They Shall Not Pass!

by Grubkiller19

Mankind has been through so much in it's struggle for survival. But the Empire has no regard for Man's problems. Only for its own quest for power and domination. The Empire moves to subjugate the only people that has ever dared to defy them. But they will find that to be a difficult endeavor. DISCONTINUED.

1. Chapter 1-timeline

Disclaimer: I do not own anything.

The year is 2561. It has been 8 years since the Human-Covenant War ended, but Humanity's struggle has not ended.

Instead it has only intensified. After Surviving a revolution in the outer colonies that led to both the creation of a collection of rouge colonies known as the Systems Alliance and the Breakdown in First Contact with yet another collection of Alien Species known as the Citadel Council, and war with remnants of the old Covenant that have refused to cease hostilities in 2552, Humanity seemed to be on the brink of Collapse once again.

But Miraculously, they've survived. But not only that, they have managed to become an unchallenged Galactic power in the Orion Arm of the Milky Way.

But some things don't last forever.

Now Humanity has a new threat. This one takes the form of the Galactic Sith Empire from the nearby Andromeda Galaxy, and with almost everyone making Concessions to the Sith as they expand into the Milky way, Humanity seems like the only entity willing to dare look the New order in the eye and say, NO!

Now, the Empire moves in to bring the people of Earth and it's colonies to their knees. But that they will learn that despite having just gotten out of two wars for their survival, Humanity's resolve is a strong as ever. The UEG declares a state of emergency and the UNSC defense force, the military arm of the UEG, steps in to resolve the crisis.

Unbeknownst to the Sith Empire, and all of the galactic powers watching on the sidelines, each UNSC serviceman marches off to the front with these words on their lips: They Shall Not Pass!

March, 2553: Humanity and the Elites sign the peace treaty that officially ends the Human-Covenant War.

Summer, 2553: Humanity comes into contact with the Turian Hierarchy. First Contact breaks down and the Turians invade the UEG outer colony Shanxi, the first planet to both fall to the Citadel races, but also openly rebel against the UEG, which inspires other colonies to secede. This leads to the creation of the Systems Alliance, an anti-UEG organization, which joins the Citadel Races. This leads the other governments of the Citadel Council to intervene Between the UEG and the Turians/SA. The Asari Republics and Salarian Union offers a peaceful solution, in which the Turians and UEG sign a peace treaty, while the Systems Alliance joins the Citadel as an associate race. The UNSC adamantly refuses, seeing the Turians as invaders, and the Systems Alliance as traitors. So they attack.

Fall 2553-Winter 2555: Humanity fights the Citadel Council in a bloody war that sees little movement in the frontline. The UNSC outmatches the Citadel technology and with experience. But the Citadel has greater numbers, and economic/scientific aid from their ally, the Galactic Republic, over in the Andromeda Galaxy. Also the UNSC is dealing with growing insurrectionist movements and the Storm Covenant. But eventually, the Citadel cries uncle first, and makes concessions to the UNSC. These concessions include reparations to the UEG, the annexation of one-third of Systems Alliance territory, and access to worlds in the Skyline Verge, a region of space, claimed by the Batarian Hegemony.

2555-2561: UEG enjoys peace in it's time, and an economic boom, while the Citadel falls into Economic Stagnation.

2561: The Sith Empire, having defeated the Galactic Republic and ceasing control of the entire andromeda galaxy(star wars galaxy, for sake of this story), expands into the Milky way Galaxy. They bite off territory from the Citadel Govermants, which can't do much about it considering the poor economic development, and make the Batarian Hegemony an Ally and military base for the Empire in the region. This puts them on the Border with the UEG Frontier worlds. The Batarians, backed by the Sith Empire, demand territorial and financial concessions from the UEG, who adamantly refuse. This blatant refusal of the Batarian's demand, and by extension the Empire's, leads to a declaration of war on the UEG, who mobilizes for war and gives emergency war time powers to the UNSC. The Empire underestimating the resolve of the UNSC, is surprised to see the UNSC amassing for an all out brawl.

There will be no surrender or mercy!
