A/N enjoy! This story shall Be dark.


Earth, United States, Texas. Docking installation 0121. Year 2575. 20 years after the Covenant war.


"John hurry!" Cortanna yelled through the COM. He sprinted as fast as he could through the corridors. He saw the sliding door that lead to the docking station of the UNSC INFINITY. Screeches and wails echoed through the hall. They were gaining on him. He hurdled over a knocked over pillar. He rammed into the sliding door, charging straight through the glass. The sky's outside were gray and peach. A foggy green mist was starting to block out the sun. He glanced to the mountains and city in the distance. A UNSC destroyer laid in ruins on the mountain. The city was in flames. He could here the screams and gunfire.

"John hurry! Laskys been ordered to abandon Earth! You have to get out of there before him and the rest of the fleet leave you behind!" Kelly yelled over the COM. John looked back at the docking station he had just left. Hundreds of flood crawled over the building snarling and hissing. Dozens poured out of the broken screen door. John fired what remained of his Gauss Rifle, a special breed of the battle rifle retrofitted with gauss weaponry. The two shots tore through at least a dozen of the combat forms but he couldn't even see a difference in the numbers. He turned an looks at the infinity. He saw a ramp was lowered off one of the lower hanger bays onto the walkway. A spartan in black armor stood on the ramp waving him to go faster. He huffed. John pushed himself to his limits. He accelerated to 65 kph. He had only gone this fast one before which left him with a torn Achilles' tendon. The massive engines on the INFINITY roared to life.

"John were not gonna make it!" Cortanna cried.

"We'll make it" he said calmly. But even he was afraid. It had happened and he couldn't believe it. The Flood, the most dangerous threat to life anywhere in the galaxy, in the universe had returned. He wasn't even sure how. He just remembered the first signs.


Flashback.

John entered the command room aboard the UNSC Carrier Independence. The Arbiter, Lord hood, A grunt named Painsky, Doctor Halsey, Kelly, Linda, and Admiral Parangosky stood around a circular table. Kelly looked up and gave half a smile to him. No one else even bothered to look at him. They all stared at the table. The Arbiter flexed his jaws. John could tell something wasn't right. He walked up next to Hood.

"Sir." He saluted.

"Not today chief... Cortanna show him..." He said gravely. "Aye aye sir" she sighed over the intercom.

John looked at the table. A holographic video pooped up.

"We lost contact with two worlds. The elites world of Reconciliation and our world New Harmony. This is the footage we reviewed from New Harmony. No survivors from either planets." Cortanna explained. John felt worried. New harmony had at least fifty UNSC ships docked. They were colony ships meant to help spread humanity into new reaches of the galaxy. It was highly defended with over 50000 troops stationed on the small world. The video began to play and his stomach turned. He was watching a video feed. Deformed creatures lunged across from one building to another. Marines and ODSTs fought the parasite in the streets. He watched as several marines were torn limb from limb. Gunfire ripped through the waves but as one combat form fell another dozen took its place.

"Where did they get all these troops?" John asked.

"We don't know. They came from beyond the galaxy in sleek, rounded ships." A flood form pulled out an orange biotic sword and cut a marine cleanly in half. Pure forms ran rampant as John watched a family fall victim to the flood forms. He would never forget the screams from them.

"Their back... The flood has returned" Kelly said with both anger and sorrow.

"We must fight them with everything. All of the Sangheili shall fight till the end. We will not allow the parasite to win!" The Arbiter proclaimed as he pounded his fist on his armor.

"Cortanna take us to defcon 1. We are at war" Hood proclaimed.


Brief history of the war.

After this day the UNSC, Sangheili, Mgalekgolo, Unngoy, all joined forces to form the United Alliance of the Galaxy, the UAG.

2562

The Second battle of Harvest. UAG engaged insignificant flood forces and Managed to repel them.

2562

The battles of Arcadia and Harvest. The flood attacked with overwhelming numbers. The Flood used different types of ships rather then any seen within any known race. Flood ships shown to have kinetic barriers and combat forms have biotic abilities making them all the more potent on the battle field. UAG forces engaged, deploying spartan 117 and spartan 087 to Arcadia to halt the spread of flood. Three weeks later both planets fall to the flood. UAG declares martial law and begins mass production of weapons and ships. UNSC ships Mac and point defense weapons are upgraded too triple the original power level by using condensed energy bursts to allow greater acceleration and impact force. Super Mac is doubled in strength by similar technique. HIGHCOM meets and establishes plan Reclamation in case of the worst.

2563

Outer colonies of UNSC and Sangheili empires have fallen. UAG begins production of new ASCENDANCY ship meant to replace INFINITY. ASCENDANCY is twice as big as INFINITY with twice the armaments along with the new Super Compressed Electric Accelerated Cannon which contains three times the power of a Super Mac cannon. Commander Lasky is promoted to Admiral for outstanding leadership in the recent battle of Mocsare IV where Admiral Richards fell In battle to superior flood naval forces.

2564

Jiralhanae and Kig-Yar join the forces of UAG as the flood threat approaches their home planets. Fall of the UAG fleet Retribution in attempted rescue of infected planet.

Battles rage for three months as the flood constantly batter UAG forces on both worlds. UAG begins development of gauss rifle for Spartans. Spartan blue team and Arbiter are deployed to Sanghelios as battle turns for the worst. Fall of Jiralhanae home world ending with Brutes becoming an endangered species.

2565 March

Sanghelios is freed and the flood are defeated at the battle thanks to actions of Spartan 117 and the Arbiter. Sentinels from remaining halo installations join the fight causing a brief respite to UAG forces as they begin to push the flood back. New Gravemind is created within the Galaxy.

2565 August

Flood strikes back and successfully breach UAG lines infecting twenty two planets along with a year long siege of the recently freed Sanghelios. Elite ships begin to fully glass planets to halt the spread of the flood. The second battle for Reach begins. The Battles for Sanghelios and Reach become the bloodiest and most terrifying of the war to date.

2566

Fall of Sanghelios and Reach. Death of several spartan IVs and the spartan III named Ash. Ash sacrificed himself for the crew of INFINITY.

2567

Flood use a daring technique and blitzkrieg straight through UAGS territory effectively splitting off the western and eastern halves of the UAG empire. Cole protocol fully instated. UNSC ships begin to fully MAC and nuke planets to haunt flood infection spread. Gauss rifle is finished and Spartan 117 and 087 save INFINITY from successful flood breach.

2568

After countless losses the Sangheli are endangered. Fall of the Kig-Yar, Unngoy and Mgalekgolo home worlds resulting in the lose Of over 10,000 ships in the battles for each planet significantly crippling UAG forces. Lord Hood, Cortanna, The Arbiter and Admiral Lasky declare standing order Burning Siege. It is now banned to try and save infected planets. Ships are to glass and bombard from orbit to destroy and avoid infection. Western half of UAG planet count at 156 planets. 15,678 ships in Naval force. Eastern half of UAG planets count 150. Naval strength at 40,456 ships.

2570

UAG territory in the west completely falls to the flood. Leaving only the east to fight the flood. Locations of the one hundred and fifty remaining planets are found by the Gravemind. Fall of the inner colonies excluding the recently nuked Reach. Earth becomes last military bastion for UAG forces. Hood and Arbiter consider operation Reclamation which is opposed by 117 and Cortana.

2571

Battle for Earth begins. 30,000 ships are launched in a last ditch effort to defend earth against the attacking force of 1,245,000 ships. ASCENDANCY And INFINITY lead the charge. Spartan IVs, IIIs and blue team are deployed to save Earth.

2572

Flood uses battle for earth as a distraction and assaults remaining one hundred UAG planets. Only 10,000 ships were left to defend the UAGs remaining planets.

2573

Battle of earth reaches tipping point as the Flood capture Asia, Austraila and Europe. UAG fleet above earth down to 13,567 as the battle turns for the worst. Operation Reclamation is deemed a go.

2574

Only twenty planets remain along with Earth in the UAG empire.
Twenty ships split and find the remaining Halo rings for Operation Reclamation. Operation Reclamation is the activation of remaining Halo arrays to free the galaxy from the Flood. Activation of arrays is delayed until the last possible moment.

2575

Earth and planet of Plaskac III are the last UAG planets. Effective naval force of UAG placed at 3,256. Respective populations of each race are around 20 million for humans, 8 million elites, 10 million hunters, 23 million grunts, 2 million brutes, and 5 million jackals.


Current date February 1, 2575

Fall of Earth. Fall of Plaskac III. Operation Reclamation enacted. Rings commenced to fire in fifty nine minutes.

58...

57...

John lunged at the ramp as it ascended. He grabbed on, denting the metal as he hung on. Kelly grabbed his arm and yanked Him up. He gave her a slight nod.

"That was too close.." Cortanna sighed. The INFINITY began its Ascent into space. John and Kelly stared down. They watched as the flood ran rampant and destroyed the once glorious city of Houston. They turned as the ramp closed up and hissed as the airlock finished sealing itself. They began their journey to the bridge.

"I can't believe this... After all this time... I thought we had won..." John said.

"You can't win every time John." Kelly said with kindness. They were silent the rest of the way.


They walked into the bridge. Admiral Lasky was at the command/holo table, staring at the holographic image of Earth. 32 minutes till halo activation. The INFINTY was turning from the raging space battle to face Earth. John caught a glimpse of the ongoing battle in space. Hundreds of UAG ships fought the impossible battle against the thousands of flood ships approaching earth. The INFINITY finally completed its turn. Twenty UNSC destroyers and twenty elite cruisers lined up next to it.

"Commence Order Burning Siege" Lasky said in a grim voice. The ships fire. MAC and archer missiles tore up Earths surface. Cities being incinerated by the powerful rounds. Plasma torpedoes evaporated the now black seas of Earth. The INIFINITY fired its main cannon. The MAC slammed into New York. The city and all of its surroundings vaporized in a giant flash of light.

The Comm came alive.

"Lasky slip space to rendezvous coordinates now! Halos will are going to be activated sooner! The installations are under attack! Order your fleet to enact slip space travel!" Hood yelled. John saw the timer on his HUD jump down from 30 to 5 minutes.

"Cortanna!" Lasky yelled.

"John put me in the INFINITIYs systems!" Cortana ordered. John ran over to the chip slot in the command console and slipped in Cortanas chip. The AI appeared on the holographic table. A slip space portal opened up in front of INFINITY.

"This is Admiral Lasky all ships quickly enact the final steps of the operation Reclamation and proceed to rendezvous point immediately! No questions asked!" Lasky ordered over the over the long range COMs.

The INFINITY moved into the slip space rupture. John glanced one last time at Earth.

The burning and forsaken home of Humanity.


John watched as the Milky Way galaxy came into view. The INFINITY had just exited slip space. It had taken ten hours from Earth to reach where they where even with INFINITYs superior slip space abilities. Two hundred UNSC and elite warships were already there waiting for them.

"Where's the ASCENDANCY and all the others?" Kelly asked.

"I don't know... UNSC RETALIATION where's the rest of your fleet?" Cortanna asked allowing herself to be heard on the command bridge.

"Their gone only twenty of us made it out." A male voice responded a few seconds later.

"Didnt they have five hundred ships still fighting over Plascak?" John asked.

"Impossible for them to all get wiped out so quickly..." Kelly said softly.

"Sir one thousand and Twenty slip space ruptures to our left." A man at a computer console announced.

"Bring us around ninety degrees" Lasky ordered as he leaned against the central holo table in the center of the command bridge. The INFINITY turned to meet the new threats. The ASCENDANCY along with two hundred UNSC destroyers, three hundreds Frigates, one hundred Halycon and Colonial class ships, three hundred Elite Frigate and Destoyers, one hundred Elite Assault Carriers and Cruisers, and Eighteen Elite Super Carriers exited out of slip space ruptures. The Arbiters Super Carrier, Burning Light, was twice the size of the rest. Besides the ASCENDANCY it was the most powerful ship in the fleet with human MAC guns and archer middles equipped on it as well as stationary forerunner beam weapons. It had been designed specifically to fight the flood during the war.

"This is Admiral Hood all remaining admirals and fleet masters report in." Hoof said over the COMs and appearing on the holo table.

"Admiral Lasky reporting in."

"Admiral Stewart reporting"

"Admiral Nakishima here"

"Fleet master Cree Fredum present"

"Fleet Master Kel's Prator reporting"

"Supreme Fleet Master The'l Vadam here." Hood and the arbiter were the two supreme commanders of all UAG forces.

"Admiral Parangosky reporting in" silence filled the void. Kelly glanced out the windows of the Infinity at all the ships around as Parangoskys hologram came into view along all the others.

"We're all that's left." Lasky said grimly. Hood nodded.

"So what's the new plan?" John asked walking up next to Lasky.

"Well Master Chief, Halsey has something in mind." Hood said. He moved to side and held his hand out. Doctor Catherine Halsey walked into view and appeared as a hologram next to Hood's hologram. Parangosky scrunched her eyebrows.

"Guess someone is still sour towards Halsey." Cortana said over Johns private COM, connecting to his suit remotely from the Infinity.

"Thank you Admiral. Well I have a proposition. As it seems we have two options. We split and find a home for humanity which comes with the weakness of separating our remains forces making us even more vulnerable than we already are. Option two... We can head off together in search of a new home. With slip space it is possible for us to find one, but either way our galaxy is gone and we have to find a new one." A grim silence washed over. John let his mind run over things. Where would they go? Earth was humanities home. It had fallen to the clutches of an evil beyond all others.

"Where would you propose we go?" Admiral Stewart finally asked.

"I have already charted a course to a nearby galaxy. It would take a year even with slip space to get there. But we'll need to leave soon so the flood can't follow us." Halsey explained. John tensed at their name. He even noticed the Arbiters muscles tense.

"I say we split." Pargansoky said simply.

"Why?" The Arbiter asked.

"Because tactically it's more sound. Gives us a better chance of survival." She explained.

"Yes but making us weaker at the same time" the Arbiter countered.

"Enough... Admirals and Fleet masters I leave it up to you. Those for the new galaxy and staying together." Hood said. He raise his hand. Slowly yet surely Admiral Stewart, Admiral Lasky, The Arbiter, And both Fleet masters raised their hands.

"Then we go with the majority favor. Prep slip space drives." Hood ordered to someone off screen.

"I'll send the coordinates to each ship an really the orders." Lasky said. Halsey nodded as did Hood.

"Meeting adjourned" Hood said and with that the holograms faded away as each person signed off. Lasky looked over at John.

"Wake me up when we get there?" He said with half a smile.

" No..." John turned and began to head towards cryo bay. A slip space portal opened up in front of INFINITY. John looked back at him. And with his monotone voice said

"Wake me when you need me"


General Obi Wan Kenobi stirred in his sleep. He tossed and turned. He watched as massive aliens with a jaw that split in four, tower over clone troopers. He watched as the aliens tossed them around like rag dolls. He watched as a four wookie warriors assaulted a massive armored being, spikes protruding from its back, orange skin visible through gaps in its armor, a huge metal shield on one arm, a massive green glowing cannon in the other. The wookies were crushed and vaporized. He watched as a woman, with medium length light brown hair, in sleek gray and silver armor fighting both clone troopers and the aliens. A glowing orange blade coming out from her arm as she sliced a small alien in half. She used a biotic blast and blew away several troopers. A being in green metal armor with a golden visor ran through the middle. He ran faster than even a wookie, the being tearing through troopers like nothing. The being was elegant and fluid almost as much if mot more then a Jedi. the being was surrounded by the force. Then everything stopped. The Forces presence was gone and replaced by a cold troopers, aliens, the woman and the being stopped. A voice began to speak.

"I am the monument to all your sins..." A deep terrifying voice said. The aliens ran in fear. The woman feel to her knees and grabbed her head, beginning to rock back and forth as tears streamed down her checks. The being fell to it's knees and stared up. A large creature enveloped in darkness with tentacles and a massive menacing mouth floated in the shroud.

"We are the perfection of life. The purest form. The final evolution." The being said.

"And all shall succumb to us." The scenery changed. Obi wan gasped. He watched as Coruscant burned. Fire riddle it. He noticed several ships along with Republic and CIS ships fighting ships he had never seen before. The green being walked up to him and looked right at him.

"If only you listened we could've saved the universe" it said.

"The Universe?"

"Yes they are a threat to all life." Yoda walked over to them.

"Evil they are. Not even the Dark side dares with these ones. The Force fleas from them. Why did we not see it.." Yoda said shaking his head. Obi Wam watched as the Jedi temple was enveloped in a massive nuclear blast.

Obi wan jerked awake. Sweat covered his forehead and riddled his body. He coughed.

"That was a horrible dream..." He said wiping sweat from his forehead. His mind wandered at a million miles minute. What could be so strong as to threaten the whole galaxy? Who were those beings and aliens? They were like nothing in the archives. He swung his legs over and stretched on his bed. He looked over at the holopad next to the bed. A green light blinked on and off. He tapped on it. A hologram of Clone Major appeared it was a recorded message.

"General Obi wan we have stumbled across s small fleet of unknown origins. The flagship reads 'Normandy' on the front. We have been ordered to not intercept or contact till you arrive. Please arrive soon." The hologram died away. Obi took in a deep breath and cleared his mind of his fears and doubts pushing the dream to the far corners of his mind. He would talk to Master Yoda about it latter. He got and got dressed. He grabbed his light saber and walked out. The force told him this was going to be a long day.
