The Ancients
750,000 to 450,000 B.C. Milky Way Galaxy visited by at least two highly advanced races collectively known as the Ancients. These races are theorized to have engaged in projects of planetary and stellar scope increasing the number of stellar bodies with planets with life sustaining conditions. They are also suspected to have seeded many of the worlds so positioned with pre-sentient life.
450,000 to 200.000 B.C. Height of Ancient civilization. Ancients inhabit much of the galaxy creating multiple artifacts of stellar size. Surviving examples include the Centari Rosettes and the Shaloi—Mintak Stargate.

110,000 B.C. Multiple empires rise and then fall as they grow too large to be managed centrally.

First Empire
94,700 to 50,000 B.C. Massive expansion and consolidation of the empire into noble houses centered on key technologies. Designations of House Major Status are initially assigned to houses that supported House Eximus during the wars. Additional Minor House designations are granted for development of new vital technologies and for exceptional service to the Throne.
50,000 to 20,000 B.C. The empire reaches its largest size and enters its Golden Age. Advancements in technology allow for the majority of the Imperium to pursue academic and cultural endeavors free of the need to provide sustenance or shelter. Development of non-organic sentience provides a workforce that requires only power and repairs to sustain it.
20,000 B.C. Several Minor Houses, dissatisfied with the calcification of the house system (it had been over 6,000 years since the last minor house had been elevated to House Major Status) form the Reformation League. The League begins petitioning the Throne for a review of five key Houses Minor for elevation.
19,950 B.C. After repeated attempts to get the Emperor to review the house system the League begins to grow as more of the minor houses join. The League’s planning begins to move away from reforming the system from within to exploring the possibility of unseating the Emperor and replacing him with a representative government.
19,940 to 19,245 B.C. League grows in support, though it is agreed that unseating the Emperor without first acquiring the secrets of the FTL communications is unworkable the end goal of the League remains the establishment of a representative government.
19,244 B.C. After a failed attempt to seize a ComNet station fails, House Darlen is declared a renegade house and its holding declared forfeit. The nobles of the house flee into uncharted space along with all the house technology they could transport.
18,953 B.C. After increased attempts on Imperial research and manufacturing facilities by the minor houses, the Emperor declares that every minor house will be overseen by a major house in close proximity to their holdings. The League is also ordered to disband and further membership in that body punishable by being declared a renegade house.
18,934 B.C. Using agents within the Imperial scout service the League reclassifies an undeveloped system as having an unstable sun and begins establishing a base of operations beneath its prime habitable world.
18,900 B.C. The League begins building the “Graveyard Fleet” of ships reported as destroyed in battle or dismantled for scrap. Ships are repaired to operation status then mothballed in the oort cloud of Prime Base.
17,255 B.C. The Graveyard Fleet reaches 10,000 ships.
16,964 B.C. Accident by researchers at Prime Base causes one of the system’s gas giants to ignite. Incident is written off by Imperial government as proof of the instability of the star and the stellar classification is raised from hazardous to banned.
16,352 B.C Researcher’s at Prime Base develop the StarKiller device, a weapon capable of inducing a nova-like eruption of a stellar body.
15,990 B.C. Construction begins on a weapon platform capable of powering the StarKiller.
15,850 B.C. StarKiller completed, Graveyard Fleet reaches 100,000 ships. The League gains the support of House Carlion, a major house built on android production. Recruitment of crews for the Fleet begins.
15,545 B.C. A scout vessel belonging to a loyalist merchant house mis-jumps into Prime Base system undetected. After recording the StarKiller in orbit around Prime Base the ship limps back to Imperial space with its discovery. The League begins activation of the Fleet.
15,544 B.C. House Carlion convinces the League that they can capture one of the ComNet hubs intact using a strike force of advanced androids. The League begins its offensive into Imperial space. The Fleet is joined by the combined fleets of the minor houses as it pushes through the Empire towards the Imperial home world of Talosia.
15,540 B.C. The Graveyard Fleet reaches Talosia. As The Imperial Fleet engages the League buying time for the Imperial House to launch the Seed, a vessel designed to carry the Imperial heir and vital house secrets out of the hands of the rebels. Once the Seed is reported clear of the League the Emperor engages his own counterstroke and shuts down the ComNet by ordering all the hubs to self destruct. The League begins the siege of Talosia. The siege lasts 127 days and finishes with the death of Largo Eximus XXXIV.
