PostSubject: The Aurelian Kh'uunate: Timeline   Sun Nov 11, 2012 4:31 pm


 As a note to the reader, it should be recognized that different alien species use different calendars: From the Old Terran Gregorian calendar to the Altair solar-cycle chart, no two calendars of isolated origin are ever the same. This holds true for the Aurelian calendar-year, where one Aurelian year lasts 288.501 Aurelian days, and where one Aurelian day is roughly 25.02 Terran hours. Caution is advised when converting Aurelian years to Galactic Standard Time.

Years are measured with reference to the KZX (Kh'uunate Formation Time). AKZX stands for "Before Kh'uunate Formation Time" whilst PKZX represents "After Kh'uunate Formation Time."


Est. 10,000,000,000 AKZX (7,898,000,000 BCE)- Gol'Azkhor, an orange dwarf of hydrogen-based composition and carbon-rich star dust, forms from the collapse of a mid-sized nebula left over from a preexisting red supergiant. Subsequent planetesimal impacts over tens of millions of years forge a proto-planetary cloud which is rich in organic compounds.

Est. 6,000,000,000 AKZX (4,739,000,000 BCE)- Evaporation of dime-volume black holes in the Odwin system results in a surplus of electromagnetic radiation which ionizes its segment of the now-extinct nebula; the twin red dwarfs characteristic of Odwin are born.

Est. 5,824,000,000 AKZX (4,600,000,000 BCE)- The star system mentioned by so many sentients as the Sol System is born in the Orion Arm of the Milky Way Galaxy. Over the next hundreds of millions of years, the present-day planets of the Sol System form from planetesimals as the Bombardment phase drones on into the Archaen Era.

Est. 5,142,000,000 AKZX (4,064,000,000 BCE)- After 4.8 billion (Aurelian) years of steady mass accumulation and temperature cooling, Gol'Azkhor Prime assumes a thick, soupy atmosphere rich in nitric acid and carbon monoxide; tens of millions of years of subsequent solar desiccation lyse the nitrous and organic compounds which recombine into present-day hydrogen cyanide. Oxygen released from the desiccation seeps into the earth and reacts with silicon-boron ores. Eventually, the first organic polymers characteristic of life arise in the dwindling pools of nitric acid as the first unicellular lifeforms evolve.

Est. 4,182,000,000 AKZX (3,303,000,000 BCE)- Abiotic genesis gives way to Darwinian-like natural selection as a mixture of hydrogen cyanide, methane, and elemental nitrogen accumulates in the middle atmosphere- choking off ionizing radiation to extremophilic microorganisms which had relied on the high-energy collisions of UV radiation to power rudimentary respiratory reactions. A mass-extinction event occurs which wipes ionizing radiation-dependent life off the face of Gol'Azkhor Prime, leaving behind mundane photosynthesizing autotrophs and heterotrophs to struggle for domination over the planet.

Est. 3,441,000,000 AKZX (2,718,000,000 BCE)- Hydrogen cyanide and methane are within five percent of the present-day 78.26 cyanide-methane atmospheric composition due to the relative ease at which the Gol'Azkhorzi storms decomposed the carbon monoxide, providing ample carbon to bind with the nitric acid to produce cyanide. This triggers forth a rapid diversification of heterotroph cells as cyanide-hungry cells form biofilm communities on dry land. Sublimation of oxygen via cellular metabolism releases minute quantities of water vapor into the anthropocidal atmosphere. By this time, a second wave of mass extinctions occurs as the last nitric-acid pools disappear, leaving behind land-dwelling organisms to dominate the landscape.

Est. 1,775,000,000 AKZX (1,402,000,000 BCE)- Following a long, arduous recovery of biodiversity, the biofilms return to pre-extinction levels as they compete for limited space; though much of Gol'Azkhor remains barren, the few swaths of biofilms which do exist are evolving into lichen-like bioluminescent methanotrophs; this split in respiration will eventually lead to a hydrogen cyanide-producing autotroph class and a cyanide-removing heterotroph class which- together- initiate a cyanide cycle for the planet.

Est. 796,000,000 AKZX (600,000,000 BCE)- [b]The Aurelian analog of the "Cambrian Explosion" unfolds as unicellular autotrophs yield increasing tracts of land to non-vascular methanovores. These are the first multicellular organisms visible to the naked eye as an iridescent-teal glow emerges among Gol'Azkhor's crust: Subsequent growth in cyanide-consuming heterotrophs yields to an evolutionary split between fungi-like organisms that feed on dead organic tissue and animal-like cells which continue to form into products of increasing cellular complexity.

Est. 600,000,000 AKZX (545,000,000 BCE)- Accelerated evolution continues after Gol'Azkhor's surface is increasingly buried beneath undergrowth; ground-hugging autotrophs start to break up the topsoil as increasing sophistication of acidic compounds enable the methanovores to burrow deeper into the silicon-rich crust. Button-sized, trilobite-like animals armored with chitin inexplicably appear after generations of mutations which transform a yet-to-be-identified ancestor into the first shelled land-dwellers. Riverbeds remain dry, though.
 Sector Zeta-Phi is mysteriously formed when two lead-rich nebula condense into two red dwarfs with revolving planets of plumbum-rich composition.

Est. 525,400,000 AKZX (415,000,000 BCE)- [b]The Aurelian parallel of the Cambrian Explosion occurs after one crucial event occurs: The return of liquid nitric acid. This steady downpour of nitric acid helps to refill the riverbanks to their former glory (Discounting plate tectonics, of course.) and also assists in providing habitats for aquatic plants and a new phylum: The chitin-jawed fishes.
 This return of nitric acid, however, not only returns water ions to the surface but also starts to release trapped oxygen and hydrogen beneath the Aurelian crust as the acidic rivers eat away at the metallic ores which exist in the "oxygen table." Gains in biodiversity are short-lived after the pace of nitrate expulsion starts to intoxicate the atmosphere, leaving behind only five percent of all species to survive. The button-diameter, chitin-shelled organisms presumably go extinct after just a Terran decade of nitrate-precipitate downpours.

Est. 462,112,000 AKZX (365,000,000 BCE)- The rate of precipitation of nitric acid drops a tad bit after the refinement of vascular tissue bears witness to record-shattering altitudes of earlier fern-like plants as the cellulose-equivalent, carbon-fiber, starts to support taller plants. Nitrates building up from the decomposition of nitric acid greatly assist in providing quick, long-term nourishment for these true trees.
 A mysterious  communications probe makes impact with Odwin Prime. Composed of durable carbon-boron nitride nanotubes interlaced in a permanent shell, this probe will remain untouched in an iron-silicon sand dune until 2,247 AKZX (1,475 BCE), when determined Aurelian explorers discover the metalloid remnants some twenty Terran years after arrival.

Est. 312,120,000 AKZX  (246,530,000 BCE)- The Age of Phot'unin (Trees) begins with an explosion of flora which, in turn, nourish a steadily-increasing diversity of species which survived the nitrate-precipitate downpour. The levels of hydrogen cyanide and methane remains within two percent of the present-day level with no dramatic variations.
 Evidence of terraforming in the Gilxocie system shows a sudden, century-long surge in the levels of carbon dioxide and nitrogen from an earlier composition favorable to present-day Aurelian life forms.

Est. 209,230,000 AKZX (165,200,000 BCE)- The return of animal life on Gol'Azkhor Prime also witnesses the Age of Aut'hunin (Insects); a geological era characterized by the rapid dissemination of pro-flight genes as land-dwelling critters continue to fragment into the present-day insectoids and Hyd'hatin (Amphibians).
 The first attempt by an exo-sectoral entity- the sagacious, lupine V'erl- to colonize the Aurelian sector occurs when a metal-clad V'erl jettison pod rams into the acrid, pestilence-rife surface of the swamp world M'lari II to identify the atmospheric composition. The results come up negative, however, for the plausibility of colonization due to toxicology-related concerns of the V'erl and thus colonization of the sector is discontinued. Exact dates of arrival are unknown, though, for a subsequent nuclear war on the V'erl home world results in another loss of knowledge.

151,927,301 AKZX (119,999,904 BCE)- Earliest verifiable date;
 Another deep-space probe the length and width of a seaward skiff arrives in the Aurelian system with a solar-powered transceiver which repeats a signal in intermittent 3-second periods for ten years. Remaining in one of Gol'Azkhor's Lagrange points rather than plunging down to the surface, the probe remains relatively unscathed until the first Aurelian expedition discovers a cache of what are later determined to be collegiate-tier calculus equations concerning the surface areas, volumes, and derivatives of organic forms. These will greatly assist with Aurelian breeding programs determined to maximize surface area- and carrying capacity- of biological ship components whilst minimizing dead weight in the airframe. The species who sent the probe are never identified and are presumably extinct.

Est. 82,923,000 AKZX (65,000,000 BCE)- On Old Terra, the K-T event is assumed to have occurred.
Aurelian flora continues to boom along with the rise of Chitin-shelled quadrupeds, reptile-like creatures of canid proportions which prey upon various insectoids in the great Aurelian rainforests. Nitric acid concentrations in the rivers meet close to present day levels within a variation of 0.296 percent.
 In addition to the quadrupeds are the Aet'hulin, or the first truly-remarkable flying animals built like Terran man-o-wars. Originating from a soft-bodied insectoid bearing an internalized air bladder, the Aet'hulin expand rapidly such that, by the end of the Age of Aet'hulin, they float high in the Aurelian stratosphere with proportions comparable to Terran football fields.
