Date: April 17th, 2552.

Location: Charon, near Pluto.

The darkness of space was filled with the trillions of stars that lit it up. What was also lit up space were the lights of the spaceports, military stations and UNSC ships that travelled around Charon. This one small world had been colonized shortly after the discovery of the second Sol. But everyone feared that it would also be the first target for mankind's enemy.

That enemy was the Covenant. A coalition of alien races formed under one banner to destroy mankind. They were made up of Grunts, known as Unggoy, Jackals, known as Kig-Yar, Elites, known as Sangheili, and Hunters, known as Mgalekgolo. The war between humanity and the Covenant had been raging for just over a year. But in that one year, all of the planets humanity had colonized in the second Sol had been destroyed.

The Covenant had a major advantage against humanity. Not because it had many more troops or more powerful weapons for It's troops, no. It was because the Covenant had a special tactic called glassing. When they would come across an enemy planet, they would destroy the defences before firing beams of high plasma energy from their ships down onto the surface of the planet turning It's surface into a mineral called Lechatelierite, which is similar to glass, rendering it uninhabitable. The Covenant used this method on many planets colonized by humanity.

Humanity needed help in the war against the Covenant, so they began making special bodysuits to aid them in the war against the Covenant. However, the Covenant had launched an attack on Reach, destroying It's surface using the glassing technology. That attack also wiped out the entire taskforce. Only one member survived, but no one in the UNSC had heard from that member or anyone from the ship she was on since it fled Reach. The UNSC commanders believed that the last taskforce member was dead and were already thinking how long the rest of humanity had until it was as well.

Today was like any normal day for Charon and It's inhabitants, except for the captain and crew of a UNSC ship

From the surface of Charon, a large shape flew up into space. It was a large ship with the front half pointed like a diamond and the rear half ending in the shape of a large rectangular block. There were four large engines sticking out of the back of the ship. Along both sides were several large square shaped holes. Half-way down the ship, sticking out forwards on a small spire-like section of the ship, was the bridge. It was circle shaped on the front and was square on the back. The inside of the bridge had a large metal door on the back wall. The bridge had windows along the sides and the front. There was a long metal walkway that went over a circle shaped hole in the middle of the bridge. In the circle shaped section were workers on computers going over the speed of the ship, It's weapons, engines and distance to target. In fact, the ship's target was Earth. Captain Walker of the Apocalypso, the UNSC ship, was standing at the front window, looking out at the stars. The ship needed to get to Earth as quickly as he could. His crew had only arrived at Charon earlier that morning for repairs to the ship's engines. Why had they?

The day before, the Apocalypso was going through space to spy on any Covenant fleets when a large fragment of an asteroid fell into their hanger. Workers and researchers on the ship went through the rock until they uncovered a small triangle pyramid base object the size of a human hand. It was glowing a white/bright blue colour. No one knew what this thing was so they were going to take it to Earth to research it. However, on the way, the engines suddenly lost all power for a few seconds and fire broke out when the captain ordered backup to be restored to the engines to keep them going, which is why the Apocalypso had to land on Charon.

As the ship flew through space, captain Walker sighed and turned to walk down the walkway towards a large computer panel a few metres in front of the bridge's door. He was a tall man about thirty four years old and was wearing a high ranking UNSC captain's uniform. He had been in the UNSC for fifteen years. He started off as an engineer and gradually worked up through the ranks to becoming a bridge worker. He became a captain when the Apocalypso was engaged in a battle with a Covenant CCS battle cruiser over Takra. When the captain had been killed by Covenant borders, he took control of the situation and managed to save the crew of the ship and several hundred workers and civilians. He was promoted to captain as a reward for his bravery.

Around the computer panel were several workers. One of them was keeping an eye on the object that was being held in a lab a few floors below the ship's bridge. Apparently, when the engines lost all power, the object's energy level rose high for a few seconds until it went down back It's normal level. Captain Walker approached the computer panel.

"Is the ship alright?" he asked a worker on one of the computer panels.

"Yes, sir," the worker replied turning to look at the captain. "Nothing wrong with the engines and the object's energy level is still in the safe zone."

"That's good," Walker replied. "Okay, I'm just going to contact Lord Hood and let him know we're coming,"

Captain Walker walked up to a communications computer screen. He typed in a code and waited for the signal to reach Earth.

Cairo orbital defence platform

Earth. The home of humanity. Even when humans began colonizing other planets, Earth was still looked upon as the home world for the human species. It still had It's rainforests, seas and mountain ranges scattered across It's surface. That was on It's surface. In space just above the planet, there were sign of human presence.

That sign were the Orbital Defence Platforms scattered through space above the planet. They were mainly named after cities since that was where much of them were constructed and because they hovered over those cities.

The platforms had a large flat octagon-like shaped platform, with several bulges along it that indicated they were bridges and hangers, with a tall rectangular shaped pillar, which was the MAC gun, sticking out from the top of several large platforms connected together to the octagon platform. There was also another rectangular shaped pillar sticking out from the bottom of the platforms connected to the octagon platform. From the left side of the octagon platform were two large pincer-like sections that held a docking bay in place. The docking bay was for UNSC frigates and stealth ships.

One of the main orbital defence platforms was the Cairo. Construction of the platform began in 2348 and it took six years to complete. Orbital defence platforms are a major role in the defence of Earth because they have large MAC guns that can used to fire on Covenant ships. Orbital defence platforms were also in clusters. The Cairo's cluster was, other than the station itself, the Athens and the Malta. They were tasked with defending the eastern half of the Mediterranean if the Covenant attacked Earth.

In one of the bulges, on the right side of the MAC gun, a man, that looked to be in his late fifties/early sixties and wearing a white high ranking UNSC navy uniform with two medals pinned to side of the man's uniform's chest, walked out of a corridor into the Cairo station's bridge. The bridge had a tall platform at the end of it sticking up from the floor. It had holographic computer screens along the top of a control panel which had several workers on it, who were also dressed in white uniforms. Behind that platform was another, that was also sticking up from the floor but was slightly shorter, that also had holographic screens along the top of a control panel. There were several workers on this control panel as well. There were several other doors leading out into other corridors. There were windows along the top and sides of the bridge, which showed anyone inside them a clear view of space.

The man walked into the bridge towards the smallest of the two walkways. His name was Lord Terrance Hood. He was the captain of the Cairo Orbital Defence station and one of the main leaders of the UNSC. He had joined the UNSC in 2530 and had worked through the ranks of the UNSC. When war broke out between the Covenant and humanity in 2551, Hood was given command of Delta fleet, made up of four frigates, six heavy battle cruisers and two stealth ships. He had also aided in defending Takra and Lupo when the Covenant launched their offensive against the human colonized planets. He was appointed commander in chief of the UNSC defence forces on Earth in early 2552 as a reward for his bravery and help against the Covenant.

Lord Hood walked up onto the platform and approached the control panel where a group of workers were.

"Everything going alright?" Hood asked.

One of the workers turned to look at Hood.

"Yes, sir," the worker replied. "And I'm glad you've come here, There's someone hear wanting to speak to you,"

"Thank you," Hood replied.

Hood walked up to the control panel. He rested a hand on a scanning device. A light blue haze came out of the top of the control panel. It formed a square shape. Then, a man's face appeared on screen. It was captain Walker.

"Good to see you, Lord Hood," Walker said, giving a salute.

"You too, Walker," Hood replied. "Why have you contacted us? Have you spotted a Covenant fleet?"

Walker shook his head.

"No, sir," Walker replied. "We have this strange object on board the ship. It's disabled out engines once by draining their power for a few seconds before the engines went back to normal. We're coming back to Earth to see if we can find out what this thing is,"

"Roger that," Hood replied. "How long will you be?"

"Probably two hours, maybe one," Walker replied.

"Okay," Hood said. "We'll see you when you get here,"

"Sir," Walker replied as the blue haze disappeared from the control panel.
