The room was dark. Exceedingly dark. Only the floodlights of Fireteam Crimson provided sanctuary. As the Spartans walked down the corridor, the lights danced across the walls.

“I’ll tell you guys, this is creepy.” Evan said, his eye on his sights.

“I second that.” Grant replied.

“Cut the chatter, you two.” Chris said, and then, as he stepped, a plate sunk into the ground. Chris barely had time to roll out of the way before a white-hot laser sliced through where he was once standing. Chris swore, and proceeded to crouch-walk through, his floodlights on the ground. Taking the hint, the fireteam members did the same. Now scanning the floor, they noticed some plates were cloaked in dust, some plates were clean. Exiting the corridor, the found themselves in a large dome, wreathed in blackness. As the fireteam scanned the room, Chris walked slowly towards the center. Then, lights came on, illuminating the dome. Grant swore.

“More books. Jesus, how many missing labs are we gonna find?”

“I’ll tell you, this is really creeping me out big time now.” Ken said, shouldering his DMR.

“Found the mind.” Chris said, walking to the pedestal. As he removed the mind, the pedestal collapsed. Then, the room began to rumble and shake.

“FUCK! Everyone out! NOW!” Chris swore. As the team made the break for the exit, dodging the now active traps, they exited to a massive, pitched battle taking place. From what they could see, the Covenant were throwing everything they had to breach the UNSC lines. Chris swore, and then, a bolt of lightning struck a snowdrift. The ground began to rumble once again.

“AVALANCHE!” David screamed, as the snow began to cascade down. Worse, trees and boulders were caught in the mix.

“Down the mountain! LET’S MOVE!” Chris said, beginning to slide down the mountainside. The members followed suit. Sliding, jumping, and dodging, the members of Fireteam Crimson desperately tried not to be covered. Then, plasma blasts struck the snow beside them. Chris turned and saw a massive Covie strike force ascending the mountain, accompanied by Wraiths with what looked like snow-plows attached. Chris activated his thruster pack, sending him straight towards the encroaching enemy. Leaping into the air, he dove down and Spartan Slammed, using the lift response to slam again, blasting several small covenant groups. As the other fireteam members slid down, blasting their way through, Chris kept a firm hold on the Second Mind, using his Magnum with his other. Then, an idea struck him. Activating his Hardlight Shield, he mounted the module on his arm, simulating a 21st century Riot Shield. Using the shield as cover for the mind, he blasted, meleed, and dodged Covenant at points, all the while blasting with his Magnum. A screech on engines alerted him to Ken taking down the crew of a Phantom and David shooting the pilots through the cockpit window. Grant and Evan were leaping across the snowplow Wraiths, eliminating the gunners and pilots. Evan leaped backward, cartwheeling to the rear engine. Shoving a grenade into the thruster, he leaped up, with Grant following. The explosion made the wraith flip, propelling the Spartans into the air. Spartan Slamming into the ground which eliminated a squad of Jackals, they continued to blast the enemy. Chris focused forward and continued to blast his way through the still-relentless covie infantry. Six and Zag were on a cliffside above them, with Zag blink-striking enemies, and Six eliminating them. Then, rockets impacted the ground occupied by a large squad of Grunts. Chris looked up and saw Viking-01 fly past, spraying machine gun fire. Setting itself parallel to the Fireteam’s position, it opened the rear doors. Chris jumped in, followed by the rest of the team. Chris took the gunner position on the rear door, while the fireteam sat down. The avalanche continued to cascade, wiping out the remains of the Covenant strike force.Then, a radio call erupted.

“Crimson, this is Miller. Glad you could rejoin us. The Covies are throwing EVERYTHING they have at us. We have unconfirmed reports of Liches as well. We need you down here, Crimson. Get here ASAP. The Equestrians need backup holding the southern defense line. Icebreaker and Forest are already present, but they’re gonna be overrun soon.”

“Say no more, Miller. We’re on it.” Chris said. “Pilot! Souther defense line now!

“Got it!” The pilot replied. As the Pelican began to turn, they could see the full extent of the assault. The UNSC lines were holding firm, but Chris and the fireteam knew they wouldn’t be able to hold out unless the southern line was reinforced.

“Crimson! AA fire’s too heavy! You’re gonna have to air deploy!” the pilot yelled. Chris nodded and motioned to the Spartans and Promethean. As they lined up, the Pelican pilot gave the “OK” gesture. They jumped out, diving into a streamlined posture. Plasma fire erupted all around them. Chris scowled under his helmet.

“My estimates and field data report we only have 15 minutes to reach the the positions. We need to speed up.” Ramos said, his CG face in a war-ready grin.

‘Copy that Ramos. FIRETEAM CRIMSON! WE RIDE HERE, WE RIDE NOW! LET’S RIP THESE BASTARDS!” Chris said, with “HOORAH!” coming from each member. A timer appeared on Crimson’s HUD. As the defense line appeared in their view, Crimson linked up and began to slow their descent. Noticing a neighborhood built on a hillside, he slowly started to dive. When he was within three hundred meters, he began to prep for a sliding impact. Hitting the ground, he rolled and began to powerslide down the slope, with the rest of the team following suit. The team slid down the mountain, while smashing through anything that stood in their way. As they reached the overlook, they activated their mag boots. Sliding to a stop, Zag simply teleported to their position. As they sprinted down the rest of the hill, they came under fire from Covenant squads. Blasting their way past them, They arrived at the main line. Covering behind a large house, which the UNSC was using a field outpost, they restocked their ammunition. With weapons full to bursting, they motioned to one another.

“Ramos, how much time do we have?”

“Nine minutes. Good news, it’s only a couple hundred meters from our position. Bad news, it’s almost overrun.”

“You heard the AI! Let’s move!” Chris said, and the Spartans began to sprint towards the battle line. Arriving at the first set of trenches, they were quickly joined by Icebreaker and Forest.

“Murphy! Sitrep!” Chris yelled, blasting the encroaching Covenant with his Battle Rifle.

“Those Covenant really want to take this line! They’re trying to flank us!” Murphy replied, whilst throwing a frag grenade.

“Copy that.” Chris replied.

‘Chris! My tactical scans say the Covenant have field artillery shelling our main lines. It is also being used for a tactical firebase. If we can neutralize those guns, we might be able to cull their offensive!” Zag yelled, synthesizing more ammunition for his Binary Rifle.

“Copy that! We need transport! NOW!” Chris yelled, and Fireteam Forest broke off. As the onslaught continued, Crimson and Icebreaker were almost out of grenades, and Zag’s supply of Synthesized ammunition was drying up. Then, a massive salvo of rockets impacted, and the Mammoth rolled past, backed up by Scorpions. Forest rolled up in a troop-hog with two additional warthogs full of Marines. As they boarded, the Mammoth blasted a group of Phantoms with the MiniMac. Motioning to Esposito, the three Warthogs drove off, leading the charge against the enemy.

Author's Note

Yes, the battle for Canterlot will be five parts of true warfare for the fate of Equestria. Like how I integrated the Halo 5 opening? The armor upgrades gave them the Spartan Slam and Charge. Plus, I will integrate enemies and weapons fro Halo 5 now. NO CHARACTERS THOUGH. This story is BETWEEN Halo 4 and Halo 5.

RECOMMENDED LISTENING
THe Halo 5 OST song- "Light Is Green." It's the theme for Fireteam Osiris, and the theme used in the opening cinematic. I loved writing to it, so it's kinda indispensable for the story.

Hope you guys enjoy! But the battle is far from over...
