Sapient life, descended from gorgonopsians, after a chance wandering in the shrubland of Gondwana that isolated them several million years before, evolves shortly (some 90,000 years) before the Permian Extinction, which wipes out 95% of all life on Earth, like that extinction does in OTL (it is the biggest extinction ever to strike Earth). Civilization arises 11,000 years before the extinction, starting near the mountains in the middle of the Pangaean supercontinent. By the time of the extinction, airplanes fly the skies over the Paleo-Tethys Ocean from and to the lands surrounding it and the larger Panthalassic Ocean is being explored, and there is a high level of technology. Then the Siberian Traps eruptions begin anew, releasing great clouds of methane (thus triggering the extinction)... how will the people react?

Date System and brief history Edit

File:Natives of Permian Extinction Civilization Earth.JPG

For simplicity, at first, the time frame will be dated based on the start of the extinction (that is, the start of the eruption span that results in the extinction). The Siberian Traps apparently erupted over hundreds of thousands of years; however, this is great enough a time span for evolution to occur, and the eruption may have been sporadic, occurring at various points over that long time period. (For comparison, the OTL human species is only 100,000 years old, and we're looking back 250 million years, so the apparent time span of the eruption may itself be greatly exaggerated.) The POD therefore occurs sometime after a phase of the Siberian Traps eruptions, in which climate change has caused an evolution of certain dicynodonts into intelligent beings, and the civilization takes about 90,000 years to start after the advent of sapience, with relatively minor eruptions from the Traps here and there. One particular eruption reduces the population and thus creates diversity through a genetic "bottleneck", so there are dicynodonts of various races. (The analogue is the Lake Toba supervolcano of OTL.)

The great eruption that causes the extinction in OTL comes some 12,000 years after civilization begins, spilling carbon dioxide into the atmosphere and causing gas hydrates to erupt from the Arctic waters after the earth gets warm enough. Therefore, the start of sapience is 102,000 before the extinction, and the start of civilization is 12,000 before the extinction. 15 years before the extinction, a series of earthquakes shake the already existing Siberian Traps area, in the Land of the Temples, which has various religious rock carvings (a la OTL's Deccan Traps) dating back hundreds of years, perhaps thousands of years. A tsunami results, devastating areas around the Paleo Tethys ocean and killing something like 100,000 people. Folks pick up after the disaster and go about everyday business. Nine years before the extinction, another earthquake shakes the area, sparking landslides, and, more importantly, sparking the formation of a fissure underground (unseen by people on the surface). Two years before the extinction's start, harmonic tremors are detected under Siberia, prompting an eruption warning and sparking the greatest peacetime evacuation in the history that they know.

A few months later, a huge eruption devastates a port town in the Siberian Traps area, and chains of volcanoes in the vicinity start to rumble, producing pyroclastic flows and enormous clouds of ash. However, this is not the main eruption: the Siberian Traps are composed of lava flows, not ash, after all, and thus this is just a prelude to the main show. Eruptions continue off and on for another couple of years, all over the continent of Siberia, and a huge, long fissure opens up, through which the upwelling of a great pool of magma suddenly gushes, like bleeding from a stab wound. It doesn't stop: more fissures open up, and more, and more. Twenty years into the extinction, civilization is still thriving, but the Earth's temperature has started to climb markedly after a dip, and clouds of ash are causing regular havoc with airplane flights and everyday business. Three hundred years into the extinction, substantial portions of the icecaps have melted, and water vapor and drowned shorelines are common phenomena. However, even five hundred years into the extinction, the effect is barely noticable, and wars and trade continue going on because the main impact of the extinction has been in the Siberian and South Chinese continents.

At this point, in a steamy, warm world, the methane hydrates near the poles begin to evaporate, provoking enormous "burps". The methane converts to carbon dioxide, which contributes to warming, and temperatures, already on the rise, shoot up at alarming speed. So does the rate of ice melting at the poles (particularly the South Pole, which is closer to land). Acid rain, already a major problem, becomes worse. The oceans become so warm that there is no exchange of cool and warm water between the top and the bottom, and this stagnation (along with acid rain) causes a crash in seafood stocks, with numerous animals becoming extinct in the seas (and even on land) some 520 to 570 years into the extinction. People retreat to protective shelters as the vicious cycle of eruption and rain continues, causing massive quantities of plants to die and fall into the rivers, washing out to sea, causing, in turn, a great plummeting in levels of oxygen. By 610 years into the extinction, there is much talk of going to the relatively stable world of Mars, as Earth appears to be turning uninhabitable.

Animals that might have evolved into ATL "people" or been used for food or as beasts-of-burden

Large animals included gorgonopsians and dicynodonts, including the major large animal that survived the OTL extinction, lystrosaurs.

Seafood included (possibly) mollusks, brachiopods, ammonites, trilobites, cephalopods, and various other critters.

Vegetation included (in what is now South China in OTL) swampy plants such as lepidodendron trees that lived in swamp forests and (elsewhere) plenty of conifers, ginkgo trees, and cycads (cycads probably occurring in tropical and other warm areas, which may have been practically everywhere in the warmer parts of the extinction period).

Flowers did not yet exist in OTL; however, scientists in this alternative timeline have managed to produce them through tinkering with genetics. However, they are still rare and highly prized. Colorful palm-like plants and tree-like plants provide the color, and farms don't look very grassy: grass has yet to evolve in the Permian. Short plants with leaves and fruit-like parts and nutty/grainy parts are grown instead.
