It has been a month since they arrived on Sanhelios and after the battle against the Covenant, the home planet of the elites now be under UNSC control. Elite citizens seeing the Prophets lies accepted humanity and the UNSC helps them to rebuild their capacity. They work together to help the elites to rebuild their destroyed buildings and streets.

Marines share some jokes with the elites and bound as their hatred towards the elites is no gone ad they understood they are victims of the Prophets lies. At the control room we find Simmons working on the coms to any UNSC with Y/n and Watcher in the room with him.

Y/n: Anything?

Simmon: Trying but no such luck. It's really hate.

Then their engineer enter the room and sees what Simmons is doing. The Engineer approaches the control console and place it tentacle onto the controls and seconds later they got something which Simmons came out and sees it working.

Simmons: Wow! Thanks.

The Engineer let's out a happy noise while Y/n nodes back and calls out through the coms.

Y/n: This is Spartan Y/n-453 to all UNSC channels. Operation: Planet riot is a success. The Elites of Sanhelios are our allies. Does anyone copy over?

After a while they got someone and it sounded like Lord Hood.

Lord Hood: (radio) This is Fleet Admiral Lord Hood here. Good to hear your voice Spartan.

Y/n: Same to you sir. Sanhelios is now in UNSC control.

Lord Hood: (radio) Is that so?! I never thought the day. You did a impossible job here Spartan, well done.

Y/n: We did it together Admiral sir.

Lord Hood: (radio) Glad to hear that. But its a good thing you called because we have a situation.

Y/n: That being?

Lord Hood: (radio) We have gotten word that the Covenant has located Earth and sent in their fleet to invade Earth.

Y/n, watcher and Simmons are stunned by this as Lord Hood also continued.

Lord Hood: (radio) I need all UNSC forces to come to Earth and help us defend. This maybe our last stand.

Y/n: Will do sir. Spartan out.

The foms end and they stood there in silence for a moment.

Simmons: What should we do now?

Y/n looks down at the control console and with a series expression he tells Simmons.

Y/n: Radio everyone to me us at the middle of the capital. We'll tell them all.

(Moments later)

We see everyone gathered in the middle of the capital as Y/n ans his team where in front of everyone as Y/n step foward and informs everyone the situation. Everyone is shocked and whisper among each other as they couldn't believe it that it is happening.

Grif: Well goodbye humanity.

Donut: Oh no not Earth! It like our birth place.

Lopez: (Spanish) I was betting that the Covenant will find it sooner or later.

Y/n: Everyone calm down. I know it is worse but we will not allow the Covenant to destroy Earth. If the Covenant wants a fight.....they will get one.

Junior: My forces will join you.

They turn to see Junior, Rila, Coya and his troops came as Y/n ask Junior.

Y/n: You sure you wanna come?

Junior: Indeed. Our race destroy a lot of humans, showing no mercy and Earth is special to humanity. If we see to redeem our honourable self's then we must defend your important planet.

Coya: It's not just us but also other elites. They too will come and aid the battle.

Y/n: Alright then. I'll contact Lord Hood while we are heading to Earth.

Junior nodes and he turns and bend down to Rila and tells him.

Junior: Son I want you to stay here with Coya.

Rila: But I want to help!

Junior: No son. It is too dangerous. I don't want you to be hurt.

Rila: Okay....be safe dad.

Junior: I will.

He stood up as he turns to Coya and she give him a node while he nodes back. Junior walks over to Y/n and the two of them shake hands.

Junior: Let us fight together and finish this war.

Y/n: Right. Everyone! We're going home!

And so all UNSC and Junior's army got into their Covenant ships that Coya give them and once inside they all take off and leave the planet.

Once they are all in space they active a slip space jump and their ships go through and make their journey back to Earth.

(2 weeks later)

They exit out of Slip space and soon arrived back at Earth. They see UNSC ships and Orbital Defense Platforms ready for anything and at first they were about to fire when Y/n gives out his code which they stand down.

They dock their ship onto one of Orbital defense Platforms and the doors open and they are greater by UNSC marines as they begin to cheer and clap of their return. The Reds, Blues, Freelancers and other Spartans stood there and being welcome back by the UNSC.

Then Junior and his elites came in and all clapping and cheering immediately stop when they see Elites. They were shocked and confused which Junior and the others are nervous but that's when Lord Hood approaches Junior and looks up at the Elite while Junior look down down him.

Junior looks at all marines and then he begins to say.

Junior: Humans of humanity.......we wish to apologise for all the sins we have done throughout the war. Our race was tricked by the Prophets and we feel dishonored because of this. We wish to make things right by any means necessary by helping humanity defending this planet from the Prophets and our own brothers who are still blind by the lies of the Prophets. Please....allow us to help you as a way for our race to be redeemed.

Then he and his two elite guards kneel down as Lord Hood stared at them.

Junior: Please....let us help you.

There was a moment of silence as Lord Hood stared at Junior for a moment. Then he reach out his hand which Junior sees as he gets up straight and then he takes Lord Hoods hand and they shake on it.

This made the marines and any UNSC personal on board to be shocked by this as this moment will be the greatest thing in humanities history.

(Hours later)

We see Y/n in his quarters as Y/n is taking a very shower and after he is done he came out with a sigh while Watcher appeared on his bed.

Y/n: Damn that feels soo good! It feels like years since I've taking a shower.

Watcher: Yeah you smell like shit under the armor.

Y/n: (chuckle) Yeah.....wait? Since when you can-

Then there was a knock as Y/n walks over and opens to be face with John which surprised him.

Y/n: (surprised) John! Bro! Your live! I thought I would never see.....you.

He noticed his armor was beaten up and damaged which he ask him.

Y/n: Yep....you might need a new upgrade.

John: In a minute but for now I need a talk. With both you and Watcher.

He sounded serious so he let's him in. Cortana appeared on John's shoulder which existed Watcher that she's okay as Cortana ask the two.

Cortana: Ask us this.....when you first met the Reds and blues.....they were in a large ring right called...Halo?

Y/n: Yeah. It was huge, you should have seen it.

Cortana: Actually.....we have.

Watcher: Since when?

Cortana: About a month ago. After we left Reach we arrived on another Halo. Installation 04.

Watcher: Fuck! Is that 343 monitor guy still around? That guy is a huge dick.

Cortana: Force. You also said that Halo is a weapon that can wipe out all life correct?

Y/n: Yes. What with these questions?

Cortana: Well answer this.....have you encounter the Flood?

Watcher and Y/n froze for a moment as they look at each other and back to the two.

Y/n: Yeah. We were searching for Church inside of a Flood containment facility and got out of there alive and well. Why?

John: The Covenant unleash the Flood within that Ring.

Watcher: (shocked) WHAT?! THOSE IDIOTS RELEASE THE FLOOD?! ARE THEY NUTS?!

Cortana: Yes however we stop them but that's not important. What is important is how much of a threat they are.

Y/n: I'm sure they are easy to handle? Besides they are just space zombies.

Watcher: Oh no! They are not just like space zombies. They are by far one of the most greatest threats that the universe has ever faced. The Flood nearly wipe out the ancient humans and the Forerunners. It was the reason why the rings are there.

Cortana: To destroy their food.

Y/n: Wait? Was Captain Keys not with you? Where is he?

John:........He was infected and turned into a Proto Gravemind.

Y/n: (shocked) No.

John: The only survivors are mem Cortana, Johnson and other marines and ODST. Still.....it was the most terrifying situation we have ever come across.

Y/n: So how did you manage to trap the flood?

Cortana: We didn't. We destroy the ring in hopes that the Flood will never escape. We use the Pillar of Autumn as a bomb by destroying the core.

Watcher: (shocked) Wow your amazing.

Cortana: (smirk) Thanks.

Y/n: Still I'm sorry what you two have to go through.

John: It's okay. Just glad to be back. What about you?

Y/n: Oh well let's just say those elites that you may saw is on our side.

Cortana and John:....................

Cortana: And here I thought our adventure was crazy.

Watcher: Thought ours was crazy?

Cortana: Well anyways that's good. With the elites help, we may have a chance to push by the Covenant forces.

Y/n: Yeah. I'm gonna grab a hot meal now. Get yourself some upgrade okay bro?

John nodes and he and watcher leave to get something to eat. Once gone Cortana turns to John.

Cortana: We kinda forget to tell him thag we still have the activation index from Installation 04.

John: We'll tell him later.

Cortana: Right.

John and Cortana head off Meanwhile we find Junior looking at Earth as Tucker found him and approaches to him.

Junior: It's beautiful.

Tucker: Yeah. Can't believe we're back home.

Junior: Indeed. Still....I fear that the other humans will not accept our apology. After what our race has done......I fear they will never forgive us.

Tucker: Don't worry. As long I'm here, I'll back you up.

Junior: I appreciate it father.

The two of them hug while some nearby marines just stare at them in confusion as they slowly walk back and just forget what Junior has said.

We see both Junior's ships and UNSC ships now side by side and ready for the full might of the Covenant whenever they will show up. Soon Earth maybe the last battle between the Covenant and the UNSC.

To be continued........................................................
