Authors Note: Hello everyone! New author here. This story is mostly an attempt to practice my writing skills, and is actually my first time writing anything ever! So it probably won't be too great, but might as well give it a try.

Chapter 1: Super Soldiers and AI Constructs First

The first thing he felt was cold. The icy sensation gripped his entire body, reaching every cell. He pushed the biting pain of the cold to the back of his mind; he had bigger problems to worry about.

Where was he? The memories started to come back. Reach. Halo, the Ark. The nonstop battles he had fought since he was first brought on board The Pillar of Autumn. As the memories came back, he looked around. He was inside the cryogenics bay of the Forward Unto Dawn. All he could see was the frosted glass of his pod, light faintly shining through. Where is Cortana?

A shudder running throughout the pod brought him from his thoughts, and he could hear the faint whirrs of the pod's door activating. The door opened, and he noted that the lights were set to their emergency power status. Artificial gravity appeared to be disabled, with ice crystals floating haphazardly around the room. As he floated out, he spotted Cortana on her holographic pedestal in the middle of the room.

"Welcome back, Chief. Have a nice nap?" she said, a smirk on her face. "As nice as cyro gets. Where are we, Cortana?" he asked as he shook the effects of cyrosleep off himself. Cortana frowned. "Unknown. All nearby systems do not match anything the UNSC has on record, the same as when we first arrived."

He paused his recovery to look at her. "Why did you wake me up, then?" Cortana brought up several sensor readouts on his heads up display. "Approximately twenty minutes ago, I detected a nearby gravitational field with what's left of the Dawn's sensors. We've been drifting towards it, and now I can confirm it's a planet. It's going to pull us in for a crash landing."

He wasn't one to sit around while listening to this information, so he began to make his way to the ships armory, pausing to grab Cortana's AI chip from her pedestal. "Is the planet populated?" he asked, thoughts going to a possible undiscovered world. "Unknown. We're too far to tell, and with the state of the Dawn I won't be able to until we're burning up in the atmosphere." Cortana informed him.

He thought about the situation as he floated in the silent wreck. He didn't like going into an unfamiliar area with no information, especially when alone and cut off from friendly forces. He still held out hope that it could be a frontier UNSC colony world, but he didn't rule out an unexplored or Covenant Loyalist planet.

"Is there any possibility of a safe landing?" he asked, hoping he could salvage the remaining half of the Dawn. He'd rather not be stranded without any UNSC transport, damaged as it may be. "Negative. The Dawn is at 25% functionality. The reactor is on emergency power, and the engines are completely totaled. The Dawn will not survive reentry intact." Cortana gravely informed him. "We're going to have to find another way down, and I'd prefer it wouldn't be by jumping ship. You've done that enough to last a lifetime or two." Cortana said as he opened the armory.

Weapons floated aimlessly through the room, unsecured in the chaos of the Battle of the Ark. Dozens of firearms are waiting on their racks, their users never to return. He paused to grab a floating M6D Magnum, and secured it to his hip. The oversized pistol would be useful for taking out armored targets with its High Explosive rounds. Cortana sighed. "I'd try to dissuade you from taking too much, but I know how you Spartans are with your toys." He snorted in response. "It never hurts to be prepared." He said as he grabbed an MA5C Assault Rifle off the wall, along with its respective ammunition.

"We've got about thirty minutes until we hit the atmosphere of the planet. The Dawn's logs indicate that all of our pelicans were shot down on the Ark, but there are still twenty ODST standard SOEIV's left, ready to be deployed. We'll have to launch right as we hit the atmosphere, as long as there's a suitable landing point below us." Cortana informed him as he gathered ammo, grenades, and various other supplies he'll need in the field.

As he did so, something caught his eye in the corner of the room. A jet black crate, stamped with the seal of the Office of Naval Intelligence. Opening it, he found it to be filled with the UNSC's experimental field weaponry, including the M6 Grindell/Galilean Nonlinear Rifle, informally known as the Spartan Laser. Looking at it, it appeared to be the very same one he used on the Ark. As he picked the huge weapon up, his thoughts strayed to its last user, Sergeant Major Avery Johnson.

Johnson had been one of the closest things to a friend he had outside of the Spartans and Cortana, and had both survived the Fall of Reach, Halo, and the Battle of Earth. They had fought and bled together on the battlefield, and had formed a bond of respect and gratitude for each other. Johnson was killed by the rampant Guilty Spark, who had betrayed them at the very end. The Chief had ended the traitorous AI's life, but at the cost of Johnsons life.

They had lost a lot of good people during the war. Johnson, Miranda, Captain Keyes, his Spartans... He only hoped their sacrifices were worth it.

"Chief, we're approaching the planet. Detecting standard earthlike environment, 75% ocean surface. A prime candidate for a colony world. We're going to set down over the largest continent, near the mountains." Cortana informed him. "Strange, I'm detecting lots of orbital debris. It appears the world's moon has been heavily damaged, completely shattered on one side... Doesn't look natural."

A shattered moon? He couldn't think of anything that could cause that level of damage, aside from the UNSC's NOVA nukes. It didn't matter for now, he had to focus on the situation on hand. He started to load up some robotic dolly's to transport weapons and ammunition to the ODST drop room, affectionately nicknamed "Hell's waiting room" by Marines. He made sure to pack supplies for everything, he didn't know how long he'd be on this world. Equipment failures or starvation could pose a serious problem if he was forced to stay here for a long time.

"The pods are prepped to launch. I'll guide them down alongside us, hopefully they'll land near our landing zone." Cortana said.

Suddenly, a loud metallic groan sounded throughout the ship.

"Hurry Chief, we don't have much time left. The Dawn is picking up speed, we'll be hitting the atmosphere in ten minutes." Cortana worriedly informed him.

He made the final preparations, and climbed into the pod that Cortana designated for him. He paused to look at the name inscribed inside, Gunnery Sergeant James Anderson. Hopefully the Sergeant had made it off of the Ark safely. "We're hitting the atmosphere now. I'll leave a fragment of myself in the ship's systems, do my best to guide her down." Cortana said. He finished strapping himself in, and did the Pod's final pre-launch checks.

A mechanical arm lowered his pod over his launch port, as did nineteen other arms for their respective pods.

"Standby for launch. Hang on, Chief." He saw the other pods launch in front of him. With a sickening jolt, his pod lunged downward into the turbulent, fire filled air.

Codex:

M6D PDWS: The M6 series being the most popular UNSC sidearm, the M6D takes "sidearm" to the extreme, with its huge size and 12.7x40mm M225 SAPHE (Semi-Armor Piercing High Explosive) rounds, making this pistol horrifyingly deadly to infantry, destroying both armor and energy shield alike

MA5C ICWS: The MA5 series has been the UNSC's mainline rifles for over a hundred years, and the MA5C is one of the latest models. It boasts the standard features of the MA5 series, featuring an air cooling system, being gas operated, electronics suite featuring ammo counter, compass heading, and other functions. Highly customizable and reliable, the MA5C is a UNSC marine favorite.

M6 Grindell/Galilean Nonlinear Rifle: The M6 "Spartan Laser" is one of the UNSC's most devastating handheld heavy weapons. One of the only UNSC battery powered weapons, the Laser is capable of penetrating almost any target, including tanks. Firing a high powered laser, it is capable of destroying just about anything its fired at. Nicknamed the "Spartan Laser" due to it being developed as a part of Project GUNGNIR, alongside the Mjolnir Powered Assault Armor/[G] variant.

Single Occupant Exoatmospheric Insertion Vehicle: Commonly abbreviated as SOEIV's or simply HEV's, these drop pods are most commonly known to be used by the UNSC's largest special operations branch, the ODSTs. These pods allow for ODSTs to quickly get into a fight, or secure an area for incoming friendly forces.
