-**Tagra** ([[Chaatai|Chaatai]]: "world") is a continent located at the South Pole of its world. Its center is covered by an icecap that grows and shrinks with the seasons, and the rest by belts of tundra and taiga that extend to the sea. A ring of storms and sea currents surround the whole continent, making the surface of the sea effectively impassable. It is peopled by black-feathered intelligent beings who call themselves //[['ikra]]//, and who have built glorious civilizations in the narrow, ever-precarious fringe between ice and seawater.+**Tagra** ([[Chaatai#Language|Chaatai]]: "world") is a continent located at the South Pole of its world.

 In fact, Tagra is Antarctica, as it was 33.6 million years before the time of humans (33.6 mybth), at the very beginning of the [[https://en.wikipedia.org/wiki/Oligocene|Oligocene]] epoch. The greenhouse age of the Eocene, during which tropical rainforests rose up to the Arctic Circle and crocodiles swam over the North Pole, has just ended. For the first time since before the age of dinosaurs, permanent ice covers the poles, and it will only keep growing. The very existence of the //'ikra// may be about to find an end. In fact, Tagra is Antarctica, as it was 33.6 million years before the time of humans (33.6 mybth), at the very beginning of the [[https://en.wikipedia.org/wiki/Oligocene|Oligocene]] epoch.

-  * [[Chaatai Republic]] +According to the historian-philosopher Kyu Taika-Graa'a, there are three natural functions of government, that tend to concentrate into three groups in tension with each other: a Red Order concerned with metaphysics, a White Order concerned with warfare, and a Black Order concerned with economic production. The supremacy of one of these groups upon the others produced the different regimes of Tagra's main powers: in Kru'u, the militaristic White Order rules as the Strategae; in Chaatai, the Black Order takes the form of the Guilds and their Parliament; in Takrakaya, the Red Order is represented by the Divine Empress, acting through the imperial bureaucracy. The different Tayaka and !Akau'a states are not included in her analysis.

 + 
 +The islands Gudju and 'Ai!u'ai have been produced between the late Paleozoic and the early Mesozoic (300-200 mybth) largely by the [[https://en.wikipedia.org/wiki/Subduction|subduction]] of the Pacific plate, much like the Andes, producing elongated mountain ranges with important, and still present, volcanic activity. The rock is mostly volcanic andesite and rhyolite. The region of Kru'u has a similar nature. 
 + 
 +The greater part of Tagra is formed by a vast and very stable Precambrian shield, composed by igneous and metamorphic rocks that formed over 3000 mybth. Limestone, sandstone, and shale have formed thick sedimentary layers over this shield in the Palaeozoic and Mesozoic eras. Significant coal deposits have formed all over the continent during the Carboniferous period (350-300 mybth), when it was located on the Equator and covered with swampy forests. Oil and gas deposits are found around the Sea of Storms. 
 + 
 +Between these two parts of Tagra there is another rift, slowly growing apart, which has produced the Dragon's Jaw. 
 + 
 +Deposits of iron ore have been discovered by human geologists west of the Throat of the Sea. In fact, these are the oxidized remains of Chaatai's industrial cities.

Line 59: Line 86:
 Note how the sum of days of the year is 367, rather than 365: this is because days have somewhat lengthened over Earth's history. 31 Jun and 32 Dec are added to the count. The other numeration (1-367) is based on Chaatai's calendar, which fixes day 1 = 23 Jul, the first sunrise of the year. In all cases, 20 Sep and 22 Mar are the dates of the equinoxes. Note how the sum of days of the year is 367, rather than 365: this is because days have somewhat lengthened over Earth's history. 31 Jun and 32 Dec are added to the count.
