This is a AU crossover between Stargate Atlantis and The Silmarillion.

NOTE 1: Some of the races that belong to the Atlantis Galactic Federation (AGF) can be found in Chapter 12 of my story Long Lost Brothers at the bottom of the page. I got lazy and decided not to rewrite it. I also kept the name Atlantis Galactic Federation because the Joint Chiefs on Earth decided to name their Federation after Atlantis. The AGF is in five galaxies: the Milky Way, Pegasus, Andromeda, Ida and Triangulum.

NOTE 2: The humans in the Pegasus galaxy call themselves Lantians.

NOTE 3: Below are the specs for all AGF ships. The unidentified torpedoes are planet destroyers and the Ancient beam weapon has been upgraded throughout the years – thanks to the Aldans.

During their years of exploration in the Pegasus galaxy and after going through the Ancient's database on Atlantis, the Lantian's discovered more stargates to the Andromeda and Triangulum galaxies. They already knew some of the gate addresses to the Ida galaxy, where the Asgards once lived, and they found more in the Ancient database. The Andromeda and Ida galaxies coordinates have eight chevrons and the Triangulum galaxy coordinates have nine chevrons or a ninth gate, the same as the Destiny.

In the Ancient database, the Lantians also found where they could find more Ancient drone weapons, ZPM's, the Ancient beam weapons, stargates, DHD's and other ancient technology - and they will not have to worry about ZPM's and weapons ever again. The AGF found over a thousand stargates and DHD's in the Pegasus galaxy, along with 508 space gates and more stargates in the Milky Way galaxy. They also found where the Ancient databases were on each planet in the Pegasus and Milky Way galaxies and destroyed them so no one could get their hands on that technology.

The Lantians also found a diagram of a Security Net in the Ancient database, that was even better than the Ancient shields, to protect Atlantis, AGF planets, ships and installations; but for whatever reason, they never installed it. The Ancients also made sure that no one could ever reverse engineer that technology. The AGF now uses Ancient shields on all their ships, planets and installations instead of Asgard shields; and if those shields ever went down, the Security Net will be activated.

The founding members of the AGF are Humans (Tau'ri), Jaffa, Galarans and the Aldans, who're from the Andromeda galaxy. The Aldans are experts in robotics, engineering, computer sciences and diplomacy. Unbeknownst to the Aldans, the Ancients kept an eye on them like they did the Asgards and they're just as smart and surpassed both races in some respects and can be ruthless soldiers when the need arises. They're a humanoid race with black spots on their foreheads similar to small boxes that go from the center of their foreheads to their hair lines; much like a head band and their coloring resembles a permanent tan and they have black hair and brown eyes. The Aldans have two habitual planets in their star system, both with stargates, three moons, two gas giants and the name of their home planet is called Aldania.

The Aldans tend to have a lot of children and needed to spread out as they had already colonized the other planet in their star system. The Lantians suggested, after they met them and got to know them, that they colonize a world in the Pegasus galaxy since there were numerous uninhabited planets in that galaxy. The Aldans did so and now have two colony worlds in the Pegasus galaxy. That was over three-hundred years ago and the Aldans are now considered the sixth great race.

Pegasus Galaxy - Unknown Space - 25,000 Years Ago

A ship dropped out of hyperspace and launched a cloaked probe a few light years from the planet and then jumped back into hyperspace. No one on the planet saw the ship arrive or depart; however, as the years went by that probe captured valuable information which will be of great help to the Saviors many years later.
