that soared straight into space and sliced several Star Destroyers in HALF. Darth Vader and a couple Imperial Guards had to go figure out how to stop it. but it took quite a few Destroyers before Vader vanquished the erratic cult. I nominate something like this instead of a saboteur.
