Jedi knight Odan-Urr is called upon by Jedi Master Ooroo to assist the Empress Teta in uniting the final planet of the Koros system, Kirrek. Upon arriving on Cinnagar he meets fellow Jedi Memit Nadill and informs him of the art of Jedi Battle Meditation - by using the force you can place courage into the minds of your allies and fear into your enemies. The two arrive on Kirrek where pirates have taken Teta's soldiers hostage, slaughtering many. Odan-Urr and Nadill use the force to implement this Battle Meditation and are successful, the pirates retreat in fear but not before a couple of them strike out in desperation and destroy an incoming supply ship. On board Hok and Timar Daragon are killed.
Their two children, Gav and Jori Daragon, are informed by Aarrba the Hutt about the unfortunate accident on Kirrek. The two vow to make their parents proud and set out to explore the galaxy.
Gav and Jori Daragon, aboard their "Starbreaker 12", exit the orbit of the planet Cinnagar to once again explore the galaxy and hopefully discover a new hyperspace route for travellers. But once again they have no success and worse yet they damage their ship in their latest attempt to find fortune and fame.
Landing back on Cinnagar they approach Aarrba the Hutt about getting their ship repaired for credit. This time, however, Aarrba says they cannot get their ship back until repairs are paid in full. Gav has one last attempt to turn Aarrba around on the subject by showing him that their last route was certified by the Navigators Guild and the bonuses will be coming in any day.
Ssk Kahorr, a merchant lord, is sending a drone ship to Goluud Minor through the new route Gav and Jori discovered, aware of the risk. His ship however is destroyed when it arrives at the destination and is caught in the gravitational pull of Primus Goluud, a red supergiant sun. Ssk Kahorrr is furious at this and sends his employee, Gorrm, to find out who is responsible for the approval of the Goluud Corridor route and to kill them.
As Jori wanders through a Public Plaza on Cinnagar depressed about her current situation, the Empress Teta and her guards enter the city offering hope and joy with the unification of the seven worlds. As jedi Odan-Urr makes a speech, Jori regrets not learning the powers of the force, for which her and Gav had demonstrated they were high potentials in learning to become jedi.
In Aarrba's repair shop, Gav is still questioning Aarrba in regards to the "Starbreaker 12" for which Aarrba gives the same reply "as soon as you have the money". Gav tells the Hutt that he was just informed by Shodon Ko (a worker at the Navigator's Guild) that a merchant is already using the route he and Jori discovered and that their money should be in soon. As Gav leaves he is confronted by a gang of Ssk Kahoor's who inform him that Shodon Ko is dead and that he and his sister may be next due to their no-good route through Goluud.
Word gets back to Ssk Kahoor about his henchmen locating Gav and Jori and he orders assassins to kill them. As Gav and Jori prepare to sleep in their tent for the night, they are attacked by these assassins and are about to meet their ends when suddenly Jedi Odan-Urr and Memit Nadill intervene and save the day.
Fearing for their lives, Gav and Jori decide to leave Cinnegar for good and stealing their ship they head off into the unknown hoping that this hyperspace jump will bring them some better luck.
On a planet unmarked on any Old Republic map, Korriban is a planet of Sith evil which resides on the far side of the galaxy. Here a funeral is taking place for the former dark lord, Marka Ragnos. Ludo Kressh, who hopes to be his successor, leads this procession following the traditional rituals to the strictest detail.
Meanwhile Gav and Jori Daragon pray that their current hyperspace jump will offer some hope. Going further than any recorded vessel from the republic has ever gone, the "Starbreaker 12" comes out of hyperspace in an unmapped region of the galaxy.
As the funeral procession continues, Sith lord Naga Sadow arrives late sparking off rivalry between he and Kressh. Sadow claims "it is time for a new dark lord of the sith, by rights it should be me". Sadow feels the ancient empire needs to grow, that they need to conquer new worlds and expand their tyranny. Kressh, on the other hand, wishes to keep with tradition and not risk such changes. As Jori and Gav enter the orbit of Korriban, Ludo Kressh and Naga Sadow begin a duel for the right to rule - the winner will become the dark lord of the Sith, the loser must die - but as their battle continues they are interupted by the spirit of Marka Ragnos.
Ragnos tells them of the ancient times, that their ancestors were once mighty jedi of the republic, brothers in the force until the great schism between the dark side and the light turned jedi against jedi. "Our ancestors were defeated, driven off and cast out but we turned our exile into victory, here on the far side of the galaxy.... In these unblemished worlds we found the Sith people treated us as gods! After many centuries some of us have interbred with the Sith .... while others still bear true jedi blood." Ragnos warns them that changes are coming and they must join forces to maintain the Sith Empire or all will be lost.
On Koros, in the palace of Empress Teta, jedi Odan-Urr awakes from nightmares and hurries to the throne of Teta who is currently speaking to Aarrba the Hutt regarding the treachery of Gav and Jori Daragon. After Empress Teta promises Aarrba that word will not get out that the hutt extended credit and that the Daragons will be punished, Odan-Urr tells of his dream and warns that even though the evil jedi were banished centuries ago, they are not forgotten. Teta acknowledges this and claims that they will not be unprepared.
Elsewhere, on Korriban the spirit of Ragnos has disappeared leaving Kressh and Sadow at a standstill. Their debates continue but are quickly interupted by the arrival of the "Starbreaker 12". Gav and Jori see the gold and jewels and become excited at the fortunes they could make with intergalactic trading but when they land and express their greetings they are immediately taken captive while Kressh and Sadow argue the new arrival's fates.
On the planet Ziost, central world to the Sith lords, an assembly of dark lord contenders debate what to do with the new arrivals, Gav and Jori Daragon. Ludo Kressh argues that their tale of being peaceful visitors looking to trade is false, that they are republician spies and should be executed immediately. Naga Sadow and Ancient Simus disagree with this claiming it is an opportunity to expand their empire.
Later, in the prisoner level below the fortress of Ziost, Gav and Jori Daragon are discussing their situation when Simus is presented to them and informs the two travellers that their fate has been decided by the council and they are soon to be executed. Gav and Jori comfort each other and regret past mistakes as they come to terms with death.
Meanwhile, in the holding bay where the "Starbreaker 12" is impounded, Naga Sadow's soldiers search the ship and take several weapons. Sadow overlooks this (via holographic transmission) from his private stronghold on the dark side of the moon, Khar Shian and plans his attack on Ziost. He is determined to make it look like Ziost is under attack from an outside enemy and hence unite the Sith to oppose this force.
Using the traveller's weapons, Sadow and his men break into the prisoner level and rescue Gav and Jori Daragon, killing anyone who gets in their way, including Simus. Sadow then leaves the foreign weapons at the scene with the hope that the other Sith lords will come up with the conclusions he is expecting.
Sadow accompanies his new hostages to Khar Shian and then returns back to Ziost where the council has assumed they are under attack from the Republic. Sadow is shown the foreign weapons and told of the sad demise of Simus (Sadow's mentor and friend). After a fitting compassionate scene regarding his mentor (Sadow could be up for an Academy Award here) Sadow convinces the council to go to war and elect him as the new Dark Lord. Kressh however, is furious and vows to depart the council and take his own followers with him. Sadow, not at all worried about Kressh's departure, begins to plan his attack on the Republic.
On Ziost, Naga Sadow is receiving the badge of power as he is inaugurated, the new Dark Lord of the Sith. While on Coruscant, Empress Teta arrives to inform the senate of Odan-Urr's premonition - that a great danger from the past has resurfaced, the lords of the Sith Empire. The senate, which also consists of jedi, does not give Teta's warning much creedence though. Despite this, Teta is still prepared to summon her own forces in case of an attack.
Meanwhile, across the galaxy on a moon called Khar Shian, Gav Daragon, separated from his sister, waits in a prison cell, bored and wanting desperately to go home. Sadow has been training him in the Sith ways and appears via a hologram to inform Gav that he must master the sith magic he be taught before he can see his sister and return home safely.
While Sadow sits at his throne he receives a message that Ludo Kressh is guarding the "Starbreaker 12". Sadow immediately sends an army to "flush out this weakness" in his empire while he personally travels to his decoy fortress on Khar Delba where Jori Daragon awaits in her cell worried about her brother and the point in time when they can go home. Sadow informs her that he has separated them so that in case one of his fortesses is attacked he still has one survivor. He also informs her that their ship will soon be in their hands again.
At the Impound hangar on Zoist where the "Starbreaker 12" rests, Ludo Kressh's soldiers come under attack, as they fall they recognise the insignia of Naga Sadow but as Sadow orders: there are to be no witnesses and no evidence except evidence they shall plant deliberately. Ludo Kressh, hears the alarms and discovers the news of his men. He ventures down to the hangar just as the "Starbreaker 12" blasts off. As Kressh's guards search the wreckage they come across Naga Sadow's mask leaving Kressh to believe that "maybe it wasn't an attack from the republic at all."
Kressh returns to his personal chambers, on the planet Rhelg, where he calls upon Horak-Mul and Dor Gal-Ram. He informs these two that he believes Sadow has staged both of the so-called Republic attacks and asks them to gather their forces so together they can stop Sadow once and for all.
Back on Khar Delba, Sadow once again visits Jori and gives her a holographic message from her brother. Delighted to see Gav is okay, she thanks Sadow who informs her of more good news and leads her to the "Starbreaker 12." As this is happening, Ludo Kressh's warships attack the fortress with strict instuctions - "we're not interested in Sadow's surrender", Jori yells out to Naga Sadow to take cover while he bemuses himself - "Exactly as I have planned".
As Ludo Kressh attacks Naga Sadow's fortress, Sadow urges Jori Daragon to escape in the "Starbreaker 12". She inadvertently agrees while Sadow congratulates himself that all his plans are coming into fruition
Meanwhile on the moon Khar Shian, Gav Daragon witnesses a large fleet departing from the moon's surface and attempts to find out what's going on without much luck. Elsewhere, his sister, Jori, flies the "Starbreaker 12" off the surface of Khar Delba and without too much difficulty gets past Kressh's ships and zooms into hyperspace.
After Sadow watches Jori's flight to safety, he commands his fleet from the moon Khar Shian to attack. Suddenly Kressh realises he's been tricked. Horak-Mul and Dor Gal-Ram are the first to witness Sadow's victory as they are attacked and killed by their own crew but Kressh manages to retreat.
On Khar Shian, Gav has figured out how to monitor the battle that goes on in the distance and realises his sister has escaped. On Khar Delba, Naga Sadow rallies up his armies with the news that they will soon expand their empire and that "Jori Daragon will lead us straight to the heart." As Jori continues her hyperspace jump, a small homing device beacon beeps constantly.
