XenoBlaze:Hello everyone.

Welcome to my first fanfic.

Ruby:Aren't you excited?

XenoBlaze:Very. This story has been on my mind alot.

It takes two of my favorite shows and puts them in one.

I just hate it took so long to get started.

Ruby:You were just being lazy, weren't you?

XenoBlaze:...Do you want your cookies or what?

Ruby:Im sorry! Im sorry!

XenoBlaze:Anyway, the prologue is already up.

I originally wanted to make it one chapter. But things didn't work out well.

Ruby:So now you have THREE chapters!

XenoBlaze:Right.

Now, get ready for RWBY Extella.

But first...

Ruby:Oh right.

XenoBlaze does not own RWBY or the Fate series. All rights go to their rightful owners.

Now about those cookies.

XenoBlaze:Yeah, they're right...

Hey, were they go?

Nora:*Munch* *Munch* *Munch*

Ruby:NORA!

XenoBlaze:How did she get in here?!

AN:Thank you yogwind for the suggestions. Everyone please check out the Fate/RWBY crossover A New Dream.

Also I'm not very good at fight scenes, so please be nice.


Prologue Arc Extella 0-Scholar of the Umbral Star Returns


The Moon Cell. A spiritron computer, which exists on the moon.

Over time, the planet known as Earth has become ravaged and lifeless.

In a last dich effort to keep the prosperity of the human race from dying out, man relocated to the moon.

Inside the Moon Cell, humans and NPC live in a spiritron-constructed virtual world known as SERAPH.

The Moon Cell is always learning from the knowledge of Earth.

One event stands out above all others. The Holy Grail War. A competition that decides the ownership of the Holy Grail through intense battle royale.

While there have been many conflicts over supposed Holy Grails in the past, this term refers to those specifically based around Masters. 7 proficient magi who summon Servants, Heroic Spirits brought forth as familiars.

They meet in battle until only one pair is left to claim the Holy Grail.

The same is said on the moon.

Years ago, a human and her Servant conquered the Moon Cell and obtained the authority of the Moon Cell Core. The Regalia.

The symbol of victory and sovereignty in SERAPH.

However, the newly appointed sovereign had a much larger role. For a threat was fast approaching the moon.

The Umbral Star. Otherwise known as Velber.

An alien threat that appears within the Milky Way every 14,000 years.

The Umbral Star travels the galaxy, and when it detects sentient life it creates Anti-Cells and sends them to destroy and devour them.

It destroys all intelligent civilizations in its path, and in doing so, it consumes all digital data within reach.

Along with her Servant, the sovereign was able to topple the Umbral Stars apostle as well as Velber.

...And thoroughly ruining my plans.

However, I am a patient man. And they only managed to destroy a fragment of the Umbral Star.

Velber still awaits. And I now have the means the remove those obstacles.

Hakuno Kishinami. You and your Servant thought you were rid of me. Think again.


- Mare Aurum's palace/Nero's territory at night-

A woman wearing a white dress wakes up with a start.

As she sits up, she realizes that the events she experienced were a dream. A nightmare.

This woman is SERAPH's sovereign. Hakuno Kishinami.

Hakuno:Ugh. Not again.

Hakuno looks around and her eyes fall to a woman in bed with her.

She wears a red dress and has blond hair in a bun tied with a red ribbon.

Even when sleeping, Hakuno can imagine the woman's green eyes. Looking at her with confidence and warmth.

The woman opens her eyes and stares at Hakuno.

?:Soshayo?(Player)

Hakuno:Sorry.

Did I wake you Saber?

?:She wasn't the only one.

Hakuno and Saber turn to see another woman and a young girl in bed with them.

The woman wears a blue chinese dress and has pink hair and golden eyes.

Her most noticeable features are her two orange fox ears and tail.

The little girl is dark skinned with red eyes and wears a white dress.

Hakuno:Caster. Altera.

Caster:You were moaning in your sleep Goshujin-sama.(Beloved husband)

Altera:Master. Are you alright?

Hakuno stays silent as she looks down.

Caster:It was that dream again, wasn't it?

Hakuno:...Yes.

A few months ago, Saber, Caster and all the Servants of SERAPH banded together to thwart a mad man known as Archimedes.

At first he was the system administrator of SERAPH. But after being corrupted by the Umbral Star, he tried to destroy SERAPH.

And used Altera to achieve his goal. By destroying all who stood in her way.

Saber was the one who struck Archimedes down, but Hakuno is still plagued by the events. More specifically, what COULD'VE happened.

Hakuno:I just can't help but think what would've happened if-

Hakuno is cut off as she feels someone's arms around her.

She turns to see Saber holding her.

Saber:Soshayo. Listen will to me.

You are still here. WE are still here.

Thinking about events that may have come will bring nothing but worry.

Hakuno relaxes as she feels more arms around her.

She looks to see Caster and Altera holding her.

Caster:Please do not worry yourself my dearest.

Tamamo feels sad when you're sad.

Altera:Master.

Its because of you that I'm here with you, Nero, Tamamo and everyone.

So please, don't be sad.

Hakuno closes her eyes as a small smile comes to her face.

Hakuno:Thank you.

All of you.

Sometimes I wonder what I did to get friends- a family like you.

But I'm glad your here with me.

Saber, Caster and Altera smile at Hakuno's words.

Tamamo then quickly ushers Hakuno back to bed.

Tamamo:Now, Now.

Back to bed Goshujin-sama.

And no more nightmares. Tamamo will chase them away.

Saber:Ha!

Sleeping next to a devious fox such as yourself encourages nightmares.

Truly, if she is to have a blissful sleep, she would do so in my humble embrace.

Caster:Mikon!

How dare you accuse me of such an act Baka Kotei?(Stupid Emperor)

Hakuno:Girls please.

Let's just go back to bed.

Saber, Caster & Altera:Hai.(Yes)

Sweet dreams Master.

And with that, the three Servants and their Master drift back to sleep.

Unaware they are being watched.

?:Sleep while you can.


The next day, Hakuno is seen setting in the throne room overlooking the state of SERAPH

Hakuno:Hmm.

Looks like things are going well.

Hakuno looks around and could not stop feeling alone.

Before, the Roman Capital was full of her trusted Servants.

But now...

Hakuno:(Its so lonely here.)

(Saber, Caster and Altera aside. There's no one else around.)

(Gawain, Cu Chulainn and Li Shuwen went out into the world to do their own thing.)

(Karna and Medusa are always busy and no one knows what happened to Li Bu.)

*Sigh*

I just hope their okay.

At least Archer is here.

(He still hasn't told me his True Name. Or anyone for that matter.)

Hakuno is interrupted from her thoughts as an alarm sounds.

Soon after Saber, Caster and Altera appear.

Saber:Soshayo!

What is happening?

Hakuno looks closely at the holographic screens.

Hakuno:It seems there's some kind of activity...at Zero Dark!?

Saber, Caster & Altera:What?!

Altera:But that's impossible. The Zero Dark is sealed.

That area can't be accessed without the Regalia.

Saber:Umu!

Altera speaks the truth. Yet these sensors say otherwise.

Caster:Is there a Servant causing trouble?

Hakuno:Rrg.

I can't identify what the problem is.

Whatever's going on there has a large concentration of mana.

Another alarm sounds.

The four saviors take another look at the screens.

Caster:Mikon!

The Moon Cell is detecting multiple Servants in that area.

Two of them are Top Servants.

Saber:Could it be that golden Archer causing trouble?

Caster looks at Saber with a slight glare.

Caster:Do not speak of THAT man.

Hakuno thinks for a few minutes before standing.

Hakuno:Archer!

In a flash of blue spirit particles, a man with silver eyes and white hair appears.

He wears a red coat with a black bodysuit.

This man is Archer. Also known as Nameless.

Archer:You called Master?

Hakuno:There's activity in the Zero Dark area.

We need to investigate.

Saber:Soshayo.

I will accompany you.

Caster:So will I.

Altera:Me too.

I know more about that area then the rest of you.

I lived there after all.

Saber, Caster and Hakuno look at Altera before reaching their decision.

Caster:Master.

Saber and myself will be more than enough to protect the both of you.

Saber:Umu.

Though she may be a child, Altera is still a Servant.

Hakuno:...Alright.

But don't strain yourself. Okay Altera?

Altera:Right.

Hakuno:Archer, please watch over things from here.

Archer:Normaly I would say to send someone else instead.

But seeing as were low on man power, there's no choice.

Watch yourselves out there.

Hakuno:Thank you Archer.

Hakuno gives Saber the Regalia then disappears in a flash of sprit particles and transfers to into the ring.

Hakuno:Let's go.


-Zero Dark-

The Zero Dark.

A desolate place of darkness. And former home/prison of Altera.

As the for saviors get closer to their destination, they begin to here sounds of combat.

Saber:It would seem that the Servant's we detected are fighting.

Caster:Who they are fighting is what I'm concerned about.

Before the group take another step, they are confronted by strange creatures.

These creature seem to resemble wolves.

Only their bodies are completely black and have white bone mask on their faces.

Their soulless red eyes seem to stare right into them.

Saber:What creatures are they?

Caster:I've never seen them before.

Altera-san?

Altera:I've never seen them before either.

But I can sense very intense negative emotions from them.

Hakuno:I've checked the Regalia. There's no record of them either.

The strange creatures roar at the Servants as the begin to attack.

Saber summons her sword while Caster assumes a stance.

Saber:Stay behind us Altera!

One of the dark wolves attacks Saber, but she sidesteps it then slashes the wolf with her sword.

The creature falls and seems to evaporate into black smoke.

Saber:How strange.

These creatures clearly aren't hostile programs.

A wolf attacks Caster, but she dodges it and kicks it away.

After that she uses a fire spell on the wolf and it instantly evaporates.

One by one the dark wolves attack but are met with the same fate.

Caster:They're quite tenacious. And annoying.

While Saber and Caster deal with the creatures, they don't seem to notice on creeping up behind them.

The wolf lunges but before it attacks, it is sliced in half.

Saber and Caster look to see Altera holding her own sword.

Saber:You have my thanks Altera.

Caster looks forward and sees that more creatures are converging to their location.

Caster:There seems to be no end to them.

Saber:Stand aside.

I shall use my Noble Phantasm-

Hakuno:Wait!

We don't know if there's something worse ahead.

Those other Servants must be fighting these creatures too.

Save your energy.

Saber:Then what do you suggest Soshayo?

Hakuno:Caster.

Can you freeze them?

Caster:Consider it done.

Caster focuses for a few seconds before channeling her magic into a freezing spell.

The spell quickly freezes the surrounding enemy's.

Hakuno:Saber.

Clear a path. Then we'll make a break for it.

Whatever created these things has to be up ahead. If we destroy it, they might disappear.

Saber, Caster & Altera:Understood.

Saber rushes through the frozen enemy's with flames surrounding her.

Caster and Altera follow her and head towards the source of these monsters.


As the four saviors reach the center of Zero Dark, they notices two things.

One:There are more creatures around.

Some of them look like older versions of them.

Two:There are in fact other Servants fighting the creatures. Some of them the saviors know.

One was a woman with long lavender hair wearing a sort of ninja outfit.

She has a visor covering her face and uses chain knives.

Another was a woman with blond hair and violet eyes.

She wears a violet dress with silver armor and uses a lance with a flag attached to it.

A rapier is seen on her left side.

The man of the group was destroying the creatures with a red spear.

The man had blue spikey hair and red eyes. He also wore a blue body suit.

The last was a woman who at first glance you would mistake as another Saber.

She wore a blue dress with white and gold here and there and silver armor.

She was blond tied in a bun and had green eyes.

In her hand seemed to be a weapon of some sort but is covered with wind, making it invisible.

Saber:What is this?

Hakuno:Ruler. Lancer. Rider.

Caster:What are you three doing here?

The new Servants continue to fight while addressing the saviors.

Lancer:Ah.

Late to the party ain't ya?

Ruler:However, your assistance is appreciated.

Altera however ignores the others and focuses on the woman in blue.

Saber notices Altera's gaze.

Saber:My god.

She looks like a doppelganger of me.

Altera:The blue Saber...

...Artoria Pendragon.

Caster:Mikon!

The King of Knights?! Here?!

Rider:She approach us and told us of a threat to SERAPH.

She was...very persuasive.

She made a hole large enough for us to enter the Zero Dark with her Noble Phantasm.

Lancer:When we got here, we ran into these guys.

Hakuno:But where did they come from?

Artoria:We don't know.

They seemed to appear out of nowhere.

?:Perhaps I can shed some light on this situation.

The four saviors freeze up at the sound of the voice.

Caster:Impossible.

Altera:It can't be.

Saber scowls as she recognizes the voice.

Saber:How can HE be here?

In a flash of yellow spirit particles a man appears.

He has brown spikey hair and has cold calculating black eyes.

He wears and outfit that would best describe him as a magician.

However his most unique features was that his left hand was purple with gold in places and there was a similar design on his neck as well.

From within the Regalia, Hakuno glares at the man with fear and rage.

Hakuno:How...

The man gives a cold smile.

Hakuno:How are you still alive...Archimedes?!

-To be continued-


AN2:Next two chapters of the prologue will be up shortly.
