A Grimm Knight Chapter 1

Ozpin was a man that had seen many things in this world; war, famine, discrimination, the list was endless. Yet, in the centuries that he had walked the face of Remnant, nothing could have prepared him for what he had just seen.

"Impossible," he muttered.

"That's what I said when I first saw it," his secretary, Glynda Goodwitch, agreed.

Their shock wasn't unfounded, any experienced Huntsman that saw this video would be just as dumbfounded as they were. For years there was one well known fact about the Creatures of Grimm, more commonly known as Grimm, and that was that they sought to destroy mankind. It did not matter if you were human or Faunus, the Grimm would seek you out and destroy you. However….

"Hey, check this out," the voice of a young boy spoke from his monitor.

The video that the two of them were watching was perhaps one of the most infamous at the current time. The video depicted a horde of Grimm attempting to invade the town of Soleil. Under normal circumstances this would have been a horrifying ordeal to watch. The idea of just sitting in his office as an entire town was laid to waste was just….he couldn't even think of it. On the other hand, this was not normal.

"Woah, who is that?"

He almost chuckled as the child asked the very question that was on his and probably everyone else's mind. No, it wasn't a matter of who, but of what. For the figure that appeared on his screen was not a man, it was that of a monster; a Grimm. It's jet black body was lean and certainly held many human like qualities that would make you believe it was so. Sadly, the white bone-like structures that covered it like the armor of a knight betrayed its true nature. Or at least it should have.

The screams of the townsfolk as the invasion came could be heard throughout the video. The fear that they projected would attract Grimm for miles and as such it was not a surprise that this new Grimm appeared. It was what it did next that threw them both for such a loop. This knight-like Grimm did not attack the people of Soleil. No, instead it defended them. It attacked its fellow monsters with a sword of black and single handedly destroyed their forces.

"Well Peter, as our resident Grimm expert, what do you think?" Ozpin asked the very man that brought this video to their attention.

Peter Port was a somewhat portly man with an exuberant personality. His main focus both as a teacher and Huntsman was the study of Grimm. So when he discovered that there was a newly unidentified Grimm, well excited could not even begin to describe him. Apparently, he had been giving a lecture to the third years about Leviathans until a student asked to show him this video. Much like themselves, he was shocked and canceled classes for the remaining afternoon.

"Honestly, I'm not sure," Port replied reluctantly, "The video is rather poor in quality and loses track of the Knightstalker often. As such, I can not get a proper opinion of how this Grimm fights. Though I agree that its choice to defend humans is interesting. Is it the result of some new evolution amongst the beasts or has this one devoured so many humans that it developed a conscience?"

Port continued mutter about different theories as his two colleagues stared at him in bewilderment.

"I'm sorry," Goodwitch interrupted, "Knightstalker?"

The portly man seemed almost taken aback, "What? Well, we can't just keep calling it "The Grimm." It needs a name!"

The headmaster took a quick sip of his hot cocoa, "So you decided to name it the 'Knightstalker?' I must admit I was expecting something a little more grandiose."

Port hmphed in annoyance, "I, sadly enough, did not get to choose the name. Apparently, the people of Soleil were the ones to do so. Claiming that it was in thanks for all that it had done for them."

Ozpin and Glynda gave each other a brief look in what seemed almost like confusion and worry. From the sounds of it, this Grimm had been around for a while.

"Port," Ozpin further interrupted his colleague's grumblings, "How old is this video?"

"At least a few months," the professor confessed, "I'd say it came out in the later parts of the first semester."

Port immediately started typing on his scroll until several pictures appeared on Ozpin's monitors. All of them were obviously taken from a distance and as such didn't pick up on any great details. Yet, it was obviously the Knightstalker.

"These pictures show that the invasion was not the only time the beast has been active," Port lectured, "Apparently, the Knightstalker has a habit of patrolling the town and fighting off any other Grimm that happens to sneak in."

The headmaster's eyes narrowed as he saw images of the many fights that had occured. With this many attacks, you would think that the town would have called in for aid from the Huntsmen.

No….no they wouldn't. Huntsmen were trained to kill Grimm almost indiscriminately. If they felt indebted to this particular Grimm, then it wasn't a surprise that they would try to protect it.

"This Knightstalker is certainly an oddity," Goodwitch noted, "Perhaps we should send someone to investigate it?"

"AGREED!" Port yelled hastily, "And of course as a Grimm expert it is only natural that I volunteer my services."

The pompous attitude aside, Ozpin had to agree that Port's expertise could be useful in this kind of assignment. The only question was who should go with him. Missions like this required some level of care as if the town truly wanted this thing safe, then they may not want anyone with hostile intentions. There weren't many Huntsmen he could send in that case. Port was one of the few that would be willing to go near a Grimm in a non-elimination setting. Sadly, that meant excluding a large number third and fourth years as well. So, who should he send?

Then like lightning, it hit him. If there was one group that could get into that town with ease, then it was them.

"Glynda, please contact Teams RWBY and PVL," Ozpin ordered, "Let them know to come to my office. We have a new mission for them."

His two colleagues felt their jaws drop.

"Ozpin, you can't seriously be intending to send first years on a mission like this?" Goodwitch questioned.

"But I do," Ozpin grinned, "I'm hoping given their history that there should be little trouble getting information or at least a place to stay."

Port looked just as confused as the Deputy Headmistress, what history? As far as they knew none of the teams came from Soleil. Well, except for….

"Mr. Arc," Goodwitch gave a light growl.

"Yes, Mr. Arc," Ozpin confirmed.

Port sat uncomfortably near the two as the tension in the room seemed to grow heavier all of a sudden. Then again, this wasn't the first time that the two had gotten into an argument about the boy. He remembered Jaune Arc as a rather pleasant boy, perhaps not the brightest or most skilled, but he was willing to learn. That alone set him apart from others that felt that they were ready to take on everything. It was such a shame what had happened to the boy. Still, perhaps expulsion was better than what ever Glynda had planned for him.
