Hyper-point destablizer

"The world is almost uninhabitable, my lord. The loss of the hyper-point destabilizer and its delivery vehicle has caused a thermal shift in the planet's atmosphere and tectonic instabilities that may yet tear Kromus apart. We are continuing to monitor the world as you instructed, but it is increasingly difficult to remain in orbit."

- A report delivered to Darth Sidious following the apparent destruction of the hyper-point destabilizer and the Shadowblade in the Kro'eval system

A hyper-point destabalizer was a type of weapon. During the Clone Wars, the Shadowblade, a Separatist cruiser and superweapon, was armed with a hyper-point destabilizer. Around 20 BBY, the Shadowblade and its hyper-point destabilizer were seemingly destroyed following an attack by the Galactic Republic on Separatist forces in the Kro'eval system, where the Shadowblade was under construction. However, the warship secretly survived the battle and later reappeared in the Cularin system in 19 BBY, where it was drawn into a temporal rift by Jedi Master Darrus Jeht and never seen again.

Behind the scenes
The hyper-point destabilizer was referenced in the 2005 short story Dark Soul by August and Cynthia Hahn. The short story provided no detail on the nature of the hyper-point destabilizer other than noting it as the armament of the Shadowblade. While the story described the Shadowblade as a superweapon, it did not clarify whether it was the vessel's hyper-point destabilizer weapons specifically that resulted in the warship being classified as a superweapon.
