Ravaged by the Great War, the Sith Order allows Force-sensitive slaves into its ranks. Most slaves are too weak to complete the trials. But one slave displays incredible cunning and a fearsome talent for the dark side. Begrudgingly instructed by Overseer Harkun, the slave acolyte conquers the trials, dominates a Dashade assassin named Khem Val into servitude, and overwhelms the other students, including a Sith pureblood groomed for success. Despite Overseer Harkun’s attempts to sabotage the slave and preserve the pure Sith legacy, the acolyte triumphs to become a Sith inquisitor. The enigmatic Sith Lord Zash embraces the inquisitor as her apprentice, beginning the former slave’s ascension to power.
Chapter One: Scion of Kallig
The Sith inquisitor answers to Lord Zash, an eerily pleasant Sith Master. At Zash’s bidding, the inquisitor sabotages and ultimately destroys the cyborg Darth Skotia, thus paving the way for Zash to take his place and become a Darth. Zash graces he apprentice with power and sets the Sith inquisitor on a new mission: the recovery of artifacts once belonging to the ancient Sith Tulak Hord. With these artifacts, Darth Zash will complete a ritual to bestow considerable power on Zash and her apprentice.
The Sith inquisitor scours the galaxy for Tulak Hord’s artifacts. Early in the hunt, the inquisitor awakens the Force spirit of Aloysius Kallig, an ancient apparition who died millennia ago. Kallig reaches out to the inquisitor and reveals that they share a bloodline – the inquisitor is the heir to Kallig’s ruined legacy. Kallig pledges to help the Sith inquisitor restore honor to their bloodline. Guided by this new ghostly ally, the inquisitor seeks out the remaining artifacts for Darth Zash and builds a personal power base along the way.
With the Dashade assassin Khem Val in tow, the inquisitor returns to Darth Zash and interrupts her in the middle of a dark ritual. Zash welcomes her apprentice and reveals her terrible secret: Zash’s youthful appearance is only an illusion – in fact, the Sith Lord is ancient, and her body disfigured by the dark side. Zash now plots to achieve eternal youth by possessing the inquisitor as her next body. But when the inquisitor attacks Darth Zash, the Dashade Khem Val sabotages the ritual – inadvertently trapping Zash’s consciousness inside his body. Despite her best laid plans, Darth Zash is bound within Khem Val and forced to serve the very apprentice she sought to dominate.
Chapter Two: Spirits of the Past
With Darth Zash subdued, the Sith inquisitor inherits her power base and becomes a Sith Lord. But the inquisitor nearly loses everything after being caught in a trap devised by Darth Thanaton, a supremely powerful Sith and harsh traditionalist who bristles at the idea of a former slave rising to sudden influence. To combat Thanaton’s insurmountable strength, the inquisitor learns the ritual of Force-walking and gains power by consuming the energy of Darth Andru, a seething Force spirit locked away on Dromund Kaas. Fueled by the ghost’s power, the inquisitor confronts Thanaton – only to be nearly eradicated by the superior Sith’s dark sorcery.
The inquisitor plots revenge. Kallig, the inquisitor’s ghostly ancestor, advises his heir to seek out more spirits in preparation for a second duel against Darth Thanaton. The inquisitor explores the far reaches of the galaxy to bind the power of more Sith apparitions. Along the way, the inquisitor amasses more allies and even takes on an apprentice, the former Jedi Padawan Ashara Zavros. Seething with rage, strength, and passions of fallen Sith, the inquisitor once again challenges Darth Thanaton. Though Thanaton struggles against the inquisitor’s increased might, a sudden explosion of Force energy ends the battle and casts the inquisitor into darkness.
Chapter Three: Thanaton’s Last Stand
The Sith inquisitor recovers from the violent explosion. Darth Thanaton escapes in the blast while the inquisitor’s allies save their wounded Master from the rubble. The explosion that nearly destroyed them all was sparked by the uncontainable power of the Force spirits bound within the inquisitor. Now the inquisitor suffers from a crippling sickness that will prove devastating – if Thanaton doesn’t land the killing blow first.
The inquisitor explores the far reaches of the galaxy in search of a cure. Meanwhile, news arrives that Darth Thanaton has ascended to the Dark Council and now wields sufficient power to wipe the inquisitor from the galaxy. The inquisitor ultimately cures the sickness to subdue the once-overwhelming Force spirits and wield them as a weapon against Thanaton.
Darth Thanaton declares an ancient Sith rite known as a “Kaggath” to challenge his rival to a duel. Wielding the combined power of the Sith spirits, the inquisitor confronts Darth Thanaton on Corellia, defeats his allies in battle, and forces Thanaton to flee for safety. It is in the Dark Council chambers on Korriban that the Sith inquisitor finally corners Thanaton and utterly destroys the once supreme Sith wil the Dark Council bears witness. At their behest, the inquisitor takes Thanaton’s seat, becomes a Darth, and joins the most powerful Sith in the Empire to rule as a member of the Dark Council.
