The first citizens of Cybertron emerge from the Well of Allsparks and each of the Thirteen take a number of them under their wing. Most of the population is nomadic, and congregates around the Primes for safety and guidance. The War of the Thirteen breaks out, and Solus Prime, Megatronus and Liege Maximo die. The rest of the Thirteen drift into conflict with each other, and eventually leave Cybertron or retreat into the Realm of the Primes. The population begans settling down, and forms religious sects based on the teaching of the Thirteen, becoming the original form of Primal polytheism, the Thirteen Sects.
The growing population concentrates into city-states with high amount of travel and traffic. The name "Cybertron" is used, but there's no official conditions of citizenship, only sect membership which itself is also voluntary. This eventually lead to the development of a civil government and the beginning of the Golden Age.
The outworld colonies of Cybertron are attacked by Quintessons and contact to them is lost. The Council of Thirteen, highest body of civil government, begins plans to create a Cybertronian defence force but the Quintesson forces reach Cybertron before they can gain full backing from the sects. Sentinel Prime appointed as high general of Cybertron, and the Council of Thirteen becomes the High Council of Cybertron to direct the war effort. Cybertronian identity emerges, and Primal Church is established as an agreement between sect authorities to validate Sentinel’s authority. The Cybertronian Armed Forces, under Sentinel Prime's command, win their first strategic battles agains the Quintessons.
The Quintesson assaults on Cybertron start to taper off as more of the society is brought under the High Council's control, and mecha are moved into jobs better serving their alt-form function. The increased productivity and higher optimisation of labour led to a surplus of resources that allowed the Cybertronian Armed Forces to gain decisive victory and force a Quintesson retreat from Cybertron. After the official end of the war, the Council began enacting restructuring measures to aid with rebuilding, solidifying new social strata. The former religious sects that had been unified during the war began causing conflict within the Primal Church. In response, the High Council creates the guild system, and uses it to reinforce alt-form based social structures.
At the height of the functionist movement, Megatron of Kaon emerges, joins with Orion Pax to found the Decepticon movement. The bombings of Stanix and Six Lasers over Cybertron occur. The council torpedoes the reform suggestions and drives a wedge between Megatron and Orion Pax after Sentinel’s disappearance. War breaks out in Decepticon controlled regions, classified as an insurgence/terrorism elsewhere. Torus states start seeing border fights and infiltration in Praxus and Tarn. Eventually this leads to open warfare between the Decepticons and the Autobots, led by Orion Pax, now Optimus Prime.
