A.N...…hello guys, this is my first fanfiction . Let's see how I do.

With RWBY, I always loved how they played with and used references from fairytales, legends and common tropes. And also, JNPR. I love those guys.

So here is my AU on a Remnant where the legends are the themes, rather than fairytales. I had to completely reboot canon on several things, but it would be clear if read. I hope this trailer pleases you! There's more coming if this works out!

WHITE

Quis custodiet ipsos custodes?

The city was a ruined, ugly wreck of a once beautiful oasis. Half torn down skeletons were all that remained of the houses. Torn wrecks were all that remained of vehicles on the torn streets. The corpses had turned to dust years ago. Not even memories remained of the life, death, achievements and actions of the people who called this ghost city home merely ten years ago. Only the beasts that killed the city still walked.

And now they sensed despair, anger, dismay, fear. Food.

A single man, not aged by the look of it, but tired in a sense separated from the physical, wandered the ruined streets with no purpose. A white cloak covered a tall, lean frame. He was gazing at the ruined city like he could see something more than the ruins. There was no menace to him, no danger, no fear.

The Grimm never hesitated for a moment.

A rain of Beowolves fell upon him, maws open and murder in their red eyes. The boy (for he couldn't be even twenty) merely gave them a lifeless look.

And then he moved.

A silver sword swept through the air, cutting the first five with the sheer force of it's swing. The next three changed direction to accommodate the blinding speed. But if they were as fast as a whip, the Knight was as fast as lightning. He stabbed the first in front of him in the neck and pulled back just in time to counter a claw that bounced off his shield. With the momentum, the boy kicked himself off the next into a graceful aerial spin, stabbing his sword in the neck joint of the last. He stepped over it's dissolving corpse and watched the massive wave that prepared itself. More and stronger would come. But for now, this would be all. The monsters roared in sheer bloodlust and hatred at his existence.

They never even got the chance to attack. The boy launched himself at the entire swarm faster than the eye could see. He bisected the first Beowolf in half, and then spun on his heel like a dancer to slam his shield on the next. The corpse flew to break the formation of the next wave even as he skidded to the middle of the fray. His sword sang through the air, once twice, many dozens of times as he danced on his toes to duck, dodge, sidestep, roll over and under the blows of his mindless opponents, taking one with each slash until none but him remained. A massive Ursa stepped forward, and was cut into half. A larger Alpha pounced in him, and was killed via a shield to the face that shattered it's head. They came to kill him in droves, and his simple, unadorned strikes felled them in speeds exceeding the speed of sound. And with a final smash of his shield to the ground, he unleashed a ripple of light and power that ripped the very street apart, killing the dense swarm of Beowolves swarming him in one blow. The boy stood triumphant before the decomposing corpses of his would be predators.

Then a building shattered as a giant parody of an ape emerged. Beringel.

If the presence of the Elder Grimm frightened him, no indication appeared. He merely tensed his shield as the Beringel jumped onto him, it's massive arms coming down in a two handed smash. Quick as lightning, he rolled under it's guard, supporting his weight on his shield to the ground, before the monster could connect . The shockwave carried him free of the Grimm as he rolled onto his feet in a smooth motion. Then he attacked.

Even as the Beringel reared itself to see where it's prey had disappeared, his sword slid under its guard to stab it into the chest…

And then the beast picked the hapless human up and threw him into the air, punching him through the air into an old Church, as if the injury was of no consequence. Assured of victory, it reared and roared a challenge to the heavens, smashing it's giant fists onto it's chest in victory, in a mockery of the animal it resembled. A premature celebration.

For the next moment, the building collapsed as if torn from the inside. The Grimm marshalled it's limited intellect to glare right as the boy emerged from the building, a white light shining like the moon around him, shielding him from the collapsing stone structure even as it cracked the ground and filled the dark night with it's sheer brilliance.

The Beringel screamed again as it attacked. But this time, the human didn't dodge like before. Instead, he raised his shield up and smashed the ape in the chest before it's hit could connect. This time, he didn't evade. The silver sword stabbed the beast again, then again and again, connecting seemingly hundreds of times in the span of a second. The Beringel swept it's hand in desperation, trying to bat away the human. But the man simply crouched to the floor to avoid the hit and jumped up again in a single smooth motion, using his sword hand as a spring like a professional dancer to jump up. Then he attacked in fury, his shield batting away the half formed punch of his opponent and shearing off it's arm at the shoulder with a wave of superhot Aura. Then with one final blow and a scream, Jaune Arc sliced the Beringel into two at it's waist.

As he witnessed the body dissolving in silence, a sound emerged from his scroll. He opened it to see a message from his alleged subordinate.

"In case you're functional, reply immediately.-WS"

Jaune Arc smiled to himself even as he sent the white haired Specialist a reply asking her not to worry. The Grimm roared in the distance, as he turned to leave with only a single backward glance. Winter would despise any tardiness, and the main threat was neutralized anyway.

He had school to prepare for.

Only two months before Beacon.
