"They think of us as vermin to be exterminated, eaten for food and to be enslaved. For five decades we have lived in fear of the Brutes; the Jirahanae and their savagery. No more, this will no longer continue. We stand on the dawn of a new age, an age where humanity will no long cower in the shadows and live in fear. No our Empire will stand strong and firm against all foreign aggression that entrenches upon us. We. Will. Not. Bow. The Age of fear is over and now the Age of Man; of Empire; of Reclamation has begun."

-Fleet Admiral Harper to the UNSC Expeditionary Force prior to the Fall of Dosiac; Second Great War, 2585.

UNSC Ultra Heavy-Carrier Judgment Day, December 2674.

The Combat information Center of the UNSC Expeditionary Force Flagship was vast, dozens of Officers and Enlisted personnel created a constant buzz of noise as they went about their duties. Assisting them were hosts of UNSC Dumb AIs whose blue colored holograms were projected on pedestals scattered around the rectangular chamber. The CIC much like the Bridge of the Carrier were located in the center of the fifteen-kilometer in length warship. With forty thousand Marines, twenty five thousand Sailors, over fifteen hundred Kukri Strike Fighters and Scimitar FTL Bombers, twenty four hundred plus CIWS platforms, three thousand Reaver missile silos, the ship earned its name; even without considering the Carriers main armament.

Surrounding the flagship were thousands of vessels from the grey plated, purpose built war ships of the Reclaimer Empire's UNSC, to Task Forces of the New Covenant, Inter mixed with them were the haphazard in appearance ships of the Eayn Protectorate, swept-wing vessels of the Turian Hierarchy, Angular ships of the Systems Alliance Navy and countless others.

And it might not be enough, Fleet Admiral Ryan Zhang, commanding officer of United Nations Space Command Expeditionary Force thought to himself as he watch the holo-table project the Allied Races Defense Initiative First Combined Fleet. For every ship he had the Archenemy had nearly a dozen, and with the majority of the ARDI Combined Fleet reliant on Element Zero that made the numbers disadvantage worse. But there was no turning back, not after The Event.

"Sir, all Battle-Groups report that they are ready for the jump." His Aide-d-camp Bradford; a UNSC 'smart' AI reported as the AI tapped his earpiece. Zhang nodded, he didn't need the verbal report; he had check the report Bradford had sent to his Neural Implant, but having the words spoken made it all the more real. Home was lost as were countless other worlds, a hundred billion dead. But now… now there would be retaliation.

"Prepare the NOVAs, have the Infinity classes do the same, and open a General COM Channel the Fleet." Alea Icata Est, No turning back the Fleet Admiral reminded himself. However stated that was the roll of the United Nations Space Command Expeditionary Force; to engage the enemy and keep the battles from the worlds of the Empire no matter the cost, just as the UNSCEF had done in its inception during the Second Great War in order to prevent a repeat of the First Great War

"Yes sir." The AI acknowledged before turning back to face Zhang. "Channels ready."

The Admiral unconsciously straitened his dull gray Naval Uniform, which when both shoulder plates were included was more like no to mention acted as personal armor and cleared his through as he accessed his Neural Implant and activated the channel sent from Bradford. "Men and Women of the Allied Races, for nearly a decade we have fought the loyal remnants of a hated interstellar empire, now we face something worse, beings as old as time itself if not older. Being who laid the Forerunner Empire low when it was at its height. We are out numbered, out gunned, but not out matched. The Event had murdered uncountable billion and has destroyed homeworlds. We cannot hold back, if we fail all life will be enslaved, cattle to have their minds stripped and clouded. When the portals open we will enter the domain of the Archenemy. The howling dark; a place whose very existence is controlled by the will of our enemies. This war; the battle will be the defining moment of each of us, of our civilizations. We fight for our brother- and sister-at arms, for those left at home; our friends, our families, our mothers, our fathers, our brothers, our sisters, our children. One final effort is all that remains. For the Reclamation."

Fleet Admiral Ryan Zhang moved to stand before the Combat Information Centers primary Holo-fleet-command table. This is it he thought. "Recon vessels move in, all other ships prep weapons and advance on my command, reserves stand by."

Zhang watched as the stealth vessels moved into the portals, their crews knew what was need of them in the coming battle. "Assault Group… Advance." Once more unto the breach.

A/N: This is a AU of my pre-existing story Advent of the Reclaimer empire, I have been on a hiatus due in part to real life for the past four months and have only now began to start writing again. As to why I have started an AU instead of a new chapter is that I have been suffering a mix of writers block and new plot ideas that would fit in my preexisting story.
