Aligned timeline
As is to be expected when multiple authors and writers are working on a continuity, the Aligned timeline bears more than a few discrepancies and continuity hiccups. Nevertheless, we here at the TFwiki have tried to rectify this as best we can.
Before the beginning

Primus and Unicron battle for eons. To try and turn the tide, Primus creates the Thirteen Primes. One Shall Rise, Part 1 Over the course of the fight, Solus Prime, at the urging of Megatronus Prime, creates a great weapon to fight Unicron, although Solus herself worries that this power could corrupt them. The Thirteen vote seven to six to keep the Requiem Blaster and not destroy it. Transformers: Exiles Ultimatley, the Primes temporarily defeat Unicron, and the Chaos Bringer disappears, for the time being. One Shall Rise, Part 1 Unicron disappears for a time. Following the defeat of Unicron, Primus becomes one with the Core of Cybertron, and he gives life to future Transformers through the Well of All Sparks. One Shall Rise, Part 1. Early generations of newborn Transformers must brave the Underworld to reach the surface, which, over the years, becomes a deeply ingrained custom. Transformers: Exodus
Near the beginning of time
Solus Prime is murdered by Megatronus, causing the first schism in the Primes. Megatronus and the Liege Maximo soon seperate from the other Primes, and in the course of this great battle Nexus Prime is forced to fragment himself into five robots, each one carrying and guarding a fragment of the Cyber Caliber. His components were dubbed Clocker, Mainspring, Chaindrive, Cannonspring, and Pinion. The fight has lasting repercusions for the Thirteen- Megatronus and the Liege leave the Primes for good, and the other eleven go their seperate ways, with only Alpha Trion remaining on Cybertron. Transformers: Exodus. Gradually, though, the Thirteen Primes are forgotten, and
The Age of Wrath
The Quintessons invade Cybertron and interfere with the development of the planet's occupants. The aliens modify the bodies of their new servants to serve their own ends, such as installing cockpits on the bodies of the Seekers. This period becomes known as The Age of Wrath. The Age of Wrath comes to an end when the Quintessons are overthrown by Sentinel Zeta Prime, part of the Elite Guard. Under Sentinel's rule, Cybertron entered its Golden Age. Transformers: Exodus
The Golden Age
The Golden Age bring sweeping changes to Cybertronian social structure and hierarchy. As only two Primes now remain on Cybertron, Sentinel Prime takes control of government and ushers in a new era for Cybertronian civilization, by instating the High Council. Under his rule, the space bridge project allows trailblazing Cybertronians to colonize faraway worlds, including Gigantion, Velocitron, Junkion, and the Hub. The construction of the spaceport on the Hydrax Plateau begins, Trypticon Station is put into orbit, and the Moonbases are also constructed. Transformers: Exodus
The first Cybertronian data cylinders are created, which store the accumulated knowledge of Cybertronian society. T.M.I. However, the Golden Age draws to a close as the space bridges begin to fail and other cracks begin to show in Cybertronian civilization. Before long, the space bridge project is abandoned. The Transformers now stranded across the galaxy begin to develop along their own lines, gradually evolving into entirely new breeds of Cybertronian that are well-adapted for life on their new homeworlds. Transformers: Exiles
Caste System Years
The caste system is implemented, where civilian guilds oversee and assign newly created Transformers to jobs, and it eventually becomes a major social institution under the urging of Sentinel. Alpha Trion, however, disagrees with many of these changes, and retreats further and further into the Hall of Records, eventually becoming a recluse. This controversial reorganization does not go unnoticed, though, and many newly born Transformers become dissatisified with their lot in life.

The city-state of Kaon, populated mostly by low-caste miners and workers, soon turns to gladitorial combat as a way to escape from the boredom. Several such underground rings emerge in Kaon and Slaughter City, low caste areas where workers seek a distraction from the drudgery of their lives. The High Council, aware of why the games began, does nothing to stop them. One particularily powerful warrior, an energon miner formerly known as D-16, takes on the name Megatronus, but later shortens it to Megatron.
