A God, but not here.
Event - Death Troopers!
This Separatist Listening Post was forgotten by the Empire - who had otherwise been so careful to eliminate all traces of the Separatists, in fear of some degree of uprising - for a very good reason. It was home to an exceptionally secret biological weapons lab, which not even the likes of General Xeli would be aware of, undoubtedly, and when it had gone dark it had been working on a pathogen designed to turn those affected into mindless slaves for the Empire - or enraged beserkers against their friends, families, and comrades.
They failed spectacularly.
Instead, they created a non resilient pathogen of an entirely new type and build - not a virus, nor a parasite, nor a fungus - which killed the host, and then proceeded to take control of it, even going so far as to partially bring them back from the dead in order to rebuild the few parts of the body it needed to maintain control, such as the brain stem, the spine, and some more major joints.
How it does this, I have no idea. And the scientists behind it couldn't answer if you asked them, because they're zombies now.
Honestly, that should tell you everything you need to know.
A garrison of 80-100 Stormtroopers, plus a staff of 10 scientists and 20 lab technicians, and four engineers, fell prey to it - not counting the 'volunteers' for testing on. But not before the engineers, lab techs, and a few of the more competent storm troopers could hole up in one of the hangar bays for a month, and decide to try and destroy the station with themselves on board to ensure that the pathogen would never find its way out and into the galaxy at large.
That would be the power signature - a brilliant weapon designed by the engineers and lab technicians together, utilising every last part of explosives they had, and a significant amount more that they had to manufacture themselves. To be more specific, the power signature is the result of the manufactured explosives cells, which, in their unexploded state, act a little like slowly decaying Hyperdrive fuel.
It goes without saying that the 'survivors' did not survive long enough to actually detonate the bomb - the Death Troopers broke past their barricade at the last moment, and killed them all before they could finish the wiring in the last panel - but it is mostly complete.
If anyone were to have their ship's droid perform an explosives scan, they'd know about the bomb, too.
But for now, I'm going to settle with three or four of the Death Troopers breaking out of a ventilation duct they'd found themselves in, and tearing apart a smuggler.
He screamed as they pulled him back up towards the shaft they'd fallen through, their legs still caught in it, and their talons and teeth ripping into his flesh, and in less than the sixteen seconds it took everyone to react to it, he was very, very dead.
RIP smuggler.
