Kyber Crystal Powder

Weaponized kyber crystals, created using dark kyber crystals that have been ground to a powder by a ill-meaning worker It would be far less potent if ground by someone who doesn't want to make a weapon, but probably still bad to breathe or touch, would definitely burst into flame on contact.

Broken glass(?) vials have been found in many ruins around skeletons.

The existence of some kind of weapons is universally suspected, but not known. Has someone figured it out yet? If so, could be ISB agents or local hutt gang.
