I do not own RWBY nor dothack Trilogy.

So there are some ideas swimming in my head, one of them is this, and since there are only few dothack crossover with RWBY so why not? At first i want to write a Hollow Knight x RWBY but since I am more familiar with the dothack trilogy i wrote this instead.

By the way Haseo x Alkaid best otp.

"Morning," normal speech.

"Yuri loves knives," thought.

"Hmp," Morganna Factors speech.

Story start.

Today was supposed to be a recreation day for the Xiao Long-Rose household. Ruby and Yang would visit auntie Chen at a town called Mulai and have a picnic with their father's there, or so they thought.

"Girls, I know I made a promise to go picnic today but the town mayor need my help. I can't refuse it since I have to repay a favor," said the promise breaker which is their father.

"But you promised!"

"I know Ruby. But I can't refuse this. You two can go with auntie Chen, I will join you later."

"Promise?"

"Promise."

"Pinky promise?"

"Pinky promise."

After both daughter and father sealed their promise, the father regards his eldest daughter with a strained smile, "Yang, don't cause any trouble and take care of your sister, okay?"

The slightly crestfallen Yang answered with her usual joyful tone, "You can count on me, Dad."

Satisfied, the father stand up and regards his sister, "Take care of them, Chen. Sorry you have to do this without me."

"Heh, don't worry bro. Your daughters will be fine with me," she said while patting his shoulder, "They'll definitely forget the promise breaker which is you."

"Ouch, that slightly hurts me. Well take care," and with that Taiyang Xiao Long start marching towards the mayor manor.

-o0o-

As Taiyang Xiao Long entered the manor, he can't help but think about the promise he had made with his daughters. Yes today should be a recreation day for his family, a day where he could make plentiful memories with them, but the mayor had to call in for his favor this very morning. Taiyang just hope it will end quickly so that he could spend the rest of the day with his family.

When Taiyang finally enters the mayor's study, he knew something was wrong because of the huntsman team standing in front of the mayor. "Ah, Taiyang! I'm happy you could come. Please come here."

Taiyang simply walk to the mayor's table and stand beside the huntsman team, gaining a look of recognition and respect from them. He was once a member team STRQ after all, "So what's the problem, Robert? I bet it's regarding Grimm since you already have huntsmen here."

"That's correct, Taiyang. There is a Grimm horde heading to this town from southwest, and of course I need huntsmen to purge those beasts. Since you're once part of team STRQ I humbly request your assistant in this extermination. My men and I shall participate if it's necessary."

A simple Grimm extermination, something that gives Taiyang a small relief. What could possibly go wrong? In his life as a huntsman, he never witnessed a large horde of Grimm in this area of Vale. Even if there is a larger horde, Robert would have called for more huntsmen.

"Mr. Speedwagon, may I ask a question?" asked one of the huntsmen in the room.

"Hm? Sure go ahead."

"Why are there two Behemoth type Bullhead in the town?"

The checkered high hat wearing mayor gave a hearty laugh at his question, "Oh, that? Well, you see we have a good relationship with the High Council. So with their help we could purchase some good quality construction materials and get delivered here."

"If that's the case sir, you can also request the council help regarding this Grimm matter, right?"

"I did young man, and they recommended your team! And since I like interactions, I chose to contact you myself. Well then enough said! I think it's time for Grimm cleaning!"

Taiyang can't be happier than that, the sooner it's done more time can be spend with his family. The huntsmen team seems to think the same, but for them it's more to the thrill of hunting the beast that plagued Remnant since the dawn of man; competing between themselves for who can slay more.

Sadly they are just one step away from exiting the room when the town bell rings aloud.

"Are the Grimm attacking?! Make haste men, we must protect the town!" and with that the huntsmen set off to purge the beast.

"Seeing them makes me feels nostalgic. I can only pray to the Brothers that they succeed in their task, but why am I feeling so unease today?" As if on cue the mayor's scroll rings in his pocket. He answer it, the call was from the guard he stationed on the wall. The mayor watched the video call and slowly terror began creeping up his face, "I-i-impossible! There are not that many last time we check!" on his screen a large horde of Grimm can be seen, so large that it looks like a sea of darkness pouring from the forest.

The mayor thought again that it was impossible, but then he saw them. Two Grimms that shouldn't be in a forest region; two crab-like Grimms; the Cornerstone, with their unique ability: illusion. With those two on their ranks it was possible to hide an army this large from the naked eyes.

The Grimm has learned how to make a perfect ambush on a broad daylight.

Ruby Rose was terrified. Earlier this day she got separated from auntie Chen and Yang, a problem she could solve by asking people around. But now all around her was monster. Creatures of darkness whose only desire is to have a taste of her flesh, and so she did something every terrified child would do, she hides.

She crawled inside a box; she stayed still, terror clinging on her mind. In this cramped space she can hear everything, from the Grimm's savage roar to the desperate plea of the townsfolk. She was terrified, she doesn't want to be here, and she doesn't want to die.

CRUNCH*

She can hear it; someone has been eaten beside her. She can feel it, whenever the Grimm chewed on its prey Ruby can feel the breath of the Grimm behind her ears.

And then she began hyperventilating.

Old memories surface and Ruby saw herself sat in a forest. It was only herself and her precious cloak. For a moment she was happy. She thought she had lost her cloak in the chaos before. Sadly her happiness didn't last long.

From every corner of the dark she saw them, the glowing crimson eyes of the Grimm, gazing towards her; towards their prey.

Terrifying.

"Yang… daddy… uncle Qrow… mommy…"

"……..save me…."

The two Bullheads had left the town just now. Those who survived are lucky; they are no aerial Grimm in sight. Many rejoice, but many also mourn. Inside one of the Bullhead Taiyang Xiao Long is panicking. Left and right he checked but Chen and his daughters are not there.

He keeps searching, ignoring the survivors he bumped, his family comes first. Then he spotted them, hurdled at a corner of the ship, and he hurriedly—desperately—walked towards them. When he was close enough to them he noticed something, there are only Yang clutching to Ruby's cloak with Chen hugging her. When Chen lifted her head Taiyang asked the dreaded question, "Ruby…?"

Chen shook her head.

Taiyang wailed in despair.

-o0o-

Little Ruby curled into a ball, hoping the creatures of darkness to vanish in doing so. They did vanish though; when those red eyes are getting closer Ruby was awoken by a Beowolf breaking the crate where she hides.

Eyes open wide, she saw everything around her. The blood; the mangled corpses; all of them are surrounding her, but most importantly she was surrounded by Grimm.

This is the end, or so she thought.

A blinding light suddenly appeared out of nowhere and a mighty voice can be heard, "Ruby Rose, I am Skeith 'The Terror of Death', from today forth you shall be my vessel," and Ruby Rose was conscious no more.
