Timeline

PRE-HISTORY
In a distant galaxy, a race of humans called the Altera experience a fundamental split in cultural governance. The majority push for a religious focus, while a smaller group push for a scientific one. Fearing extreme persecution, the small Alteran group choose against using technology which could brainwash their brothers and depart in a ship for a galaxy to call their own. The scientific Alterans will henceforth be known as Ancients.

The Ancient Amelius begins to develop Stargate technology.

The Ancients come upon the Local Group and make the Milky Way their home. They seed numerous worlds with Stargates as well as human life, and settle on a planet they name Terra.

The religious-based Alterans will eventually ascend and be known as the Ori, establishing the Origin religion and creating planets full of worshipers to feed their need for energy.

3-50 MILLION YEARS AGO
The Ancients form an alliance with three other races in the galaxy including the Asgard, Nox and Furlings. They establish a meeting planet on Heliopolis as a form of galactic United Nations.

Proclarush Taonas is abandoned by the Ancients.

A terrible plague cripples the peoples of the Milky Way.

The Ancients of P4X-639 engineer a time machine to go back before the plague to reverse it, but discover the flawed technology only goes backwards by 10 hours. They eventually deactivate the device and accept their fate.

The Ancients create a device on Dakara to repair the damage caused by the plague.

The Ancients of Earth abandon their interests in the Milky Way and set course for the nearby Pegasus Galaxy in Atlantis. Ayiana, a carrier of the plague, is left behind.

The Dakara device activates to relaunch the Milky Way's evolution process.

The Ancients arrive in the Pegasus Galaxy. As before, they create a network of Stargates and seed life on numerous planets. Atlantis makes its home on Lantea.

The Ancients establish a network of defence satellites in the Lantean system.

The Ancients forfeit the 100-year war. They recall their forces to Atlantis for a final stand and create a window for Ancient refugees to return. Numerous ships reach the Lantean system but are destroyed.

John Sheppard, Radek Zelenka and Elizabeth Weir, having narrowly escaped a catastrophic power failure in a future Atlantis, unwittingly trigger a time jump in a Puddle Jumper to this time period. After a fatal crash, Weir is the only survivor, recovered by the Ancients.

Having lost the war with the Wraith, the Ancients sink Atlantis deep beneath the Lantean oceans. Janus, the inventor of the time-traveling Puddle Jumper, disobeys the orders of the council and leaves Elizabeth Weir in the city. She slumbers for 10,000 years, waking at intervals to regulate the power systems so that she may avert Atlantis's future power failure.

Realizing they have missed the evacuation of Atlantis, the crew of the Ancient warship Tria set a course for the Milky Way at light speed.

The Lantean survivors, now on Earth, attempt to avoid influencing the primitive tribes of man. Moros, Ganos Lal and numerous other Ancients seclude themselves and learn to ascend while the rest die out.
