Korriban Crystal

Korriban Crystals are the name given to special alchemically treated crystals developed by Uvon Okdoro of the Cult of Shadow to siphon the Dark Side essence from the remains of the planet Korriban after it was destroyed by the third Death Star. The appearance of the cystal varies, but the one uniform trait that can be attributed to them is their reddish-glow. It is unknown exactly how many of the crystals have been created, but it is thought to be considerable as the cult wasted no time in taking advantage of Korriban's destruction.

Once the power is siphoned, it remains trapped forever in the crystal and can be used for a multitude of purposes - usually to power Dark Side devices such as Sith amulets. The crystals are known to have been used in Sivter's private meditation chambers, where they aid him in his visions. They've also been integrated into the cult's Eradicator-class Droids, which allow the droids to call upon and use the Force. It is even rumored that Sivter uses a small crystal to power his lightsaber.
