Template:Lantean Era

Lantean Foundation
Though only those Ancients who fled the Milky Way survive the Reaper culling of their galaxy, some merely were using it to hide their eventual return. One group of Ancients, abroad their City Ship Atlantis, waited until the Reapers had again returned to Dark Space and settled on a planet named Lantea in 780,000 B.C.E., founding the Lantean Empire and came to be known as the Lanteans. Finding the galaxy now devoid of space-faring life and knowing of the eventual return of the Reapers, the Lanteans seeded the galaxy with baseline Humans, who would come to call them the Ancestors.

It was the Lantean's intention to develop their society along more controversial lines then their predecessors, the Lanteans would become the technological and strategic leaders, whereas the baseline Humans they had seeded would be their industrial and military support. Attempts by the primitive Asgard, Goa'uld, Nox and Furlings to contact the Lanteans were rebuffed, more so because of the Lanteans feared the Reapers would cull them too if they knew what fate they faced.

Lantean-Reaper W​ar
The buildup of the Lantean Empire did not go unknown to the Reapers who were summoned a mere ten-thousand years after they culled the Ancients.

From the estimated start somewhere in 787,000 B.C.E. and for over one hundred years, the Lanteans and the Reapers warred with each other. At first, the Reapers were at a severe disadvantage: the crystalline technology of the Lanteans was far superior to the organic technology of the Reapers, and one Lantean warship was able to incur massive damage on several Reaper capital ships at once with their devastating drone weapons while at the same time suffering little to no damage themselves due to their powerful shield technology. The Lanteans, careless and overconfident, began to send their seemingly invincible warships deeper and deeper into Reapers-controlled territory. After a long period of time and with great cost to themselves, the Reapers managed to capture a number of these vessels and obtain the Zero Point Modules powering them. Using these incredible power sources, the Reapers created at least one cloning facility, which they used to rapidly increase numbers of indoctrinated slaves and give them a much needed advantage via swarm tactics.

The tide of war quickly turned in their favor; it no longer mattered that the Lanteans would win almost every battle: the Reaper indoctrinated slaves kept coming in floods.

Now finding themselves in a war of attrition, the Lanteans slowly fell back as the Reapers absorbed Lantean territory into their own, willingly facing the mighty weapons platforms and outposts protecting Lantean-controlled space in their effort to destroy their greatest enemy. Desperate, the Lanteans began to take more drastic measures, turning to their advanced technology to help them regain an advantage. Project Arcturus, an attempt to extract Zero point energy from our own universe, and the Asurans, nanites designed to destroy the Reapers on a cellular level, were two such attempts. They both failed, with disastrous and far reaching consequences. The closest the Lanteans ever came to developing a means of defeating the Reapers was the Attero Device, which could destroy Reapers ships in attempting to enter or leave FTL, but its devastating and unforeseen side-effect of cause a Mass Relay to be destroyed by its own Element Zero core, resulting in literally a thousand Reaper and Lantean-held systems to literally self-destruct in a matter of days. This led to it being abandoned. By the time the Attero device was conceived and subsequently shut down, it was obvious even to the Lanteans that they were losing the war.

They continued to gradually lose their ground against the Reapers for several years until the Lantean-system was all that remained of their domain. In a final attempt at ending the war, the Lanteans sent a delegation to meet with the Reapers and negotiate a truce. The Lantean delegation was protected by some of their most powerful warships, but they were ambushed by the Reapers's massive fleet. Their last chance at peace now gone, it was only inevitable that the Lanteans would eventually face their defeat.

Siege of Atlantis
While the Reapers were at first unable to reach Atlantis due to the numerous weapons platforms deployed throughout the star system, they were eventually able to destroy most of them and continue their conquest. Its last line of defense now gone, nothing was left to prevent the Reapers from advancing to Atlantis itself, held off only by the city's powerful shield and its stockpile of drone weapons. Even though the Lanteans were able to destroy the Reapers vessels every time they attacked, the Reapers were relentless and sent more ships to attack time and time again. Hopelessly outnumbered, the city's supply of drones rapidly dwindling, and the shield under continuous bombardment, the Lanteans ultimately decided to sink the city (which would allow the shield to hold for far longer than it ever could on the surface). Atlantis itself was brought to its knees, and the Lanteans had come to realize there was nothing more they could do.

The Lantean Council made the decision to abandon the galaxy to its fate and those that remained would be hidden in a vault deep inside Lantea's crust. Those few hundred were intended to rebuild another Lantean Empire and to attempt to defeat the Reapers a third time.

Lantean ​Twilight
The continued Reaper bombardment of Lantean eventually resulted in mass fallout and ecological damage. To wait for the most survival conditions to return, the Lantean administration AI placed in charge of the Lantean vault had to wait nearly four-thousand years before releasing their charges.

Even at this stage, the Lanteans quickly realized that there was no hope of rebuilding their society, as Lantea was too harsh to support life. Some chose to go to other worlds, others ascended to new levels of existence, and some chose to join the native races, where they integrated into current galactic society.
