Mass Effect: Dawn of Tomorrow (IC)
Two hundred years ago, the galaxy was united against a singular, terrifying threat: the Reapers. Every species came together, gathered in the Sol system, and waged war on the bulk of the Reaper forces. One woman, a human named Shepard, led the assault, all the way to where it ended: on the Citadel. Precisely what occurred there, no one knows. But, in the end, something happened. The Crucible connected to the Citadel, a massive burst of red energy exploded from the Citadel, and every Reaper and their indoctrinated forces was destroyed by the energy wave as it coursed over every planet in the galaxy.
As a result of the power of the energy, the Citadel was utterly destroyed, and every mass relay was severely damaged. Moments before the detonation, the galactic forces withdrew from Earth. After the relays were ruined, the humans were once again alone. They scoured their solar system and all nearby planets for the rare, necessary element zero to rebuild the Sol relay. It took them until now to complete it.
Finally, four days after the completion of the Sol relay, it was activated for the first time in almost two centuries. In the Serpent Nebula of the Widow cluster, a mass effect field arrived and discharged around the nearby rebuilt Citadel relay - and the new Citadel. Emerging from the mass effect envelope were a small group of ships, all of them transmitting an old, familiar signal. The Human Systems Alliance, spearheaded by the SSV NR-7 Normandy.
As the ships appeared in Citadel space, C-Sec immediately began running checks on them. Word spread fast across the Citadel about the return of the humans. Some speculated that it was a trap set by bold - and perhaps stupid - pirates. Others believed it was truly the human Alliance. To be safe, the Citadel dispatched one of their most effective Spectre agents: Velia Si'ona.
The MRS Amitia was significantly smaller than any of the human ships, but featured decent enough firepower and exceptional maneuverability to survive them. Velia received the same transponder codes that the Citadel had. So far, they checked out. She opened her communication line to the lead ship.
"SSV Normandy," she spoke, "I am Velia Si'ona, Spectre of the Citadel. If your captain would permit it, I request to board and welcome you back to the rest of the galaxy."
