A timeline from the the launch of the Zenith and Nadir from Terra, through the Firstcome settlers, the Portal Wars and following dark ages, to the arrival of the Zenith and the birth of the modern era.
The portals are discovered in systems close to Terra. The First Horizon’s most promising worlds are colonized. The Second Horizon is explored.
The Empire consolidates its power in the First Horizon. The mystics later known as the Symmetry start to colonize the Second Horizon.
The Empire’s stranglehold on the First Horizon is tightened further to suppress rebellious tendencies. The Third Horizon is colonized with the Empire’s blessing.
The First Horizon lays claim to the Second Horizon. War breaks out. The Empire’s initial fortunes soon turn.
The war between the First and Second Horizon is costly and bloody, and it also gives hope to anti-imperialist forces in the First Horizon. Massive rebellions erupt, but are soon crushed.
An organized rebel movement is founded in the First Horizon. The rebels are accused of being the Second Horizon’s lackeys. The Emperor’s loyalists turn to the Dark between the Stars in hopes of reaching a final victory against the Second Horizon.
The Empire infiltrates the Third Horizon and the Nazareem’s Sacrifice become important allies in the Emperor’s attempts to conquer the Horizon without bloodshed. The Emperor cannot afford another war, not even against the much weaker Third Horizon.
Several of the old factions in the Third Horizon become suspicious of the actions of the Nazareem, but their infighting prevents them from uniting against the First Horizon’s agents.
The First Horizon’s fleets enter the Third Horizon. The Portal Wars begin. The old factions are primarily fighting the Empire, but also each other in confusing side conflicts. Many portals are damaged by the unchecked use of thermonuclear and antimatter-based weapon systems.
Faced with the imminent threat of a full-scale invasion by the First Horizon, a plan is set in motion to isolate the Third Horizon. The few portals that link the First and Third Horizon become targets and are destroyed.
An age of darkness, isolation, and decay. The Portal Wars left in its wake remnants of once great armadas, rifts in the fabric of spacetime, and cities, whole planets even, scorched and destroyed.
After the enemies’ escape route has been cut off, the last of the imperial fleet is caught in the Odacon system and annihilated in the most devastating battle of the whole war.
The Zenith finally arrives at the Dabaran system, but it is already occupied so they choose the Kua system
The fleets of the Legion and the Zenithian Hegemony engage in combat in the Hamura system with none of the combatants gaining the upper hand.
The Legion and the Consortium form a defense pact.
The Legion and the Zenithian Hegemony signs a treaty to form a non-aggression pact.
The Free League faction is founded as a partner to the Consortium.
All other factions are invited to send representatives to the Council of Factions.
The main trade routes through the Horizon are secured by the Legion. The Governor of Coriolis (Absina Lekteli) signs the Free Trader Treaty that gives anyone the right to use the star portals and forbids any one group from seizing control of a portal.
The Order of the Pariah blocks the portals in their home system Zalos, but after being pressured by the other Council members, they back down and ships are allowed to pass, but are heavily escorted.
The Order of the Pariah opens the Samaritan Medical Academy on Coriolis, as well as launching a poverty relief program and a sanatorium for the hyper sick adjacent to the school.
There are riots in the streets, started by unpatriotic groups backed by anti-republican interests. The Guard restores order, but is unable to arrest the real instigators.
In CC60, in the segment of the Traveler, the ghosts from Xene are discovered, and the Foundation makes the first formal contact with the specters from the depths of the gas giant.
During the Cyclade celebrations, the Bulletin transmits a special broadcast from the Foundation's research station at Xene, where one of the five mysterious Emissaries has declared itself the Judge incarnate.
Soon after the arrival of the Emissaries, individuals all across the Third Horizon began manifesting supernatural powers leading to persecution and religious hatred. Many of these so-called "new mystics" travel to Coriolis for protection, and to be closer to the Messenger Emissary, or to the Foundation's Xene station to meet the Judge Emissary.
On the first day of CC61, another Emissary from Xene arrives at Coriolis escorted by two Legion battleships. The Governor of Coriolis makes a statement welcoming the Emissary to the Council of Factions, and it soon becomes known as the Messenger Emissary.
Contact with the colonies in the Taoan system is lost and the Consortium, the Colonial Agency, and the Foundation organize a rescue mission.
