Matters are quickly spiraling out of control for humanity and the Systems Alliance. The geth have assaulted a major human colony on Eden Prime, killing hundreds of peaceful inhabitants.
Worse, it seems that a turian Spectre named Saren is working alongside the vile synthetic race, perhaps in an effort to wipe humanity from existence.
The Council must take action against Saren and the geth, but convincing them to do so will not be easy.
Humanity has yet to become a part of the galactic Council, and therefore has little sway over such political matters.
Seeing no other alternative, Captain Anderson orders the Normandy into dock at Citadel Station, intent on meeting with the human emissary to the Council, Ambassador Udina.
Perhaps a united front between Shepard, the captain, and the human ambassador will be enough to convince the Council to intervene on the Alliance’s behalf.

The Citadel
A colossal, multilevel space station located in the heart of the dense Serpent Nebula, the Citadel has existed since time immemorial.
Nobody knows when the Citadel was constructed. Most believe the Protheans built it at the height of their empire, though some believe it was created even earlier.
In the 50,000 years since the Prothean extinction, numerous interstellar species have come to call the Citadel home. It is the political, cultural, and financial capital of the greater galactic community.
To represent their interests, most advanced spacefaring species maintain embassies on the Presidium, the Citadel’s inner ring.
Extending out from the Presidium are five arms known as wards, vast cosmopolitan cities populated by millions of inhabitants from across the galaxy.
The Citadel is built from the same material as the mass relays, making it virtually indestructible. If attacked, the station can close up its arms to form an impregnable shell, protecting all on board.
With a surrounding nebula cloud and a massive fleet as additional defenses, the Citadel is all but unassailable by hostile fleets.
