• The Furies hold a significant presence across local space — including some level of domination of early Human, Andorian, Vulcan, Klingon, and Ferengi cultures, serving as the source of a number of myths and legends. (Novel: "Invasion!" series)
  • Part of this domination may have included genetic experiments upon the natives of Qo'noS to transform them in their own image, including the development of their biological redundancies and the genetic abnormality later known as the JoH'a mu'qaD. Due to this, their place in Klingon mythology otherwise, and the similarities of both them and the victims of the JoH'a mu'qaD to the figure known as Fek'lhr, they may have been the source of the original myths of the Klingon gods as a whole, suggesting that legends of their banishment were distorted over the years to the modern story of the Klingons slaying their gods.

14th century

• The Hur'q, a domineering and vicious alien species native to the Gamma Quadrant, invades Qo'noS as part of a long-term sweep across the Beta Quadrant, intending to subjugate the Klingons and plunder their homeworld of resources and treasures. While many artifacts are stolen, including the Sword of Kahless, the Klingons manage to repel the invasion, jumping from basic land transport directly to warp travel as a result of captured technology. (DS9: "Sword of Kahless"; TLE Novel: The Art of the Impossible)
  • Following the departure of the Hur'q, the Klingon hero Ch'gran uses captured Hur'q facilities to construct a fleet of seven vessels with which to conquer the heavens, to ensure the invasion could not be repeated. Departing exactly one year after the departure of the Hur'q, the fleet is lost shortly after communicating the discovery of the first world to be taken by the burgeoning Klingon Empire, its fate unknown. (TLE Novel: The Art of the Impossible)
    • Wreckage in the Betreka Nebula discovered in the 2290s revealed that Ch'gran in fact planned to conquer worlds purely for his own benefit and use their resources to eventually conquer Qo'noS itself, his plans upended only by the mutiny of his subordinate captains, leading to the destruction of the fleet. This fact was suppressed by Chancellor K'mpec and Imperial Intelligence upon its discovery, so as to preserve the legend. (TLE Novel: The Art of the Impossible)

(TOS Novel: The Rise and Fall of Khan Noonien Singh, Volume 1)

1970s

1974

• The Great Khanate rises in the remote deserts of Chandigarh, India, Earth, led by the self-proclaimed Khan, Noonien Singh. Despite the efforts of India to suppress his rule, immense popular support prevents the Indian government from taking direct action. Still, little attention is given to him outside the country, seen as nothing but a trivial local warlord. Across the world, other powerful, charismatic, and somewhat unbalanced figures begin to draw followers to themselves in various nations, including Randall "Hawkeye" Morrison, leader of the Army of Eternal Vigilance, an anti-government militia based in Arizona; Chen Tiejun, founder of a separatist matriarchal colony off the coast of New Zealand; Elijah Amin, one of the most influential warlords in Somalia; Vasily Hunyadi, a highly-placed figure in the Yugoslavic civil wars; Alberto Gomez, leader of a Peruvian rebel army seeking the reformation of the Incan Empire as a Marxist state; and Brother Arcturus, founder of the suicide cult known as the Panspermic Church of First Contact. To the international community, these figures seem disconnected and unrelated, mere blips amidst the worldwide chaos of the late 20th century. (TOS Novel: The Rise and Fall of Khan Noonien Singh, Volume 1)

1990s

1992

• Following the failure of uniting his brethren in the name of world conquest, Khan Singh instead decides to seek war against them.

(TOS Novel: The Rise and Fall of Khan Noonien Singh, Volume 2)

1996

• The Eugenics Wars end following the revelation to the world's nations of their existence. Most Augments are thought killed in the aftermath, though a number of partially-developed augmented embryos that survive the various bombing campaigns in a state of medical stasis are captured by the nations of the world, unsure what fate they deserve. Ultimately, these embryos are consigned to a number of secure cryonics stations dotting near-Earth space. Following the revelation of the Eugenics Wars and the chaos the Augments brewed across the world in their deigns for conquest, the nations of Earth ban genetic augmentation and genetic engineering of humankind.

Late 2010s

• Even as the technological developments of the human species seem to continue unceasingly, the nations of Earth fall into further chaos, possibly still suffering the aftermath of the international manipulations of the long-since defeated Augments. Civil unrest broils worldwide as a result of global economic and environmental turmoil and growing poverty and unemployment, concentrated especially in western Europe and the United States. The United Nations collapse under the weight of the growing global crises. (TNG: "Encounter at Farpoint")
• In the United States, poverty had grown to such a degree that the Employment Act of 1946 was repealed, the Federal government abandoning any claim towards ensuring the employment and economic stability of its citizens. As an alternative, most major American cities instituted “Sanctuary Districts”; intended to be neighborhoods devoted specifically to providing homes to those without the means to obtain them otherwise, these districts soon degenerated into nothing more than massive outdoor debtors' prisons. Similar measures were seen in other nations as well, with many governments choosing to hide their poverty-stricken citizens away rather than address the underlying issues responsible for their state. (DS9: "Past Tense")
• To help stave off the growing economic troubles, the Eastern Coalition (ECON) is formed, an alliance of various Asian states largely dominated by the People's Republic of China, but also including India, Pakistan, Iran, Kazakhstan, Vietnam, and Singapore as members. As a demonstration of dominance, the ECON's space agency manages a successful manned return to the moon before any of the more dominant space agencies can accomplish such. (TLE Novel: The Sundered; TOS Novel: The Rings of Time)

2018

• Due to the discovery of internally metered pulse drive technology (also known colloquially as "impulse drive"), allowing travel time to nearby planets to be cut from years to months, sleeper ships are slowly phased out of Earth production. Many DY series ships are still en route to their destinations, overtaken by newer vessels.

2020s

2020

• The first successful manned mission to another planet in the solar system is completed, with NASA astronauts Christopher, Fontana, and O'Herlihy arriving at Saturn in the UNSS Lewis & Clark in a mere three months thanks to recently-developed impulse drive technology. This mission is intended largely to recover face lost by the ECON's moon launch, but also to analyze the recent odd deterioration of Saturn's rings and increasing activity of its renown hexagonal polar storm. (TOS: "Tomorrow is Yesterday"; TOS Novel: The Rings of Time)

2024

• Following decades of political violence and strife, Northern Ireland leaves the United Kingdom and reunites with Ireland. (TNG: "The High Ground")

(DS9: "Past Tense")

2026

• The global destabilization of numerous nations leads numerous bands of eco-terrorists upset at the mismanaging of Earth's biosphere to strike out at the weakened nations, leading to the deaths of 37 million people across the globe. In response to these attacks, the New United Nations (NUN) are formed, seeking progress towards a true United Earth. The ECON refuses to pursue membership in the NUN, seeing it as merely further attempts at re-asserting Western dominance. (ENT: "In a Mirror, Darkly, Part II")
