Andrew Fork is released from the Hospital. Fork attempts to assassinate HQ chief Kubersly. Reinhard decides to lead the main fleet against Geiesburg while Kircheis, helped by vice-admirals Lutz and Wahlen, will take control of the other areas. Meanwhile, in the Free Planets Alliance, a military uprising begins (April 3, 797 S.C. / 488 I.C.). In Heinessen, a military coup overthrows the High Council (April, 13): the National Salvation Military Council, led by admiral Greenhill, suspends the democratic institutions. Trüniht goes into hiding. Yang decide to fight for democracy : the 13th Fleets leaves Iserlohn (April, 20) while the 11th Fleet goes out to stop it.

The Lippstadt League plans to draw Reinhard to Geiesburg in order to defeat him in a decisive battle. As a part of this plan, admiral Staaden has to lead a fleet to Odin in order to cut Reinhard's fleet from its base. Mittermeyer is sent to intercept Staaden, whose fleet is crushed during the battle of Altener and withdraws to the Rentenberg fortress. Reinhard decides to take the fortress, but the boarding parties are repelled by the garrison, led by admiral Ovlesser. An assault led by Mittermeyer and Reuenthal succeeds, and Ovlesser is taken prisoner. Reinhard wants to execute him, but Oberstein advises to send him back to Geiesburg. Ovlesser is released, but is executed by Braunschweig who thinks he was freed because he turned against him. Fear of treason spreads among the Lippstadt League.

Schenkopp takes control of the rebel planets on behalf of the Yang fleet. The National Salvation Military Council sends commodore Bagdashu to Yang to pose as a traitor to the coup in order to kill him, but Schenkopp manages to take him away. Yang's 13th Fleet meets the 11th Fleet in the Doria star system; the 11th Fleet is destroyed because its commanders turn down Yang's proposal of surrender. After the battle, Bagdashu decides to join Yang because his victory is certain. Meanwhile, in Heinessen, a peaceful gathering against the coup is held in a stadium. When the army tries to scatter it, it turns into a riot, and thousands are killed, including Jessica Edwards.

Littenheim leaves Geiesburg with his fleet to recover the territories conquered by Kircheis. Because of its lack of discipline and overconfidence of its commanders, the Littenheim Fleet is defeated; while running away, Littenheim's spaceship opens fire on allies who are in the way. In the Garmisch fortress, Littenheim is killed by his men, enraged by such an attitude. Meanwhile, Reinhard's fleet arrives in the area of Geiesburg. The Lippstadt Fleet attacks him but is utterly beaten and barely avoids complete destruction thanks to admiral Merkatz.

And uprising takes place in Westerland, one of Braunschweig's territories. He decides to kill all the inhabitants by a nuclear strike. Reinhard hears about the plan and wants to send a fleet to stop it, but Oberstein thinks it's better to let it happen, record it and use this monstruous act as a propaganda tool against the high nobles. Reinhard is against it, but Oberstein's plan succeeds because he lied about the time of the strike. The images are nevertheless broadcasted in all the Empire: Reinhard becomes the hero of the commoners and, even in Geiesburg, many think its time to get rid of the high nobles. The Lippstadt Fleet makes a last sortie, but is defeated; baron Flegel is killed by his men when he wants to make a suicide attack, and his crew flees to Phezzan. Merkatz, too proud to surrender, decides to kill himself, but Bernhard von Schneider advises him to take refuge in Iserlohn. Braunschweig is forced to commit suicide by Ansbach, his chief retained, who promises to avenge him. September 797 S.C. / 488 I.C.: fall of the Geiesburg fortress and end of the Lippstadt League.

After Yang's victory, the National Salvation Military Council loses its supporters and only controls Heinessen, well protected by the Artemis Necklace. Yang decides to use propaganda and asks Bagdashu to publicly admit that the Empire is behind the coup. Bagdashu's speech is widely broadcasted in Heinessen. The leaders of the coup are astonished, but Lynch, who helped them, says that's the truth. Meanwhile, Yang manages to destroy the Artemis Necklace. Hopeless, the leaders of the National Salvation Military Council decide to surrender, but to destroy all evidence of the Empire's involvement. Admiral Greenill and Lynch are killed in the ensuing gunfight. Democracy is restored. Trüniht, hidden by members of the Earth Cult, comes back to power.

Kircheis arrives at Geiesburg. He has an argument with Reinhard about the handling of the Westerland events. Reinhard assumes full responsibility for Oberstein's actions. A message is sent from Odin: Lichtenlade is plotting to get rid of Reinhard. Reinhard receives some rebel commanders. Adalbert von Fahrenheit joins Reinhard's team. Ansbach comes in with Braunschweig's coffin, but takes out a weapon and aims at Reinhard...

Ansbach misses; Oberstein protects Reinhard with his body while Kircheis grabs the weapons, but is killed in the process. Reinhard is devastated by his friend's death and is unable to make any decisions for several days. His admirals go back to Odin, arrest Lichtenlade for the murder attempt on Reinhard. Reinhard finally recovers and speaks to Annerose, who decides to retire to a small cottage; Reinhard feels left alone. Meanwhile, in Phezzan, Rubinsky decides to change his strategy, since the balance of power cannot be maintained: Phezzan will support the Empire. He sends Boltik as Phezzan's ambassador to Odin and replaces him with Rupert Kesselring.

January 1, 798 S.C. / 489 I.C.: Reinhard von Lohengramm is now Premier and Commander-in-chief of the imperial military. He implements many reforms for the welfare of the people. Meanwhile, an training sortie, under Dusty Attenborough's command, turns out to be Julian Minci's first battle as a fighter pilot. The Attenborough Fleet is on the verge to be crushed, but Yang Wen-li, with the help of Admiral Merkatz, goes out of Iserlohn with the whole fleet and saves the day (January, 16).

January, 798 S.C. / 489 I.C.: Admiral von Schaft, head of the Science and Technology Division, works out a plan to take Iserlohn back. The Geiesburg fortress is to become a mobile fortress by adding warp engines: its firepower is a match to Iserlohn's, so the Imperial fleet will be able to defeat the Iserlohn Fleet. The operation will be under Admiral Kempf's command, with Admiral Müller as second-in-command. In Phezzan, Rubinsky decides to support the plan and asks Kesselring to find a way to move Yang away from Iserlohn. Some of Mittermeyer and Reuenthal's background is revealed.

In Phezzan, Rubinsky explains his plans to a bishop of the Earth Cult. He will use his contacts in the Free Planets Alliance, such as chairman Trüniht, to make the Alliance crumble from inside, paving the way for an Imperial victory. Then, Reinhard is to be murdered. Kesselring is sent to the Alliance's commissioner in Phezzan, saying the financial support can continue only if the Alliance is a stable democracy, hinting that Yang is willing to seize power. In Iserlohn, Alex Cazellnu is concerned about Yang's safety: for the time being, his skills are needed, but he fears that Trüniht wants to dispose of him in the end. In Heinessen, Trüniht, who dislikes Yang's popularity, asks the Secretary of Defence, Negreponte, to form an inquiry committee about Yang's action during the coup.

Yang is summoned to Heinessen, where the Secretary of Defence is holding an inquiry. This move shocks his staff because such a committee has no legal basis. In Phezzan, Kesselring enlists two former members of the Lippstadt League, Leopold Schumacher and Alfred von Landsberg to carry out a plan we know nothing about. March 13, 798 S.C. / 489 I.C.: the test of the warp drive of the Geiesburg fortress is a success. The fortress and its supporting fleet can now move to the Iserlohn Corridor and attack the Alliance's fortress.

On his way to Heinessen, Yang thinks about the current situation. The Alliance's disrespect for human rights, democracy and freedom on the pretense of the war is leading the nation toward its destruction; moreover, the failed invasion of the Empire and the civil war have drastically weakened the Alliance's military. In Heinessen, Yang is separated from his companions, Louis Mashengo and Frederica Greenhill. While Yang's personality and actions are questionned by the committee, Greenhill and Mashengo try to reach him, but any contact is denied. They go to Admiral Bucock for help, but are attacked by the P.K.C. (which appears to be related to the Earth Cult) and rescued by Bucock's staff. April 10, 798 S.C. / 489 I.C.: the Geiesburg Fortress enters the Iserlohn Corridor.

While the inquiry continues, Greenhill tries to find out where is Yang and discovers that the government controls the media and leaves little room for the opposition: the Free Planets Alliance is a democracy in name only. When the news of a new imperial attack reaches Heinessen, the inquiry is suspended and Yang sent back to Iserlohn. However, the journey will take at least four weeks: Yang's staff thinks about a strategy to hold on and not let the enemy know that Yang is not there.

Geiesburg and Iserlohn fire at each other, causing little damage to the fortresses. After that, Schenkopp and the Rosen Ritter repel a boarding party. Kempf then decide to use the firepower of Geiesburg and the Müller Fleet to make a breach in Iserlohn's outer wall. The operation succeeds, but the Imperial forces can't get through because Admiral Merkatz launches the Iserlohn Fleet and drive off the Müller Fleet. Meanwhile, Yang is on his way back with some reinforcement. April, 15, 798 S.C. / 489 I.C.: in spite of the numerical advantage of the Imperial fleet, the situation is deadlocked. However, Müller learns from a dying prisoner of war that Yang is not in Iserlohn.

Reinhard is displeased by Kempf's report and decides to dispatch Mittermeyer end Reuenthal Fleet; he thinks the best tacticts was to smash Geiesburg against Iserlohn and destroy both fortresses (Yang has the same idea). Imperial scout ships detect Yang's reinforcement fleet. Kempf plans to lure the Iserlohn Fleet out of the fortress by pretending to retreat, then strike and seal it in the fortress, which will allow him to attack the reinforcements. Julian Minci sees through his plan. Merkatz, leading the Iserlohn fleet, pretends to fall into the trap, thus the Imperial Fleet is attacked from behind when it engages Yang's fleet. Kempf finally decides to smash Geiesburg into Iserlohn, but the Alliance's fleet destroys the engines, and the damaged the fortress moves randomly, destroying many imperial ships, before blowing up. The Imperial Fleet falls back but, against Yang's order, some commanders decide to pursue the Imperial Fleet.

The Mittermeyer and Reuenthal Fleets meet the retreating Imperial fleet and destroy the Alliance's pursuing ships before falling back when the Iserlohn Fleet shows up. In Odin, Müller is forgiven by Reinhard. Reinhard tells Hildegard von Mariendorf that power should not be inherited, but seized. In Phezzan, Kesselring explains to Rubinsky that the Free Planets Alliance is on the verge of bankruptcy; they decide to go on with their plan. It is revealed that Kesselring is Rubinsky's illegitimate son. Back in Iserlohn, Yang shares with Julian Minci his thoughts about military strength and how it is often used against the citizen it was supposed to protect.

Admiral Kessler, chief of the Military Police, informs Reinhard that two former members of the Lippstadt League (Landsberg and Schumacher) have arrived in Odin, and may be involved in some plot. Reinhard asks Hildegard for her advice: shes thinks they are in fact sent by Phezzan and will try to abduct someone, probably the young Emperor. later, she pays a visit to Annerose von Grünewald (Reinhard's elder sister) and persuades her to let Reinhard increase the security measures. Reinhard summons Boltik, the Commissioner of Phezzan, tells him he knows everything about their plan, and asks what is Phezzan's interest: Boltik answers that Phezzan expects to control the space communications and trade in an unified Empire. Reinhard agrees to act according to Rubinsky's plan, only if Phezzan grants a free passage through the Phezzan Corridor to the Imperial Fleet.

July 6-7, 798 S.C. / 489 I.C.: Landsberg and Schumacher kidnap the young Emperor under hidden underground tunnels within the palace grounds. Admiral Molt commits suicide over his failure to guard the grounds and product the Emperor. Hildegard sees through the kidnapping and confronts Reinhard over why he allowed the kidnapping to take place. Reinhard explains he cautiously joined with Phezzan as a method of justification for the Empire to invade the Alliance.

The young Emperor passes through Phezzan into Alliance territory. The Alliance government declares that they will shelter the refugees while the nobles announce a government in exile. Merkatz is appointed as secretary of defense without his own consent. August, 20, 798 S.C. / 489 I.C.: Reinhard declares the government in exile kidnapped the young Emperor in an underhanded act of cowardice. The public within the Empire mobilizes in support of Reinhard's declaration of total war.

Julian is assigned to Phezzan by central command. Yang and his staff decide to assign Mashengo to be Julian's body guard. Yang shares with Julian his thoughts about the possibility of Phezzan allying with the Empire due to the power balance being shifted. Julian mentions the possibility of Phezzan allying with the Empire not because of realist means, but instead out of ideological or religious reasons. Julian agrees to be of use to Yang and go to Phezzan to spy on any developments. The Iserlohn staff say their goodbyes to Julian.

As Julian travels to Heinessen to accept his commission in Phezzan; he thinks about how Yang's background in history. Julian reviews the history of humanity during this long trip. The history lesson starts with the birth of the Galactic Republic in 2801 and man's continued expansion into space. The lesson then touches on space piracy, the increase in military powers, and the eventual decadence which let to the rise of the Galactic Empire. The final parts of the lesson include the creation of the Alliance up to the first military conflict between the Alliance and Empire.

Admiral Bucock informs Julian that the alliance government is trying to divide Yang from his allies as a way of preventing any future powergrab by Yang. Reinhard discusses his plans on using the Phezzan corridor with his Admirals, calling the plan Operation Ragnarok. Over 1 million ships are planned to be in the fleet. Reinhart speaks with Oberstein and discuss the use and eventually the expendability of Boltik, current Commissioner of Phezzan. Oberstein creates a secret police with Lang as the leader. September 20, 798 S.C. / 489 I.C.: 8 month old Catherine succeeds the throne of the Empire as the new Empress.

Julian arrives on Phezzan. The next evening, he attends his welcome party. Julian spreads conjecture about a possible invasion of Phezzan from the Empire. Reinhart organizes his fleet for operation Ragnarok. Admiral Bucock tries to warn the Alliance National Defense Council about a possible Phezzan corridor attack, but is ignored. November, 20, 798 S.C. / 489 I.C.: Admiral Reuenthal leading an Imperial Fleet of 36,000 ships lays siege to Iserlohn. Carrying out the first part of Operation Ragnarok.

Reuenthal plans a war of attrition against Iserlohn. Reuenthal sees the Hyperion, Yang's flagship, emerge from port and decides to rush his fleet to destroy the Hyperion. However this is a feint and the Rosen Ritter led by Schenkopp latch on to Reuenthal's flagship and engage in combat. The battle is a draw and Schenkopp eventually withdraws. Reuenthal returns to his plan of attrition by rotating his attack forces in small groups. December 9, 798 S.C. / 489 I.C.: Part two of Operation Ragnarok launches from the Empire homeworld.
