Shadowtrooper

"The Shadowtroopers will serve the Sith well. The Jedi cannot kill what they cannot see."

- Darth Sadis

Shadowtroopers were Stormtrooper-Dark Jedi hybrid soldiers created by the Dark Jedi Desann and Imperial Admiral Galak Fyyar on behalf of Lord Hethrir's Empire Reborn. Similar to the Reborn soldiers, Desann used the Valley of the Jedi to imbue Stormtroopers with Force powers.

Equipment
The resulting Shadowtroopers were armed with lightsabers powered by synthetic Sith crystals and wore fitted Shadow armor made with cortosis. An Artusian crystal was embedded in the armor's chest plate to enhance the power granted from the valley.

Shadow armor also had limited optical stealth capabilities, although a translucent blueish silhouette was visible when the trooper moved. Their artificial mastery of the Force enabled them to use Force Grip and Force Lightning. Unlike the Reborn warriors, Shadowtroopers would not taunt their enemies, rather they would remain quiet and concentrate on physical combat, much like the Sith Lord Darth Maul.

Empire Reborn
The project behind the Shadowtroopers was based at the abandoned Imperial listening outpost on Kejim and Fyyar's flagship, Doomgiver. Desann had experimented with imbuing Empire youths who had little potential in the Force with dark side powers.

Shadowtroopers met their masters' expectations, to the extent that some Stormtroopers feared that they would soon be replaced. Shadowtroopers were first deployed in the Cairn Installation against Kyle Katarn. Several others were stationed on Doomgiver to protect the ship.

The majority of Shadowtroopers were dispatched to Yavin 4 with Desann for the assault on Luke Skywalker's Jedi Praxeum. With the aid of Kyle Katarn, all of the Shadowtroopers dispatched were either killed or taken into custody, and Desann was slain in the battle.

After the death of Fyyar and the destruction of Doomgiver, the project was halted.

Sith Brotherhood
The Sith Lord Darth Sadis had long ago heard of the Shadowtrooper project and been intrigued. After settling on Tarix he took all the knowledge of the project that his former master, Darth Kren, had and stored it away in his archives. After joining the Sith Brotherhood and training the Morgukai Shadow Army for Darth Invisus he realized he would need an army of his own should he ever wish to usurp Invisus and take the title of Dark Lord for himself. Though he all ready had hellish monsters called Blood Wraiths at his disposal, he decided to go ahead with the Shadowtrooper project anyway. He imbued Dark Side energies into individuals using Artusian crystals. He wiped their minds clean of their former lives and made their psyches more malleable. Now they serve the Lord of Pain in all his endeavors.
