Here's a little more information about the ancient Sith artifacts mentioned in the story, Angel of the 501st.

Nearly 4,000 years before the Battle of Yavin, the fallen Jedi Exar Kun took on the mantle of Dark Lord of the Sith, hoping to restore the glory of the Dark Side and forge a galactic empire of his own.

During his early efforts to steal forbidden Sith artifacts hidden away in the Jedi Library on Ossus, Exar Kun kidnapped the beautiful Jedi Healer Nariah Odine, whom he had known years before when he was a young Padawan, bringing her to his secret base on Yavin IV.

After a short, unsuccessful lightsaber duel with Exar Kun, Nariah turned what was left of her weapon into an instrument known as the metaharp, having read an account in the Ossus Library of another Jedi who had renounced violence...even in defense...and used music as a healing and meditation tool to "combat" darkness and despair.

Using her own musical talents and healing gifts, Nariah tried to sooth Kun's anger to bring him back into the light. But the Dark Lord of the Sith had delved too far into the black arts, and took a twisted delight in tormenting and abusing his healer prize.

Betrayed by his one-time apprentice, the fallen Jedi Ulic Qel-Droma, the combined forces of the Jedi and Old Republic armies were on their way to attack Yavin IV and destroy Exar Kun.

Using forbidden Sith magic, Exar Kun sucked the soul out of Nariah and enclosed her trapped spirit in a globe hidden in a secret chamber within his temple fortress.

Nariah's body, which had given Kun such pleasure, was then perfectly preserved in a glass-covered casket upon which her metaharp was placed and also hidden away in the temple.

Knowing his time was nearly up, Exar Kun assembled and drew the life force out of his worshippers, the Massasi natives of Yavin IV, to entrap and hide his own dark spirit within the walls of the temple, hoping one day to resurrect both himself and his concubine Nariah.

Sometime after the Battle of Yavin, Imperial investigators, searching for information left behind by the fleeing Rebels, uncovered Nariah's glass casket, but not the soul globe. The find of the perfectly preserved young woman's body was displayed on Coruscant at the Galactic Museum in the Sith Hall. The exhibit was an instant sensation with the public.

Overly romantic and fanciful stories, plus an grand opera, were written about the mysterious beauty Nariah Odine, the bound concubine of the Sith Lord Exar Kun, whom many believed could not stand to see her beauty fade with time.

A year after the discovery of the glass coffin, the Force-sensitive Agent Arik Ganner, an Imperial Intelligence operative who had been trained as a Sith artifact hunter, came across Nariah's soul globe in the hands of an antique collector. The globe's owner claimed the unusual "singing" object had been found by an alien researcher who was documenting Yavin IV's architecture within the abandoned Sith temples of the moon centuries before.

After murdering the collector, Ganner brought the stolen globe before his master, the Emperor Palpatine. Palpatine placed the captive essence within a specially built sarcophagus that housed the physical remains of Nariah.

Kept within a private Sith museum hidden deep in the bowels of the Imperial Palace, the Emperor takes a dark delight in viewing the ancient healer's preserved body, while listening to her pleas for deliverance from the soul globe.

When the Sith Adept Arik Ganner asked Lady Meena Valorian if she knew about the history of her metaharp on pages 68 and 69 of Part I of Angel of the 501st, he was referring to the story of Nariah and Exar Kun.

Arik Ganner is a true Sith romantic...he, too, is enthralled by the legend of the beautiful Jedi Healer Nariah who became the ancient Sith Lord Exar Kun's slave...and hopes to do the same by making Lady Meena his own.
