Summary: If evidence of a civilization's presence disintegrates after 10,000 years, and the earth is 4.55 billion years old, what might have transpired throughout the earth's history that we are unable to detect? This is the history of the earth by way of Delta Green.
|This is from an older edition of Delta Green but God do I like it|
A brief description of what the Delta Green RPG is about:
A pair of competing, illegal conspiracies within the federal government that have their operatives steal funds and equipment from their employers so that they can wage war on barely-understood, sanity-destroying manifestations of supernatural phenomena, ideally under the cover of sham federal investigations but more likely working the case at night or going AWOL if necessary. Both conspiracies are known as Delta Green. The players are in as much danger from federal prosecution, having their families disintegrate with a divorce stripping them of their assets and sanity-preserving social circle, and of liquidation by the conspiracy should they become too unhinged as they are from having their atoms reassembled at random by mistiform static, getting dirked down by the relict cultists of an aeons-old protohuman empire, or getting eternally trapped in a transitory time-realm.
“Current human industrial civilization emerged, flourished, and bids fair to destroy or smother itself, all in only a few millennia. It takes geological and atmospheric processes approximately a thousand years to erase most signs of human construction: even plastics and metals corrode and disintegrate after five or ten thousand years. Continents subside, volcanoes erupt, coasts flood, glaciers grind down. A few megaliths survive perhaps, washed clean of the carbon we require to pin them in historical time.
Homo sapiens has existed for about a quarter of a million years. The emergence and destruction of previous civilizations is all but a mathematical certainty. Delta Green often uses the same names 19th century occultists and charlatans ascribed to these pre-decedents: Mu, Lemuria, Uluumil-Naga, and so forth. Other names appear in older records: Lomar, Mnar, Thule, Yhe, Hyperborea, and Valusia. Names and histories come adrift: one tradition asserts that Hyperborea was a human country in Eurasia contemporaneous with the Classical Greeks, while another describes it as a lost polar continent inhabited by furry humanoids or sweat-born golden beings that reproduced by budding
The cod-scholarly habit of applying human and historical mythical terminology to ancient and inhuman empires further muddles the issue: “Hyperborea,” for example, merely means “above the North Wind,” implying only a vaguely Arctic location. The constructions of the truly ancient alien races who colonized the Earth often pay no more heed to human notions of physics and temporality than their masters did: thermoluminescence, carbon dating, and all other methods of fixing a fossil or artifact in time apply only fitfully to unnatural relics. Finally, of course, the questions of time travel, dimensional dilation, and temporal epistemology raised by unnatural contact imply that even simple notions such as “before” and “after” have almost no real meaning to these alien civilizations.
With all that said, however, here’s what a paleontologist and an occultist might piece together if Delta Green were ever foolish enough to allow such a team access to their remaining files and incident reports. To date, no one has ever done so. Dates derive from current paleontological and paleogeological research; they are necessarily approximate and, as usual, may be wildly inaccurate.
∆ 4.48 billion years ago: The Hounds of the Angles are thrown into the corridors of time. (Moon formed by the collision of a Mars-sized sphere with the proto-Earth.)
∆ 542 million years ago: The crinoid Elder Things arrive on Earth, seeding millions of species with their experiments and bioculture. (Cambrian Explosion.)
∆ 443 million years ago: Spectral polyps arrive or emerge. (Ordovician Extinction.)
∆ 378 million years ago: Great Race of Yith arrive and uplift a conical terrestrial species; the Yithians conquer and imprison the spectral polyps. (Devonian Extinction.)
∆ 359 million years ago: Cthulhu and its spawn arrive from Zubeneschamali (Beta Librae) or Sothis (Sirius, sometimes referred to as Zoth). (Hangenberg Event; algal blooms flood the oceans, choking off life across the Southern Hemisphere.)
∆ 300 million years ago: R’lyeh sinks, Cthulhu trapped; N’Kai founded by refugee servitors of Cthulhu. (Pangaea forms.)
∆ 252 million years ago: The shoggoths rebel against their Elder Thing masters, unleashing a global war fought with ecocidal weapons. By the time the Elder Things subjugate their slave creations, the war has driven 96% of all species on the planet extinct. (Permian Extinction.)
∆ 230 million years ago: Serpent people evolve, or are created by Yig; they rule the empire of Valusia roughly where the Mediterranean is now. (75 million years after the first reptiles evolve.)
∆ 184 million years ago: Mi-Go arrive on Earth in force from Yuggoth or further Outside, defeat the Elder Things and restrict them to the Antarctic. (Pangaea breaks up.)
∆ 145 million years ago: In some legends, the Mi-Go bring Ghatanothoa to a Pacific subcontinent (“Mu”), possibly as a weapon.
∆ Deep Ones bring Byatis to Valusia, likewise. (Tithonian extinction event.)
∆ 90 million years ago: Mi-Go drive the serpent people underground to Yoth. (Fossils of Najash, a bipedal, burrowing snake with a pelvis.)
∆ 66 million years ago: The spectral polyps escape their prisons—possibly by summoning an enormous iridium-iron asteroid—and drive the Great Race from their rugose cone-bodies and into the future. The cataclysm destroys most Elder Thing cities, leads Mi-Go to reduce their presence on Earth. (Cretaceous Extinction.)
∆ 50 million years ago: Prehuman civilization (“Lemurians”) flourishes in Asia or a parallel dimension (“Shamballah”).
∆ 33 million years ago: War between Lemurians and Deep Ones destroys Lemuria, drives deep ones into deep trenches. (Meteoric bombardment of eastern North America; Eocene-Oligocene Extinction)

∆ Tsathoggua arrives in Hyperborea from N’Kai or Saturn.
∆ 2.54 million years ago: Lloigor arrive from the Andromeda Galaxy, colonize Mu, begin to enslave and engineer hominid stocks. Some sources say the Lloigor faced resistance from Ghatanothoa; others, that Ghatanothoa was chief among them, or perhaps a forerunner. (SN 1885A, only known supernova in Andromeda Galaxy, c. 2.54 million light-years away)

∆ 173,148 BCE: Worship of Ghatanothoa becomes supreme in Mu.
∆ 110,000 years ago: Uluumil-Ra empire of Mu destroys remnant Lemurian cities in Asia. (Last Gigantopithecus fossils.)
∆ 100,000 years ago: Human kingdom rules the continent or dimension of Atlantis; shadow war against serpent people infiltrators eventually undermines it.
∆ 85,000 years ago: Itla-shua destroys Hyperborea and the final Elder Thing city with ice; Lomarians retreat into K’n-Yan, except for those in the capital city of Olathoë. (Wisconsin Glaciation.)

∆ 50 million years from now: Great Race of Yith returns to incarnate into a hardy coleopteran species, reconquers the Earth.”
If you look into the game, look for the Lloigor, the most fascinating energy-field subterranean cancer-inducing space tyrants in role playing gaming. Unbelievably, this game also nails a lot of content related to the culture in the government, military, intelligence community and special operations IMO, so if you’re in or adjacent to one of those fields look for that.
Here are my notes, which I love and may put in a post in the future.
