1) EDI found a way to pilot Iokath to the Milky Way while cloaking it from the rest of the Rayath galaxy. The Council races used Iokath as a factory to mass produce ships that will replace all the ones they lost during the Reaper invasion and Sovereign's attack on the Citadel, any droids produced were used as security or menial labor. These new ships are the new Eternal Fleet only 20% less effective than the original.

2) The Council races used Iokath as a factory to mass produce ships that will replace all the ones they lost during the Reaper invasion and Sovereign's attack on the Citadel, any droids produced were used as security or menial labor. Also, with the help of the Jedi, they were able to make Star Forges that are run on light side force energy.

3) Dooku redubs his Sith Empire as the Galactic Empire and issues 3 mandates: (1) All remaining jedi are to be hunted down and executed. (2) Any and all children who are force-sensitive will be taken to be trained as Inquisitors. (3) If the Milky Way hides any of the Empire's criminals, it will be considered an act of war.

4) Alliance scientist, Dr. Catherine Halsey began her own super-soldier project, the SPARTAN Program, but due to the high mortality rate, the Alliance decommissioned the project with only 4 known successes. John-117(Master Chief), Kelly-087, Frederic-104, and Linda-058. These four S Spartans became the Blue Team and went on to serve under Captain Ashley Williams. Master Chief becomes the 3rd human spectre.

5) Leia Skywalker with the help of Galen Marek and Bail Organa create a rebellion and begin the Galactic Civil War.

6) Out of the many Rayath Clone Wars refugees that went to the Milky Way, some were jedi who survived the purge or on the Empire's wanted list. Both the Citadel races and the Terminus Systems would help them "get lost" in exchange that they fight for them at a later date.

7) Thrawn is found by the Empire, becomes a loyal member, and rises to the rank of grand admiral. Wants to unite the Rayath Galaxy under imperial rule to fight the far outsiders and wants to conquer the Milky Way for its resources and for more soldiers to throw at the far outsiders.

8) With the help of former Republic scientists, the Salarians are able to use adegan crystals and create an artificial isotope-5 to power-up all Milky Way ships and their new eternal fleet.

9) Aria T'Loak was in a shadow war with the Hutt Cartel that lasted 10 years and is now in an uneasy ceasefire.

10) Some idiot, low-life thug with delusions of grandeur tried to kidnap and enslave the Normandy crew's children to build a name for himself, but was thwarted and killed by HK-75.

11) The Milky Way galaxy received various flora from Onderon which they then used to help terraform seed life onto barren wasteland planets.

12) The surviving clones that fled to the Milky Way with the other refugees were treated like soldiers, heroes, refugees, and people unlike in their home galaxy where they were seen at best as droids made of flesh. The clones have been aiding the Milky Way by training its forces to fight Dooku's improved army due to the fact that they had first hand experience fighting them. A number of clones went on to have lives outside of the military and even started their own families. The salarians had to make their own chips that were injected into the body to tell each individual clone apart.

13) Emperor Dooku has found a way to resurrect both Darth Nihilus and Darth Malak and has made them his personal, loyal enforcers. He even went as far as to use the force walk ability on Abeloth, further increasing Dooku's power in the dark side of the force.

14) Anakin is unlocking his full potential as the chosen one and like Revan has mastered both the light and dark side of the force, the only difference being that Anakin is vastly more powerful than Revan and has changed his name to Vader. Vader went on to force walk with a dozen long-forgotten jedi and sith, making Vader even more powerful.

15) Liara and Javik uncovered the Protheans’ lost experiments that were used to make all Asari genetically biotic and gave their findings to Alliance scientists so they could alter them to genetically alter the other Milky Way races to be biotic.

16) Because the force bled into the Milky Way through the portal, it was able to spread across the entire universe, but due to the fact that the force spread itself thin in conjunction with being in contact with the dark energy killing suns in the Milky Way, the force was forever changed.
