The earliest known records of the Selaiki are from Bronze Age Indus Civilizations (3300 BCE to 1300 BCE) in modern Pakistan.
How the Selaiki evolved from humans is under examination. Based on these depictions, it's believed that the Selaiki had a peaceful, possibly religious, relationship with the local population.
Following the collapse of the collaps of the Bronze Age, Selaikic civilizations emerged mainly in Central Asia.
Selaiki expanded into the near east and africa with the arival of the Median and later Persian Empires. These empires established trade and political alliances with the Selaikic states in the region, eventually incorporating them into the Persian empire under Cyrus, accelerating Selaikic migration across the Achaemenid Empire and even further.
After Alexander the Great's conquest of Persia, it was in the region of Bactria (northern Afghanistan) that Alexander married his first wife, a Seleucid princess named Roxana.
Following Alexander's death (332 BC), the lands he had conquered were fragmented into multiple empires with many having a Seleucid presence. Some of them would be ruled by Selaikic dynasties, and minor Selaikic states would rise and fall.
In the 7th century CE, the largest Selaikic state was established following the Arab conquest (651 CE). The far eastern remnants of the Sassanid empire, whose rulers were under the rule of Selaikic governance, seceded from the collapsing empire to form the Khorasan Empire (654-1220 CE). This period marked a golden age in medieval Selaikic history, as trade and people from all over the known world passed through the empire, bringing considerable wealth to the elite. Selaikic scholars led the world in fields such as mathematics, astronomy, politics, and engineering.
In 1220 CE, the Mongols invaded the Khorasan Empire, brutally conquering the land. Legend has it that they toppled the statue of Maximus in Selga, and the collapse was so violent that it caused a miniature earthquake in the city.
During the last four centuries, the Selaiki continued to live as a minority in other parts of the world, at times establishing petty kingdoms. However, they never regained the same influence they had after the destruction of Khorasan.
It is speculated as to how the Selaiki went extinct, but several factors could have contributed to their decline. The Mongol Invasion, the decline of the Silk Road, the onset of the mini-ice age, the black death, and the discovery of gunpowder are all potential factors to consider.
