| >1,000,000 BCE | The Ancients rule the galaxy. All that they ultimately leave behind are pyramid-like ruins, several advanced artifacts, strange lumps of material called Endurium, and a gigantic star-flaring weapon called the Crystal Planet. |
| ca.1,000,000 BCE | The Leghk and Dweenle inhabit the Delta Sector. The Uhl arrives and begins taking control of the Leghk. Billions die in a civil war which ends with all free Leghk being killed or corrupted.
During the war, the remaining free Leghk open the Anomaly into the future so that they may escape the Uhl. The Uhl's Leghk capture the Anomaly and the Uhl sends its offspring through. The free Leghk have no choice but to trigger six supernovae in an attempt to destroy the Uhl. Their ploy fails, but the Cloud Nebula is formed. The remaining free Leghk commit suicide. |
| 35,358 BCE | The Uhl, along with the Uhlek, flee the Delta Sector in an attempt to evade a wave of flaring suns. |

| 3000 | First Wave begins. Numlox and Phlegmak invaders attack the Empire. Spemin beg for Imperial protection and it is granted. |
| 3120 | Veloxi Pact of 3120 is signed. Veloxi and Empire ally. |
| 3190 | Interplanetary Treaty is signed. The treaty guarantees the right of free passage to all neutral species. |
| 3210 | Trans-sentient-inviolate-region Treaty is signed largely in response to the destruction caused by the Phlegmak and their Black Eggs. The treaty guarantees the right of any sapient race to heavily guard any worlds in their possession and to deny landing rights to any species for any reason, with deadly force if necessary. |
| 3225 | Akteron Treaty is signed. The treaty forbids the passage of any vessel of Thrynn registry into territory held by the Elowan, and vice-versa. While honored by the Elowan, in later years the treaty is largely ignored by the Thrynn. |
| 3260 | First Wave ends. Numlox and Phlegmak are believed to be destroyed. Spemin betray Empire again. |

| 3450 | Project Noah is initiated by the Institute in an attempt to preserve a fragment of the Empire from the oncoming hordes. A similar colonization effort is initiated by the Elowan. Both projects ultimately meet with limited success. |
| ca. 3450 | Noah One launches. The expedition ultimately fails due to a malfunction in the transport vessel's Ring Device. |
| 3454 | Noah Two launches. The expedition is attacked by Gazurtoid near the Staff and survives only through accidental passage through a flux. The expedition ultimately makes it to their destination (α125x100, p3) and establishes the colony of Arth. |
| 3466 | Noah Six launches in an attempt to establish a colony world far coreward, past the invading hordes. Noah Six will travel farther away from Earth than any of the other known Noah missions. |
| 3479 | The Noah Nine expedition commences with the launch of the Mechan Nine towards the Heaven colony. Noah Nine is ultimately the last of the scheduled Noah missions to successfully launch. |
| 3480 | Laytonites bomb the colonial transport Lasthope carrying the Noah Nine expedition, forcing the expedition to crash land at α175x94,p1. Lacking sufficient supplies due to their landing, all of the colonists eventually die.
Sol undergoes a catastrophic solar flare, delivering a coup de grace to the already failing Empire. The Empire is destroyed. |
| ca. 3480 | Without the influence of the late Empire to moderate their actions, the Thrynn eventually begin a new wave of fiercer attacks against the Elowan. Ultimately, the Elowan are driven off of their world and out of the system, resettling coreward on new homeworlds, including eventually Elan. |
| 3505 | Bomb hits Arth, creating the Southern Hot Zone. Underground colonists are forced to the surface. |

| 3939 | Lowar discover Shyneum planet. Gorzek discovered on asteroid and given to the Tandelou. |
| 4189 | The Anomaly appears in the Delta Sector. The Uhl's offspring passes through and seizes control of the Umanu. They attack the Lowar.
Lowar establish research base on planet Elthesh (δ84x176, p4) in ongoing effort to procure Leghkian technology. |
| 4239 | The Lowarian vessel Elthar-Esh passes through the Anomaly and retrieves Leghk technology from the free Leghk. Elthar-Esh barely makes it past the Uhl's Leghk and back through the Anomaly, but runs out of fuel before it can return the advanced technology to the Lowarian people. The failure of the mission condemns the Lowar. The Lowar are exterminated by the Umanu. |
| 4400 | Industrial revolution on Arth. A new council is established, forming a single, worldwide government. |
| 4500 | Sublight technology is rediscovered. |
| 4594 | Discovery of the Noah 2 and Endurium in a series caverns on Arth. |
| 4595 | Terrence Wilwater, a well-known philanthropist, assumes the position of CEO of the fledgling corporate conglomerate known as Interstel. |
| 4600 | Construction commences on Starport Central in Arth orbit. |
| 4615 | Interstel dispatches its first superphotonic fleet. Thirteen Hyperion-class transports leave, each with enough fuel for a one year voyage. |
| 4617 | ISS Hyperion returns from Thrynn space with coordinates of Endurium-rich worlds. |
| 4619 | A second ship from the first fleet returns to Starport Central twenty minutes before Interstel Vice-Director Phexipotex is scheduled to give a pre-launch briefing to members of Interstel's second fleet. No other vessels from the first fleet return and are presumed lost. |
| 4620 (SF1) | The second fleet launches days before Arth's sun begins to enter pre-flare stages. Evacuation of Arthlings to other worlds begins; first Arth colonies created. Arth makes first contact with Elowan, Gazurtoid, Mechans, Spemin, Thrynn, Uhlek, and Veloxi.
Thrynn attempt to trick Interstel into destroying Elan.
Uhlek Brain World is destroyed. Uhlek disappear.
Cause of flares is traced to Crystal Planet. The Crystal Planet is destroyed in a daring mission. Discovery of Commander McConnell's log reveals that the Ancients are Endurium.
Rediscovery of Earth. It meets colonization parameters.
Launch of ISS Intrepid, the first ship of her class. |
| 4621 | Endurium ban is enacted by the New Council, which is ultimately adopted by many of the Alpha Sector's extant starfaring races. The ban stymies Interstel's exploration and colonization programs. |
| 4622 | Several species which originated on Earth are imported and reintroduced into the recovering ecosystem. |
| 4625 | The final Hyperion-class transport, ISS Eos, is decommissioned and stricken from Interstel's naval register. |
| 4634 | Spemin discover the flux to the Delta Sector, as well as the fuel Shyneum. |
| 4636 | Spemin stumble across the Elthar-Esh derelict and acquire Leghk technology. Spemin disrupt Delta Sector trade and threaten Arth with invasion.
Spemin steal the Most Valuable Thing from the Tandelou. The Eshvara and Eshvey factions blame each other for the theft; start of the Tandelou civil war.
Interstel learns the location of the Alpha-Delta inter-sector flux. |
| 4637 | Construction of Starport Outpost One begins in orbit of Ptera (δ35x73, p1). |

| 4640 (SF2) | Interstel retrieves the Most Valuable Thing from G'Aeresch and returns it to the Tandelou. The civil war ends.
Interstel obtains Leghk technology via the Anomaly. Discovery that the Uhlek were the Leghk.
Interstel defeats the Uhl's offspring; frees the Umanu. Discovery that the Umanu are Noah 6. |
| 4641 | Widespread Shyneum distribution throughout the Alpha and Delta Sectors commences. Creation of Arth Union of Worlds. In the Delta Sector, the value of the Shyneum Penny (SP) plummets as a result. To avoid a Sector-wide depression, the Arth Monetary Unit (MU) is adopted as the de facto principle currency in the Delta Sector.
Spemin attempt at invasion of Arth meets with spectacular failure. Their defeat causes them to lose control over the Alpha-Delta inter-sector flux, most of their Delta Sector holdings, and a substantial chunk of their native sphere of influence. |
| 4642 | Several Interstel captains report a substantial increase in encounters with Minstrels, as well as a change in the song they had been singing since the species was initially encountered. The new song is reported to be rather ominous.
Initial reports are received regarding apparent expansion of the Gazurtoid sphere of influence. |
