AN: So I wasn't sure if this was ever going to move past a one-shot, but it has. I actually now have a list of ideas (many coming from an awesome reviewer) and I'll probably post more later on. I'm going to leave this story marked as "complete", though, because at any point it is.
WARNINGS: Language and violence. I don't think the violence is gory, but others may disagree. And Johnson has a potty mouth. I tried writing this without that, but it just didn't fit.
Disclaimer: I do not own Halo or Harry Potter.
Voldemort
The arrival of the strange quartet to Hogwarts had not gone unnoticed by Lord Voldemort. He was, in fact, very informed of the group's public activities at Hogwarts. It was because of the group's actions that he considered them to be somewhat of a threat.
So when he heard that the four soon-to-be-sixth-years were taking a walk through Little Hangleton, he decided to preemptively remove them from the equation. It should be simple, after all, to do away with four pubescent teens just out of their OWLs year, no matter how talented. The Dark Lord was so confident, he took only Crabbe and Goyle senior alongside Wormtail with him. The Death Eaters were also only meant as spectators. The foursome marched down to the town, sending muggles scattering at their presence. It didn't take long to find the Hogwarts students.
"So, three young mudbloods and their pet beast have decided to visit. Do you, perhaps, wish for protection from the oncoming storm? I hate to disappoint, but there is no room for the likes of you amongst my ranks."
The four time-travelers turned to face the three dark wizards. Their faces were various mixtures of confused and annoyed.
"I'm sorry, I don't recall being introduced. You are?" Cortana somehow managed a sweet tone with undertones of steel that sent shivers down her companions' spines. The dark wizards did not pick up the waning.
The snake-faced man drew himself up, attempting to appear more imposing. "I am the Dark Lord Voldemort!"
It looked like the Dark Lord was going to say more, but was interrupted by a snort from Johnson. They eyes of the dark wizards focused on the teen as he lit a Sweet Williams Cigar (and where did he keep getting those from?). "Yeah, whatever, snake-face. You're obviously the bad guy, so you'll monologue, we'll annoy you, and everyone ends up fighting no matter how this goes down. Can we just skip to the end already?"
The dark wizards looked furious, but it was only Voldemort that reacted. "Avada Kedavra!"
Voldemort had made a Very Big Mistake. That mistake was willingly facing Blue Team in combat. This mistake could be broken down into two smaller mistakes. These mistakes were perfectly understandable, as Lord Voldemort was rather ignorant in regards to Blue Team.
The first mistake the Dark Lord made was assuming that Blue Team couldn't defend themselves with magic. The time travelers had worked hard on their newfound skill, and all of them had in fact reached or surpassed Albus Dumbledore's level of skill and knowledge. They had kept the majority of their skills secret by practicing away from prying eyes, thus keeping Voldemort (and others) ignorant.
The Dark Lord's second mistake was attacking them off of Hogwarts grounds. For most of the year the foursome only carried weapons that could be easily concealed on their person, as openly carrying weapons at Hogwarts earned detentions. Outside of Hogwarts, though, they could carry whatever they wished. This meant that they generally walked around armed to the teeth.
Perfectly understandable mistakes considering Voldemort's ignorance, but very deadly ones.
Johnson dove to the side to escape the Killing Curse. Cortana used the time to take two steps forward and throw up her hands. A shimmering dome appeared over the time travelers as Cortana cast a wandless shield over them.
The Master Chief unslung his assault rifle from his shoulder and took aim at Voldemort's chest. Johnson scrambled to his feet and joined the Chief with his DMR. The Arbiter drew a small device from its holster on his thigh and activated it, the energy sword igniting with an electric hiss.
A barrage of spells hit Cortana's shield, making the surface ripple and shimmer hypnotically. It didn't take long for the dark wizards to realize that they were wasting energy and to stop tossing spells at them.
As soon as they did, Cortana dropped the shield. Johnson and the Chief shot off in opposite directions, firing as they ran. All three dark wizards hit the ground in seconds, riddled with bullets.
Cortana had drawn a pistol and followed the Chief, while the Arbiter had charged forward under Johnson and the Chief's cover. The sangheili was intent on skewering at least one of the dark wizards.
The Arbiter made it to them uncontested, and gladly plunged his blade into Wormtail's chest. He managed to quickly grab a hold of Goyle senior and haul him into the air one-handed. The Death Eater was run through as well, his screams echoing off the nearby buildings.
Voldemort had somehow managed to stand and draw his wand while this was happening, and the human time-travelers couldn't fire at him because of the risk of hitting the Arbiter. Fortunately the sangheili warrior noticed at the last second, and dove away from a Killing Curse aimed at his head.
Johnson and Cortana had a clear enough line of sight to plug several shots into the Dark Lord's chest, but quickly stopped. Voldemort swayed, barely alive, then screamed when the Master Chief stabbed a combat knife between the vertebra of his neck.
"Take that, jackass." Johnson spat.
The Chief stalked up to Crabbe senior, who was desperately trying to crawl away from the Spartan. Without hesitation he put a round through the man's skull. The Death Eater had killed at the very least, the Chief held no remorse for executing him.
"An excellent kill, John." The Chief turned to face the Arbiter, who was examining the Dark Lord's body.
"Bastard deserved it." A low moan sent chills down both warriors' spines.
"Wha-"
"Prophecy." All three males focused on Cortana. "There must be a prophecy involving him. Prophecies magically bind the fate of the individuals involved, forcing them onto specific paths. At least, true prophecies do. Which means that we're physically incapable of killing him until the prophecy is fulfilled."
"Great," Johnson growled as he chewed on his cigar, "we're gonna have an immortal dark wizard on our asses now."
The Arbiter snorted. "We won't if this one knows what's good for him."
The Master Chief was inclined to agree. "Maybe we can't kill him, but we can make him suffer and kill off his followers. I doubt he'll bother us."
"Plus the only time he knows where we are is when we're at Hogwarts, and he won't attack anyone there." Cortana added.
"Wait." Johnson looked confused and slightly concerned. "Then how'd he find us?"
Cortana looked thoughtful. "We must be near his base of operations, which would mean that he has people on patrols and detection spells. We're near where he was resurrected, this place probably has some sentimental or strategic value for him. It would only be logical for him to hang around."
Johnson's face broke into a maniac grin. "Then we should blow the place to smithereens!"
Cortana put her hands on her hips. "Absolutely not!"
"I am with Johnson on this one." Thel rumbled. "It would improve this place a great deal."
Cortana rounded on John with a don't-you-dare look on her face. He was not about to oppose his angry date. "Too many civilians. Best to leave it alone."
Johnson started imitating a chicken, clucking and strutting around as Thel scowled in mock-betrayal. Cortana flicked her wrist and sent a silent spell at Johnson, and the purple ball of light transfigured him into an actual chicken.
John chuckled as Johnson started squawking angrily and flapping his wings in distress. Served him right.
Cortana rounded on Thel, who held up his hands in surrender. "We shall leave the town in one piece. Understood."
With a satisfied smirk Cortana lowered her hands. Thel retrieved Johnson, tucking the indignant chicken under his arm.
"Let's get out of here. The should-be-dead Dark Lord's creeping me out." John grunted.
"Agreed. Back to base?"
He nodded affirmative to Cortana's question, but then had a thought. "One minute."
John pulled out a piece of paper and a pen from his bottomless bag that went everywhere with him. He scrawled a short note, dropping it in front of Voldemort's face. "Alright, let's go."
Later, Death Eaters would find and retrieve their Lord. One of them picked up the note and passed it to the inner circle. Once Lord Voldemort had recovered enough to demand the note, it was retrieved for him.
The note itself had been magically sealed so that only Voldemort could read it. So despite their best efforts, nobody had any indication of what the note's contents were. Naturally, Voldemort was both enraged by and curious about the note.
As soon as his hands touched it, the seal broke, allowing the note to be unfolded and read by the Dark Lord.
Dear Snake-Face,
This is a warning. Today we beat you and your lackeys into the ground using minimal magic and a couple of muggle tools. We killed your minions, and would have killed you if it weren't for the prophecy keeping you alive. And there is a lot more where all of it came from.
If you attack us again, we will find your base, and burn it to the ground. Anyone who makes it out alive will be executed. If you harm any of my friends, I will lock you up and make today look like a pillow fight. Every day. For the rest of your life.
Leave us alone. Or else.
-The Demon
Lord Voldemort lowered the note, hands trembling slightly. He had obviously missed something somewhere, because these were not children. These were not even normal people. No, they were something else entirely. Something very dangerous, and he was fairly sure that they were not to be messed with.
"Bellatrix!"
"Yes, my Lord?"
The Dark Lord gave his lieutenant a serious look. "There is a group of four students attending Hogwarts. One of them is a nonhuman, and the others are mudbloods. Tell the others that they are not to be attacked, for any reason. Am I understood?"
Bella frowned. "But my Lord-"
"Do as you're told!" Voldemort roared.
The insane witch scurried away to do his bidding, while he returned to the letter.
-The Demon
Yes. Mudbloods or no, these four were best left alone.
AN: I figure that some of you might be interested in knowing how powerful Blue Team is in terms of magic, so I decided to put a little note in here. Basically all four of them can do silent magic and at least basic wandless magic, with Cortana and the Chief having mastered that skill. Johnson's core is a bit larger than average, Cortana's is large, the Arbiter's is larger than hers but his control is poor, and the Chief has an absolutely massive core and a lot of control. The Chief also likes magic the least out of their group.
