This story assumes the Shepard lives past the events of ME3 and that the Citadel forces rebuild to peak strength. Also that there are no tensions (at the beginning of the story) between the races of the ME universe. It also assumes that the Human-Forerunner war never happened, and that instead The two groups eliminated the flood (except for a few spores saved for experiments) and have now integrated their societies. They have one Council leading them, one Military, they are one Empire. The Forerunners did still perfect the Halo rings and the Composer weapons, and Promethean Knights can now be made from any sentient life instead of just Humans and Forerunners, or they can be assembled in factories. Mechanical assembly is slower, but then again they aren't at war. They only use the composer weapons if they desperately need troops. All ME relays are intact as is the second Normandy. The Covenant has been formed, but under different circumstances. Their technology is at almost the same level that they are in the game, if not, a little higher. They do not regard the Forerunners as Gods, nor humans as Heretics. If there are any other inconsistencies between this story, and the events of the Halo/Mass Effect Universe, please keep in mind that this is a Fan Fiction, and I am manipulating the elements of each Universe to go along with the story. It obviously will not go along perfectly with the canon story that you all so adore. I hope you enjoy it!

The Didact was at the bridge of his newly upgraded personal Planet-Breaker, the Mantle's Approach. One of the consoles in the bridge was flashing. "Sir, Master Builder Faber is attempting contact us.". One of Promethean warrior-servants called.

"Go ahead." The Didact sat down in his chair. From his chair he was looking through the glass on the bridge that allowed him to see the endless space in front of his ship. A semitransparent black screen appeared on the glass. It flickered, and then Master Builder Faber, in his mostly aesthetic armor appeared.

"Didact." Faber said. "How is your fleet doing? Any Trouble from the San 'Shyuum? "

The Didact suddenly stared angrily at the screen. "You know very well that there hasn't been any activity in this sector for over sixteen months. Just tell me what pointless expeditionary force you want me to escort this time and my fleet will be on its way"

Faber's head looked away for a moment. "Listen, we've intercepted a transmission from the Sol System going to an unexplored part of the Orion Arm of this Galaxy."

"Sol?" The Didact rose out of his seat "We haven't even had an exploration vessel there for over ten Millenia. The last time Humans were there was over three centuries ago when Forthencho was forced to Glass Mars because of a flood infestation."

"Which is why we are concerned," Faber said. "I will need you to take your fleet and head immediately to Erde-Tyrene. Whatever is transmitting these messages is currently on that planet. We're still trying to decode most of the message, but we've definetly found the word 'attack' and coordinates for the Epsilon Eridiani system."

The Didact signaled to the Prometheans working on his bridge, who had overheard the conversation, and they began sending the message to the rest of the fleet. "Do not worry Faber. You tell the Council I only need a few weeks, and this threat will be neautralized."

"Wait!" Faber yelled. "Didact please, we do not want war. We are sending your wife on this mission. If there is some intelligent species out there, we want to avoid a war. She will be in charge of negotiatios. Do not instigate uneccecary violence."

The Didact grunted. "Very well." The Black screen blinked away. The ship turned full to Port, as did all the other ships in the fleet of over 100 ships.


The Normandy was 30,000 kilometers away from the Charon relay. A massive fleet, composed of a Dozen Dreadnaughts, six Carriers, forty-five Cruisers, and over 100 frigates were preparing to jump to a new system discovered by Citadel forces. They were to be met by a Turian fleet and an Asari fleet, the latter responsible for for exploration of the new system and scientific research. Joker ran up to Shepard. "Earth's under attack!"

"What?" Shepard looked surprised, which hardly happened since the Reapers were defeated.

"Massive fleet, unknown origin, they just popped up right outside Earth. Attempts at communication failed, the fleet defending Earth opened fire. The unknown fleet returned fire. Lots of it."

By the time Joker was done talking, the majority of the Alliance fleet had already engaged their FTL drives and were en route to Earth. A detachement from the Turian fleet also notified the Normandy that they were coming to help, as did a small Krogan fleet orbiting Jupiter.


The Didact's ship had just exited slipspace. He saw a Builder ship at the center of his fleet, which was moving in a Spiral formation. The Mantle's Approach moved to center right beside the Builder ship. One of the consoles beeped, and then Librarian's voice could be heard. "Didact, I need you to bring all weapons and shields offline, then scatter fleet, bring a few Picket cruisers. Leave the rest of the fleet here. This way we don't look like much of a threat."

The Didact hesitated, then nodded at the other Prometheans in the bridge, who then relayed the orders to the rest of the fleet. "If these insolent creatures are planning on attacking us, then why not just obliterate them?"

"That's the problem." The Librarian's voice sounded nervous, which surprised the Didact, as she was usually confident about everything. "We've only decoded a part of the transmission, we don't know if they were planning on an attack."

The Didact's helmet formed around his head. "If anything happens…"

The Librarian cut him off. "Just let me do the talking. You can go caress your guns or check on your War Sphinxes." The Transmission ended.

The Didact's ship followed the Builder ship on its approach towards Erde-Tyrene, Earth. They were supported by a twelve small Picket cruisers. Each of which was armed with a few Hardlight Batteries and two Particle Canons. As the ships approached Earth, they saw a massive fleet waiting. Somewhere between 200 and 250 ships, all varying in size from a few hundred meters to a kilometer were zipping around Earth. The Forerunner ships had their shields lowered and their weapons offline. This made the Didact feel very uncomfortable. Suddenly, the window on the Bridge flashed red. "Sir, one of the ships is trying to hail us, but they're using electromagnetic frequencies. They won't be able to receive our messages, and it'll take me a while to configure the comms array to electromagnetic frequencies." The consoles were flooded with messages from the Builder ship and the Picket cruisers, all reporting the same problem. None of the ships changed course however. They remained on a track to Earth. Suddenly, the Picket Cruiser in front of the Builder ship was bombarded with rounds traveling extremely fast. Within a few seconds, the Ship was falling apart.

"Tell all ships to put their shields on!" The Didact yelled. "Bring our weapons online, focus fire on their largest ships!" The Builder ship was hit with dozens of the like slugs that tore the Picket crusier apart. The bridge of the Builder Ship was on fire and the engines were down. The Weapons were unresponsive and the Shields were just coming online.

"Sir, Particle cannons are online, Hardlight Batteries returning fire, and the Shields are at full power."

"Good," The Didact smiled. "Call the rest of the fleet. Let's show these weaklings some Forerunner firepower."
