Timeline of Stargate Events

[Jason Conway]

Stargate: Meropis Timeline
This thread will be updated regularly, whenever our expedition finds some new information/episodes are completed.
Events in bold are events to do with Meropis.

Roughly 50 Million Years BC
* The Alterans (now known as the ancients) evolve in a distant galaxy and progress to a scientific level far beyond that of present-day humanity.
* An ideological split appears between two factions of the Alterans: one progresses toward an increased belief in religion and becomes known as the Ori, the other toward belief in science. The Alterans which believe in science come to the Milky Way and settle on Earth.
* They seed a network of Stargates throughout the galaxy and colonize many planets, the oldest of which, the Antarctic Stargate, was planted on Earth 50 million years ago.

5-10 Million Years BC
* The Alterans within the Milky Way suffer from a devastating plague, possibly of Ori origin. Many try to Ascend to escape. Atlantis, the Alterans capital city within the Milky Way, departs for the Pegasus Galaxy via its star drive. Some speculate that they were fleeing from the plague.
* A small group of Alterans flee through freshly seeded Stargates to the Triangulum Galaxy where they begin, in secret, to build an experimental copy of Atlantis named Meropis. Speculation says that parts of Meropis were trial runs for Atlantis upgrades.
* An Alteran named Aiyana is left behind for unknown reasons, and ends up frozen in ice.
* After the city leaves, the Alterans activate the Dakara Superweapon/Alteran Ship to try and reseed life in the galaxy after the plague.
* In this period of time, the Alterans launched the automated ships to seed the first known design of Stargates throughout many galaxies, with another ship called "Destiny" planned to follow it up and explore those planets.

Between 5-10 million and 8000 BC
* The Alterans settle within the Pegasus galaxy, colonizing several worlds and instigating the evolution of humanity on others. Their people come to be known as the Lanteans. The Lanteans encounter the Iratus bug in the Pegasus Galaxy and, possibly by feeding on humanity, the bug acquires human DNA, evolving into the humanoid species, the Wraith. In their desperate search for better weapons against the Wraith, the Lanteans create nanites to infiltrate and kill living beings. This has unintended consequences, however, when the nanites evolve, eventually into the humanoid Asuran. Seeing that their experiment has gotten out of hand, they attempt to destroy all traces of it, but fail.
* In the Milky Way galaxy, the Goa'uld and Unas evolve on P3X-888.
* The "second evolution" of humanity evolves on Earth.
* The Ascended within the Milky Way shield the galaxy from the Ori.
* The Asgard in the galaxy of Ida begin exploring space within and outside their galaxy.
* The war between the Wraith and the Lanteans in the Pegasus galaxy escalates to the point where Atlantis is constantly under siege.
* Being guided by their Milky Way brethren, the Alterans left living in the Triangulum Galaxy begin to ascend. Those that remain are attacked by an unknown race of creatures, they are unable to defend themselves with such a small population and flee via the Stargate to Atlantis. Meropis, in a start of disrepair and half-completed works, is shut down and abandoned. An "invisibility" cloak is placed over it to prevent unwanted detection.
* The Lantean people and the Triangulum Alterans decide to leave Atlantis for Earth by going through the Stargate. Atlantis, protected by a powerful force-shield, is submerged to the bottom of the ocean.
* The Lanteans leave Atlantis to find that the native peoples on Earth were quite primitive, preventing them from ever rebuilding their great civilization, so the Lanteans lived out the rest of their lives with the native peoples in peace.

8,000 BC
* The Ancients on Earth go on to influence the language and mythology of Ancient Rome, Celtic legends, the myths of Greece, and their research on ascension forms the basis of Buddhism.
* Many Ancients continue to use the Stargate network, and form an Alliance of Four Great Races, with the Nox, the Asgard and the Furlings, who had become very advanced. This Alliance lasts for centuries.
* The Goa'uld discover Earth and Humans, and abandon Unas as hosts. They take dominion over many areas of Earth, particularly Egypt, and pose as Gods.

Between 8,000 & 3,000 BC
* Humans become slaves and worship the Goa'uld. In Egypt, the theocracy founds Egyptian mythology.
* Ra becomes the Supreme System Lord and the only Goa'uld ruling Earth.
* The last remaining Ancients either die out or Ascend.
* Omoroca arrives on Earth and attempts to prevent the Goa'uld from securing domination over Humanity. The Goa'uld Belus kills Omoroca, though it has been theorized that her influence led to the eventual Human rebellion.

3,000 BC
* The Humans of Earth rebel against the Goa'uld Ra, possibly instigated by the Oannes, and free themselves of his domination. The Stargate on Earth is buried and Human civilization begins its natural evolution.

Around 1,000 AD
* The Ancient Moros, later known as Merlin de-ascends on earth, where he begins building a weapon to neutralize ascended beings, the Sangraal. He befriends a group of knights and creates the basis for the Arthurian legends. An ascended ancient, Morgan Le Fay, destroys the weapon but places Merlin in stasis, so that he may re-build it if the Ori ever threaten the Milky Way.

Jack O'Neill was given command of SG-1, with Samantha Carter as his second-in-command and Dr. Daniel Jackson accompanying him.
* While exploring the planet Chulak, SG-1 are captured and imprisoned. Jack O'Neill however, convinced Apophis’ first prime Teal'c to help them escape and return to Earth.

* The Meropis Expedition arrives in the Triangulum Galaxy after a five-week hyper drive journey. They discover Meropis vacant and cloaked, upon discovering the entrance they accidentally trigger some security fail safes causing several expedition members to fall ill. Dr. Goodwin is able to administer a cure in time.

June 2010
* Atlantis is forced by the IOA to relocate to the moon, but in doing so and re-calibrating the Stargate, they trigger an ancient fail safe that seems impossible to turn off.

* Homeworld Command looses contact with the crew of the Destiny. Next of kin are informed.
* Meropis is again attacked by three Etruscan vessels who manage to destroy the shields and subsequently one third of the city.

With the firepower from Atlantis two ships are destroyed and one flees, thus winning the battle of Meropis for the foreseeable future.

The Vanir announce they are building a weapon to tip the balance in the war with the Etruscans.
* General O' Neill announces his retirement.
* An alien named Dorane awakens from stasis in a chamber below Meropis. He leads an army of Koan, which are later revealed to be mutated versions of a gentle native species, to attack the city.

McManus escapes after stating there is a Lucian Alliance spy on Meropis. Dorane and Lt. Hopper are presumed dead after piloting a Puddle Jumper off-world with a live bomb aboard.

December 2010
* Dr. Rodney McKay visits Meropis. A storm containing temporal radiation surges around the city, causing the base to suffer visions of the past and possible futures.

Doctors McKay and Glavish are able to modify the shields to the modern day human DNA blueprint to allow the city to protect itself and them from the unique weather event.
* Discussions begin at Homeworld Command around a gradual worldwide exposure of the Stargate program following several small but significant information leaks in the media.

* An assassination attempt is made on General Conway by a brainwashed Lucian Alliance spy. At first this is successful after an explosion destroy's his office and part of the central spire, but thanks to Dr. Clark and SM-1 using an experimental ancient device to time travel, the event is actually prevented from ever happening and the culprit is arrested.
