Kestria

"Sky... You've accessed restricted files classified by the Office of Naval Intelligence, and have been sentenced to death." Commander Palmer said as she entered Sky's quarters. Sky was a Spartan 4 Foxtrot, not only one of the greatest, but a Fireteam leader. She led team Daylight, a five Spartan team that, despite most being savage killers, became her family.

The Spartan Foxtrots were a rather interesting part of history. It started with 5000 individuals in 2535. Most individuals died in augmentations due to the 4/5 chance of survival. That was known as the Foxtrot 3 program. Most who weren't killed in augmentations, the 1250, died in their near suicidal missions against the Covenant. These were usually small operations, as the Foxtrots were a well kept secret.

On her most recent mission, she had found out something that had been kept from her. A carefully guarded secret by ONI, to make Sky join the Spartan 4 Foxtrots willingly.

Her brother.

Still alive, Spartan 4728 had been taken to the Spartan 3 Foxtrots in 2539. She however, had seen her brother marked as deceased, being separated during the invasion of Kholo by the Covenant.

"Sky, since you're one of my favorites, I'm gonna help you out of here. Pelican is docked in a hangar nearby. I don't have clearance, so finding your brother is up to you. Good luck." Palmer said.

"Thank you." Sky said, for the first time. Palmer understood her sincerity as she left the room.

Old Covenant shipyards, Sanghelios

4728 walked with a small squad of Marines, watching for suspicious behavior, which was getting greater and greater.

Ever since Jul M'dama sent some of his Storm Covenant to Sanghelios, the planet had been on full alert. The reason 4728 had a small squad of Marines with him was to keep citizens calm. If the Sangheili saw a Demon, and one that had disabled so many Covenant soldiers, they'd freak out.

Which had proven possible on several occasions within the past few days that had one such Sangheili raise a weapon on the soldier. It didn't end well, and communication has been a little shaky since.

When an unidentified Pelican exited Slipspace, it only caused more of a problem.

The UNSC and Covenant had agreed to limit the amount of soldiers garrisoned at Sanghelios, so reinforcements of any kind would probably throw the alliance down the drain.

Sky knew what she would do was to throw a wrench into ONI's plans. It was also going to get her to her brother. Her plan was to fake a Covenant rebellion. She checked to make sure the six plasma grenades on her belt were ready. Traitor kills would be necessary to complete this mission.

The Pelican touched down in the Hangar of the Covenant space station. She activated her camouflage and walked away from the ship as Marines investigated it. With her, she carried Autosentry, but that was her go-to in combat missions, or to get out of a tight spot in stealth.

Marking her brother's Friend or Foe (IFF) tag, she tossed a plasma grenade into the group of Marines gathered at the Pelican. Almost immediately, alarms sounded, and the station was alerted to the attack. Her brother's IFF moved to her side of the station.

"Perfect..." Sky whispered. She crept through the halls carefully, waiting for the conflict to begin.

Coming into a storage room, she hid behind a few boxes next to an Elite holding a Covenant Carbine. A human soldier and an Elite officer were arguing in the center of the room, and it started involving all the guards. Pulling out her own Carbine, she fired four shots from her Carbine, killing the Marine.

The others began fighting. One marine reported the Sangheili engaging them.

"This is Delta 3 27, Elites killed our captain, help!" Sky heard one yell as she crept toward the surveillance camera, and disabled it, taking the memory chip.

Sky left and saw more Marines arguing with Sangheili. She tossed a plasma grenade over the elites and into the crowd of marines. The Elites glanced behind them, and saw nothing as the humans opened fire after recovering. Sky had already moved further toward her brother.

Ascending a floor, UNSC engaged Elite forces, which swiftly killed the humans. Sky's invisibility ran out, so she pulled out her shotgun, and killed the elites, spinning to get all the targets.

She then advanced. The station was in chaos, the UNSC garrison and Sangheili forces engaging. Sky just walked through the combat, reaching her brother's IFF location. Sky took a deep breath, and exhaled.

She opened the door and found her brother engaging the Sangheili as well, using a DMR. Sky assisted her brother, killing ones that got too close with her shotgun. After they stopped for a bit, her brother decided to ask questions.

"Who the hell are you? One of those asshole Spartan 4s?" 4728 asked.

"I'm Sky, your sister from Kholo, remember, Joey?" Sky said, ignoring her brother's abrasiveness. She knew her brother would probably say that, but she knew he'd probably get nicer as she got to know him again.

"You're dead." 4728 said, looking at her through his blue visor.

"No, I'm not. ONI made it look that way. I've got a Pelican in the Hangar that'll get us into Slipspace." Sky said.

"Sky... How do I know if you're really my sister?" Sky paused as she heard him say that.

"You've got to trust me." Sky said. 4728 paused, and thought.

"Alright. It's nice to have you back, Sky!" 4728 said, hugging her. If it wasn't for her armor, Sky would have died from the hug. 4728 was half overjoyed that his sister was alive, but still just a bit of skepticism remained. Sky hugged back, and they went to leave.

"What was all that stuff about asshole Spartan 4s?" Sky asked as they rounded a corner.

"One Fireteam worked with me before. They were pretty much jackasses and tried to attack me this one time on the INFINITY. Sky, as you can tell, you've gotten bigger than me with your augmentation. That's why they gave me a hard time. I kicked their asses, and was almost sent to the brig by Commander Sarah Palmer." 4728 explained. By that time, they'd reached the hangar, which was occupied by more Sangheili and Marines. The UNSC were falling back.

Engaging and killing elites that got in their way, the duo reached their ship. Sky began the exit procedures, and started flying away.

In space, Covenant ships and UNSC ships began firing at eachother. Sky just barely missed getting hit with a plasma torpedo. Two orbital Banshees flanked them and peppered the back of the ship with small plasma bolts. Two Longsword Bombers flew by and destroyed them, moving on to other targets.

"That was close." Sky said, exhaling loudly.

"Where are we going?" 4728 asked.

"Home." Sky said, engaging the Slipspace drive.

The Pelican shook as it was thrown off course, jumping to a system in the middle of uncharted space.

When it finally exited, it looked like a common colony world was out there, but little did they know, it was where their destinies lie.
