Prologue: Unseen and Unheard


"Damn it, why the hell did our boss send only us to check out the sewers?" complained a young man.

"Because Jake, up top, people have been complaining about the quality of the water, Doc in town has reported in increase of people coming in with the shits, and don't get me on the smell everyone is talking about," his partner stated, irritated that he had to come down to work in the sewers on his day off.

"Well, that I get, but why us specifically Dave?" Jake asked.

"I don't know; maybe because everyone else had things that are more pressing?" Dave replied sarcastically.

The partner was right though; everyone else that could've done this job had other pressing concerns. Phil's and Linda's kids were sick with something that Doc couldn't or didn't know, Harper had sprained his ankle and somehow got it infected. Then you had Sean and Luke who up and left town like the Grimm were on their asses. But most odd was the sudden death of Bob and Cyan.

Bob was a retired huntsman, and while getting on in his years, was fit as a bull and able to send the Grimm running whenever they showed to attack the town. But a week ago, Bob's neighbors found Bob dead outside on his porch, beer bottle barely touched, the radio still on, with his throat slit open. Everyone in town had talked about how nothing could've snuck up on Bob, and they wondered who killed him.

But Cyan's death, well, it was kept quiet from the town's visitors, as it seemed Cyan had locked himself in his house, and more specifically his room, in a manner to keep whatever he had away from everyone else. Doc and the coroner had done an autopsy only to find that Cyan's internal organs had rotted away. More disturbing though were the frantic markings written in blood on the inside of Cyan's house with an ominous warning; They are everywhere! The walls have eyes, the shadows ears, and I can't sleep knowing that they are out there! To anyone who finds this-GET OUT! The End is Nigh!

"Well fine, but I don't have to like it," Jake said. "Anyway, where the hell do we go now?"

Dave took out a map and flashed a light onto a wall, looking at the symbol on the wall.

"Well, we are at the E4 Junction, and according to the control pumps, whatever is causing the sewer's issue is coming from the F5 Junction," Dave replied. "C'mon, we go straight ahead and take a left."

Jake and Dave headed toward the F5 junction when they both had to stop.

"God damn, what-cough- is that smell?" Dave asked. Jake stayed quiet, trying to keep the thick musky smell that reminded him of a dead cat carcass that was left to sit in still water from entering his mouth and causing him to gag. Quickly motioning to his partner to put on his respirator Dave put his on and pulled out a pistol they were given when inspecting these sewers.

While it was usually refugee for the homeless or stray cats and dogs, these sewers were often used by the smaller specimen of Grimm to move about without attracting too much attention. So, while most would scoff the use of a pistol for taking on Grimm, in the sewers, a pistol could reliably take on any Grimm that could be in the sewers.

The partner held his light under his pistol, scanning the tunnels. The young man had his light held a little above his head, and his right hand was next to his pistol. The two moved forward, and when they reached the junction, they paused, taking a breath to steady their nerves, and rounded the corner, light flashing down the tunnel.

What they were expecting neither knew, but seeing timber blocking the water grates wasn't it.

"God damn nerves, I wasn't expecting some wood to be the cause of this," Jake began to complain again. "I-"

Dave meanwhile tuned him out, confusion evident in his eyes. While the sewer system in town wasn't as elaborate as say Vale's, it was designed to handle a large volume of water due to it being on the coast. Thus, the grill grates on the surface were designed to keep large debris out, and sequential filters and pipes would sort out debris until only clear, if unfiltered, water came through. This also applied to the waste disposal in the city. So finding large pieces of timber meant someone had deliberately brought them down and were using them to block this integrate.

But why? It made no sense from his perspective. No one benefitted from messing with the sewer systems; it caused diseases, hampered with recovery efforts if a major storm hit, and in general was a nightmare to fix.

"Hey Dave," Jake drew his attention back to reality. "What are we going to do about this timber; it's too heavy for us to move by ourselves."

"Probably go back to the surface and-"

SKREECH!

Dave and Jake turned away from the timber as the horrible scratching noise of chalk on concrete permeated through the tunnels.

"What the fuck was that?" Jake whispered as he pulled out his pistol. Dave didn't respond, but he too began to aim his pistol to where the sound came from. It wasn't far off, and now he was paying more attention, he could hear the shuffling of feet approaching. Whatever it was, it was numerous, and coming closer.

"We need to get out of here," Dave whispered to Jake, who nodded quickly. They turned and began to run, but whatever had caused the scratching noise was coming, and faster. They knew this as the horrible musky smell that caused their earlier paranoia was becoming thicker and penetrating their respirators. And as Dave listened closer, the noise had become like the skittering of rats.

He and Jake turned at the F6 junction and begun heading to the A6 junction, the plan being to get to the ladder at the A6 Junction and get to the surface and report the problem.

As they passed the D6 junction Dave, with his heart pounding in his ear, was about to look behind him with Jake spoke.

"Hey, the noise and smell is gone." Dave frowned before stopping in his step, and listened closely. Sure enough, the smell of rotting dead cat wasn't as thick, and the skittering noise wasn't prevalent. "You thin-"

Before Jake could finish his question, Dave watched in mute horror as a sickly green bullet shot down the tunnel and blasted Jake's skull to pieces. Dave's eyes widen as his partner's blood splattered onto him, and he watched as the skin where the bullet had hit began to mutate to something unnatural.

"What the-" Something caused the hair on Dave's neck to stand on end, and he pointed the flashlight down towards where the ladder should've been. Instead of being able to see the ladder, his light barely made it to the C6 junction, but it illuminated beady red eyes that stared at him. Swinging the light towards the other tunnels at the junction, Dave could barely withhold a whimper as more beady red eyes stared at him.

"Not like this!" Dave shouted as he began to fire blindly down the tunnel, and soon the noise of skittering claws, followed by the screams of a dying man permeated throughout the sewer tunnels, but alas, no one on the surface could hear Dave's screams.


It was two days later when sewer workers and an accompanying huntsman found the blood of Dave and Jake, the only personal effects being their company flashlight and pistols. Thus a funeral was held at the town's cemetery, with the church bell rung thirteen times. Everyone in the town was somber, as yet another pair of their citizens were dead without any clue as to who killed them.

But as the sun set after the funeral, a comet with twin tails raced across the night sky, being witnessed by several key people, most not knowing it was marking the beginning of a new era for Remnant. Alas, one did know, and as they gazed upon the comet, they wondered whether it was a sign of peace or of war.


Author's Note: Damn you TheMightyJingles! I was perfectly fine with not being into Age of Sigmar, but nooo, you had to do a casual Saturday featuring Total War: Warhammer 2. And now that I engrossed myself into the lore of the faction that was mentioned in your video, I've become invested in it, yes-yes!

But in all fairness, how could I not, I've been looking to do a Warhammer/RWBY Crossover for a while now, but it never worked, because I was trying to keep it to Warhammer 40k. While I love 40k/RWBY a lot, especially if they involve the Death Korp of Krieg, I could never get it to work for myself; the lore of 40k and the technology breaks RWY's lore and powers by an unfair margin. But Age of Sigmar, or Fantasy if you hate AoS, it's not so bad. And actually, it's a lot more fun, as you can do crazy things that don't seem as out of place as 40k does in RWBY.

However, I know you wonder what the premise of the story is; and truth be told, I got a rough outline complete, I have envisioned several key events pretty damn well, but how much of a crossover it will be is still up in the air. I know initially what is going to be planned, but once we get past RWBY season 3, things are going off the rails, and I need to plan for them more in depth before I can give you guys a solid answer.

But initially, it's going to involve an OC that is a child of one of RWBY's main character that ends up back on Remnant after their parent ended up in the Old World of AoS. The how and why aren't completely locked in, but it'll probably involve the warp, maybe even the Great Vortex that is supposed to appear in Total War: Warhammer 2.

Now, as to what the fuck happened in this chapter, let me just say that I'm being intentionally vague to keep the suspense of the reveal up. If you know your Fantasy/AoS lore, you know what killed poor Jake and Dave. But you'll see in future chapters the culprit in greater detail.

Now this is where I leave you, but I expect to get the next chapter out in a couple of days as this idea is really addictive to me, and it compels me to write more and more. Until the next chapter, please read, review, follow, and favorite, and I'll catch you guys next time.
