The Crucible completed its function, and vaporised every Reaper in existence. As the last was destroyed, all the husks created shut-down and lay dormant. Earth, and every other planet was saved. They were ravaged, but they could be re-built. Billions were killed or converted to husks. Though billions more would live on to reclaim that which was lost.
There were other survivors present on the Citadel, including the Council & Commander Bailey. Who would later take the mantel of the Executor. Most were successfully evacuated due to the size of the fleet assembled and then assigned to protect the evac shuttles.
All but a few of the Relays were destroyed, the massive fleet was stranded in the Sol system. Though through the combined knowledge and efforts of all allied forces, the Relay was eventually re-built and made operational. In the preceding years, the network was eventually restored. Though millions died throughout the galaxy due to cut off supply lines.
Shepard survived his injuries, and later became one of the few enduring names all in the galaxy would remember through the test of time. He married Ashley Williams after recovering, and they later had a family. With no way possible to be a Spectre after the battle of Earth, he was ushered to take a dual role as President of the new Alliance Parliament and the Human councillor on the Citadel. His terms in both roles lasted an unprecedented 14 years, such was his popularity and importance to the other races. He stepped down from both roles when the Sol Relay was confirmed as operational.
While retired, he was called back to help resolve disputes on occasion. He had a lasting and immeasurable impact, which laid the foundations for a galaxy wide united government that bore fruit centuries later.
Admiral Anderson also recovered, he assisted with the initial recovery efforts in the first few years and then retired to start a life with Kahlee Sanders. Anderson saw out most of his life in seclusion, with Kahlee assisting initially with the surviving biotics before doing the same.
The Krogan settled on Mars in the years they were stranded in Sol. Under Urdnot Wrex's leadership, the species bred at its own self-regulated rate. Growth was stimulated, but not to the terminal levels that initiated the rebellions. Their embassy was re-opened, perhaps one day they will join the council.
The Geth/Quarian Alliance brokered remained after the battle of Earth. Technology, colonies and other resources alike were shared between the two species. The animosity the Quarians had towards the Geth declined with each passing year the Alliance endured. With Tali as one of the main spearheads for the continued peace. She remained with the Admiralty board and forged her own path instead of trying to follow her fathers.
Javik did as he pledged to Shepard. He was granted a small ship, complete with status pod and he travelled at convention FTL. His final fate would remain unknown for many years…
Garrus Vakarian remained at the side of his leaders. When the network was restored, he was assigned as leader of the task force to secure the Omega station. Aria was eventually killed on Omega by Garrus's hand, as she refused to follow more Citadel like conventions in the running of the vast station. His actions eventually brought stability to Omega and were the first in a long series of steps to bring lasting peace to most of the Terminus Systems.
Liara T'Soni was one of the key personnel in discovering how to re-build the Mass Relays. She later vanished upon their restoration to resume her role as the Shadow Broker. It is believed she may have had a family. Her security and secrecy was tightened considerably as she tirelessly restored the information network to its former glory. She would carry on that role for another 800 years.
Jack, Kaidan, Jacob & Thane. All killed in action before the Reapers invaded, are just a few of the many heroes that were lost. They will all be remembered…
