Giants (series)

• 25 million years ago: Intelligence arises in the Solar System on the planet Minerva, in the form of the "Giants". Minerva is orbited by one moon and orbits the Sun between Mars and Jupiter.
• Between 25 million and 4 million years ago: Carbon dioxide levels in the Minervan atmosphere begin to rise. As the Giants have a low tolerance for carbon dioxide, they send a scientific team to the star Iscaris to perform experiments to aid in their understanding of the situation. However, the experimentation destabilizes the star, causing a nova. The team attempts to flee on their starship Shapieron which is unable to decelerate (due to a problem with the ship's main drives), forcing them to orbit the Solar System at relativistic velocities, experiencing one year for every million that pass. After the events at Iscaris, the Ganymeans bring in animals and hominids from Earth in the hope of isolating the gene responsible for carbon dioxide tolerance. However, they fear the effects of using this gene in themselves and are forced to flee to the distant planet of Thurien, in orbit around the "Giants' Star". They leave behind relays so that they can continue to observe Minerva and their evacuation is mostly successful, though one of their ships crashes on Ganymede.
• Approximately 100,000 years ago: hominids left behind on Minerva after genetic experimentation evolve into the Minervans—modern humans.
• Between 100,000 and 50,000 years ago: An ice age begins on Minerva, threatening to destroy the new human civilization. Humanity begins a space program in an attempt to escape the planet and migrate to Earth. This leads to conflict and an arms race between the inhabitants of Minerva's two continents, democratic Cerios and autocratic Lambia, over control of the program.
• From 50,020 to 50,000 years ago: The Jevlenese Imares Broghuilio and his generals appear via a time loop from the future in a fleet of five starships. Cerian president Harzin and Lambian king Perasmon declare the end of the arms race and the demilitarization of the two continents. Prince Freskel-Gar Engred is secretly aided by the Jevlenese in his plan to assassinate Perasmon and Harzin, and ascends the throne of Lambia. Under his rule, military development is restarted with contributions from Jevlenese technology. Broghuilio removes Freskel-Gar and installs himself as dictator, renaming himself Zargon. In turn, he too is replaced by Xerasky.
• 50,000 years ago: After years of hostilities, total nuclear warfare finally breaks out between Cerios and Lambia on Minerva and at the Cerian base on Minerva's moon. The Thuriens intervene but are too late: Minerva is shattered, forming Pluto and the asteroid belt while its moon is captured by Earth—which originally had no moon—becoming the planet's familiar satellite. The Cerian survivors ask to be transported down onto Earth but the gravitational stresses of the Moon being captured by Earth throw their civilization back to the Stone Age and, to survive, they are forced to wipe out the native Neanderthals before attempting to rebuild. The Lambian survivors are resettled on the planet of Jevlen, near Thurien, in an attempt to reintegrate them into society. They set up the supercomputer of JEVEX to run their affairs, modelled after the Thurien computer VISAR.
• C. 50,000 years to the 19th century: The Jevlenese move JEVEX to the planet of Uttan so that their researchers can increase its power without the knowledge of the Thuriens. Unknown to both parties, a pocket universe forms within JEVEX, the Entoverse. Some of its sapient inhabitants ("Ents"), who go by the title of ayatollahs, devise the ability to pass over to the original universe by taking over the minds of the Jevlenese. The Thuriens begin to trust the Jevlenese and contract them with the task of observing human civilization. Still driven by hatred of their old rivals, the Jevlenese set about hindering human progress.
• 19th century: In their attempt to destroy humanity, the Jevlenese begin to promote weapons research. In 1831, the Ent Sykha founds the Spiral of Awakening cult.
• From 1939 to 1945: The Jevlenese orchestrate World War II, believing that it will result in mutual nuclear annihilation.
• Post 1945: Earth begins a nuclear arms race after World War II, in accordance with the Jevlenese plan. Meanwhile, the Jevlenese leaders secretly build up their own stocks of weapons.
• 1979: Birth of Joseph B. Shannon.
• 1992: Birth of Victor Hunt.
• 1999: Birth of Lyn Garland and Duncan Watt.
• 2002: Birth of Hans Baumer.
• 2015: With the looming threat of the Nucleonic bomb, the Cold War ends and the United Nations Space Arm (UNSA) is formed to promote peace and stability. Jevlenese agents help to demilitarize Earth, though to isolate Thurien they continue to claim that Earth is on the brink of World War III.
• 2027: Humanity begins to explore space once more. A UNSA mission finds a 50,000-year-old Cerian corpse, nicknamed Charlie, on the Moon. Scientists Victor Hunt and Christian Danchekker investigate the "Lunarians" (beginning of Inherit the Stars).
• 2028: The former existence of Minerva is deduced. UNSA Expedition Jupiter 4 discovers the crashed Giants' starship on Ganymede and name the race the "Ganymeans".
• 2029: Humanity reconstructs the full story of the Lunarians and the Ganymeans, discovers that the Moon was once Minerva's moon and finally realizes that Earthmen are the descendants of the Lunarians originating on Minerva (end of Inherit the Stars).
• 2030: The crew of the Shapieron have slowed down and re-enter the Solar System where they contact Humanity. They stay for six months but, rather than be alone in the universe, they set out once more to find the "Giant's Star". Humanity learns that their intelligence was an unintentional byproduct of the unsuccessful genetic experimentation of the Giants. The Jevlenese observers decline to inform Thurien of the reappearance of the Shapieron. Thurien learns of the Shapieron from a radio message sent by Earth (events of The Gentle Giants of Ganymede).
• 2031: Unbeknownst to Jevlen, the Thuriens make radio contact with Earth and uncover the Jevlenese deception. Earth and Thurien unite against Jevlen, switching off JEVEX. Imares Broghuilio and his generals attempt to escape from Jevlen but are accidentally transferred into the past of another segment of the Multiverse, near the Minerva of 50,020 years before, in the process proving the Many-worlds interpretation. This discovery allows the Thuriens to begin to investigate the possibility of cross-Multiversal transfer. The now free Jevlen is on the brink of becoming a peaceful society when the deactivation of JEVEX causes the Ents to attempt an escape from the Entoverse. The ayatollah Eubeleus travels to Uttan, planning to switch JEVEX back on so that the Ents can flood into Jevlenese minds but is stopped by a coalition of humans and Thuriens, who isolate JEVEX on Uttan, preserving the Entoverse (events of Giant's Star and Entoverse).
• 2033: Victor Hunt is contacted by a version of himself from another segment of the Multiverse. A group of Terran and Thurien scientists invent the Multiporter, enabling cross-multiversal travel. (beginning of Mission to Minerva)
• 2034: The Terrans and Thuriens on the Shapieron multiport to the 50,020-year past of the alternate universe in the Minerva Mission, an attempt to prevent the destruction of Minerva in that segment of the Multiverse and to initiate a new line of history. The Mission to Minerva proves successful and the Shapieron returns to its own universe (end of Mission to Minerva).

Events in this alternate chronology are identical up to 50,020 years ago. In this chronology, the Minerva Mission used timeline lensing generated by the Shapieron to cause the Jevlenese to disappear from the alternate timeline universe without a trace. Cerios and Lambia gave up the conflict and disarmed to concentrate on a space program for their mutual benefit. The Shapieron then returned to its own universe.
