This text was written by Harutoshi Fukui prior to production as a staff document. Based on the original text, the timeline shown in the story was created by novelist Yuka Minagawa, who is in charge of literary concepts, and there are some discrepancies with the main text. This is because Dezarium lost most of their historical records due to “The Great Loss,” so the timeline in the story is the “detailed history of what they were able to restore.” The main text is what you might call the “rough truth.” In the future, as Dezarium investigates Earth’s records after their invasion in 2207, their timeline will likely be revised from time to time.
2200-2300 A.D.
• End of the Gatlantis War.
• Dessler discovers the planet Galman and goes to war with the Bolar Federation.
• Garmillas immigration plan begins. However, the Bolar Federation launches an attack, and Garmillas is destroyed along with most of its citizens by a planet destroyer missile. Iscandar is engulfed in the shock wave and collapses.
• The remaining colony planets and garrison forces are mobilized, and Garmillas President Dessler founds Galman/Garmillas. The war with the Bolar Federation intensifies, and Earth is drawn into it. The First Galactic War breaks out.
• The Galactic War continues for over two hundred years with several ceasefire periods in between. During that time, the Bolar faction splits up, and after Dessler’s death, the Galman/Garmillas faction also splits up.
• The galaxy enters a de facto age of warring states. As various interstellar nations compete for supremacy, Earth’s civilization is forced to undergo a major transformation.
2400-2700 A.D.
• In order to defend itself, Earth resumes unlimited use of AI, which had been discarded after the Gatlantis War, promoting the mechanization of some humans (the revival of the G Plan = G2 Plan). Using the remains of the Gatlantis army as resources, a large fleet is built with a universal conscription system.
• Initially, they focus on self-defense, but due to resource shortages and the need to preserve the species, they eventually switch to an offensive approach. In the Galactic Warring States Period, “active Wave-Motion Gun diplomacy” is approved to ensure the perpetual survival of Earth civilization and humanity (G3 Plan). The commander is not a human, but an AI named Dezarium.
• Thus, they absorb several interstellar nations, at one point forming a federation that could be called the Earth Empire, but at the end of the 2700s, Earth is hit by a catastrophic situation.
2800-3000 A.D.
• About 600 years earlier, in the great naval battle with Gatlantis at Saturn, the Earth fleet used a huge number of Wave-Motion Guns. The damage to space that occurred at that time finally spreads as a crack, leading to the first localized “space tear” in the history of Akerius-derived intelligent life forms.
• The solar system suffers catastrophic damage from the impact, and almost all life on Earth is wiped out. Only those who had been mechanized survive, and a seemingly impossible recovery begins after everything had been lost.
• The mainframe of the AI Dezarium that had been operating on Earth is also destroyed, and humanity loses the historical data stored there (The Great Loss). In other words, the events described up to this point are merely a compilation of fragmented restored data, and the dates are based on rough guesses.
• This incident also terrifies interstellar nations other than Earth, leading to a ban on the use of Wave Energy throughout the galaxy.
• The solar system is no longer an environment in which life can survive, and the Earthlings, who have lost their imperial hegemony, search for a way to survive by bio-mechanizing themselves. Their brains and spines are extracted from bodies that are generated by random combinations of preserved genes, and transplanted into artificial biological bodies. They try to maintain their “humanness” by switching between multiple bodies until they reach adulthood, recreating their sense of growth. Their minds are connected to the reconstructed AI Dezarium, and they begin to call themselves Homo Dezarium, evolved from Homo Sapiens.
• Meanwhile, they also seek a way to repair the rift in space that appeared at Saturn. It is only by chance that they are able to maintain stability. If it were to tear completely open, the entire universe would be destroyed. The only thing they can achieve after a hundred years of research is the applied technology that will later lead to the “phase armor.” However, this technology will become the driving force behind reviving the decaying Earth into a new nation, Dezarium.
3100 A.D.
• By covering the remaining ships with phase armor, new ships such as the Goruba and Pleiades classes are built one after another. These are feared as the “dark fleet” because of their color. Earth, renamed Dezarium, rapidly gains prominence among the interstellar nations.
• However, no method has yet been found to close Saturn’s space rift, and observations imply that a great collapse will occur within the next hundred years.
• Around this time, research on a “space-time node,” which is hypothesized to exist deep inside the rift, is also progressing, and the possibility of time travel is being explored.
• After half a century of research, the existence of the space-time node is confirmed, and after several unmanned explorations, a manned exploration is carried out. As a result, it is discovered that the other side of the space-time node is near the center of the galaxy, more than 40,000 light years from Earth. That was about one hundred years ago.
3198 A.D.
• There is only one space-time node, and you cannot choose the time you want to go back to. Also, once it is fixed at a certain point, the time axes of “this side” and “the other side” are also fixed in sync with each other. For example, if a tunnel leading to 2204 is opened in 3197, in 3198 it will go to 2205, and in 3199 it will go to 2206, and time will flow the same way in both spaces. Using phase technology, Dezarium fixes the space-time node leading to the early 2200s and makes the first attempt to obtain something from the world of a thousand years ago with minimal disruption of history.
• Iscandar is their goal; a legendary planet that disappeared a thousand years earlier in the explosion of the planet Garmillas, which was destroyed in the war with Bolar. It is said that the Cosmo Reverse System there once saved Dezarium when it was called Earth. If so, is it possible to save the home planet from the current crisis as well?
• Based on this idea, a plan is put into action to acquire and save Iscandar, which is destined to disappear.
• A year after the space-time node is fixed, the Meldarz fleet of the Dezarium military sets out for Iscandar, time-traveling to the year 2205. First, they destroy the planet Garmillas, which was destined to be destroyed anyway, and succeed in freeing Iscandar from the yoke of gravity. All that remains is to tow it with the automated planet Goruba through the space-time node and bring it to 3199. But an unexpected factor awaits Meldarz.
• The fleet of the Earth military from that era and the remaining Garmillas forces launch a fierce battle, blocking the transport of Iscandar. This unexpected resistance results in the annihilation of the Meldarz fleet, and Iscandar’s self-destruction leads to the worst case scenario.
• Even though Dezarium has a time tunnel that leads back a thousand years, time is synchronized and therefore irreversible. With no way to obtain Iscandar any longer, Dezarium decides on a major change of policy. That is, they will tell the truth to Earth a thousand years ago and change the history that followed. From that point on, they would repair the spatial rift on Saturn, provide technology (including phase technology), and avoid the tragedies that would otherwise accumulate over the next thousand years.
• Large-scale interference with history; as a result, the Dezarium people of 3199 will either continue to exist as a branched parallel world, or disappear.
• AI Dezarium points out that the latter is more likely, but the Dezarium people don’t think this matters. In any case, the universe of 3199 will disappear in the near future. If they can avoid this tragedy by disappearing, by entering a new millennium as human beings with flesh and blood, not machine bodies, then that is their true wish; the dream of Dezarium, which was tossed about by a cruel fate and forced them to give up being human.
3199 A.D.
• A bridgehead, including an intermediate supply base, is built in the space of 2206, and a large fleet sets off for Earth. A communication sent to the Earth government in advance is ignored, but several staff officers who feel a sense of crisis about the future become sympathetic and a plan is made to compromise Earth’s defense network.
• Eliminate resistance and temporarily control Earth. If we speak sincerely, the people of Earth will understand. If they cannot understand, there is no other way but to activate the Hyperon Bomb sent to Earth disguised as a tool for space repair. This will connect the brains of all human beings on Earth to AI, and transform them into Dezarium. They will no longer be purely human, but as long as they think like us, they can maintain their flesh and blood bodies.
The Dezarium know that excessive ego and freedom will lead to division and destruction. If the people of this era lack the ability to self-reflect, then controlling their minds is inevitable.
• At the same time, Dezarium has another plan in progress: to obtain the “fragment of Iscandar” that exists in 2206.
• If they can bring it back to 3199, they may be able to restore Iscandar’s technology and prevent the spatial tear. The secret mission of the Dezarium AI, which is only conveyed to a select few high-ranking officers, informs them that there are two fragments of Iscandar.
• One is Starsha, the Iscandar biological management program, which reproduced herself by obtaining the element of an Earthling — Sasha. The other is the last pure wave core generated on Iscandar, which can only be activated on Earth and can only be unlocked by Earthlings. The ship that carries it is the space battleship Yamato.
• Yamato is the flagship of the resistance fleet that wiped out the Meldarz fleet, and already had a fated connection with Dezarium. Because of that connection, the crew of Yamato decides to rebel against Dezarium.
• They witnessed the ruthlessness of the Dezarium army when they destroyed the planet Garmillas; their machine-like, inorganic, merciless way of fighting. Even if they are future humans who had no choice but to survive in that way, even if their actions came from a selfless spirit to avoid destruction, the crew of Yamato is not prepared to take Dezarium’s words at face value.
• Foreseeing the Dezarium attack, Yamato and Sasha are hidden in the Icarus Observatory in the asteroid belt. The Yamato crew, who escape from Earth under occupation, gather at Yamato, which has undergone a major modernization in preparation for a war against Dezarium. They cannot accept these “people,” who would connect all of humanity to machines using a Hyperon Bomb if necessary, as saviors from the future. They head for the space-time node at the center of the galaxy, the home base of the Dezarium AI that controls everything — Earth, a thousand years in the future.
Fleeing the pursuit of the Dezarium army, Yamato sets off on her fourth voyage.
