They go to liblerium to learn some history to the Imperium and the Galaxy and it's races.

30 minutes later
the Imperials,JSDF the Girls were shaken in fear They have also an elf but they Calling them Eldar similar but taller and more graceful and more powerful able to match the space marine in combat,Next was the ork violence race, next was the Necrons the girls and the imperial have panic again a living metal with no soul all they want is to reclaim their ancient empire and far more advance than the eldar, next was the tau a blue and short creature and far more merciful, next was the tyranids a numberless horde

  the Falmatrs and JSDF were having a thought "For 10,000 years they survived in all fronts which is impossible" the liblarian have even explained to them they are allies with Eldar,Tau,And Necrons who's appearance is a skeleton even Rory mistaken them to be Hardy's minion regardless for what they explained to her.  

  The 4 nations have in peace and they have a only small battles until the Gate came, The 3 other nations also wanted to join the fray making the Imperials nervous  

  After they are going to Planet calth for some history before they need to go to a ship when got to the space the Imperials,JSDF eyed wide like saucers they saw all the ship in all shape and size and space station almost the size of moon "Some of this ship are large as the capital others were enormous" said Pina clearly she could feel to be threatened even they are not  

  Even for the JSDF in terms of air superiority the Ultramarines have the upperhand "Which were going to board?" ask itami "There" said Ronan all of them followed his eyes they saw a 26Km ship with raw upon raw of guns   

  "That's the Macragge's honor the Ultramarines flagship" said Ronan "Why would we board your flagship? isn't it to be very important rather than a convey?' said hamilton still shaking in fear "Lord Guilliman's orders was to board our Flagship making the pirates and raiders to discourage to attack us and only a fool or have a death wish would try to attack this ship" replied Ronan  

  After that they board the Macragge's Honor and what they saw inside are Vehicles,tanks and aircrafts and tens of thousands of space marine this is likely a safety to the ship, there are even human crews and somelike cyborg  

"What are those?" asked shino

"Those are servitors. people that have been cybernitically modified to do a manual labor and follow orders without quistion(he look to their faces) and do not worry they are only criminals like murderers,rapers etc other were dead people and the other were clone" said Ronan

"Led them to the guest room" said Ronan as he ordered ligiones serf

the servant have led them to the guest room

after that they are given a room which is sight to behold there is a 10 king size bed and a view the endless space "Make yourselves comfortable and Lord Primarch Guilliman will also board which he will also help to explained the history of the Imperium from 10,000 years of existence" the servant said as he walk out

"This is comfortable" said Rory as she is lying in the bed

"I never dream that we will going to outer space let alone to travel to another planet" said Itami.

"I never imagined they could reach this level are they mocking the gods?" said Pina

"No" said a voice they look behind and they saw Ronan enter

"We never mock the gods it is they who allow us to be such an advance civilization and i'll explain to you our brief history since we will arrived in 3 hours in calth" said Ronan

for 3 hours Ronan have told the story from the rise of the Emperor in Terra or earth as they calling it during the ancient time he led a crusade which will unite mankind and during those years Humanity was a xenophobic until a great war came and he will tell it for another time

Hanger deck
They move to the hanger which there is a shuttle ready for them after 10 minutes they decend to the planet

Calth

"It's almost like Earth" comment shino

Like Macragge they have also a fleet of ships and space station defend the planet

as they Decent to the planet the shuttle's ramp open revealing a beautiful city Just like Macragge but not grand as macragge 

"it's beautiful" commented Hamilton

"come on we're going to learn some history of the imperim" said Ronan. 

He explained how calth been colonize and how they broth it to imperial compliance 

"Then an invasion came" He stop dead silence came 

"An Invation? why is that...This world have heavily defended by your floating cathedrals" said Boze 

"The enemy we face is no mortal creature" said Ronan

"What can possibly be that a powerful enemy that can match you" said Pina she do not why she ask maybe she needed to know this enemy of their's and try to convince them to their side and fight the Imperium. She already that the Imperium has Many enemies and they are all destroyed.

How wrong her thought even if she mange to contact their enemy only death and destruction will come to them and if the Imperium knows this and their allies the sandera is done and possibly their world but before they going to do that evacuation first must me prioritize

"Demons" Then silence came

Luckily the Dark gods are Dead

"De-Demons?" asked the Imperials in unison all of them are shaking "What kind of war did they ever part of?" Pina Thought 

"Demons are the servants of the dark gods of chaos they are 4 powerful beings that resides in the Warp i believe during the ancient times of Earth it was called "Hell" he said 

Shino, tomita and the imperials are shock they did not hear it during the Diet.

"Wa-wait let me get this straight are you saying that the warp is hell as in the real "Hell"were all bad people go?" Shino ask trying to understand for what he said

"Yes" 

"And Demons as in Christian demons?" tomita asked

"I do not know this christian religion you speak of(But they will not tell their allies from another galaxy he knows the UNSC religion) but the demons are real" he Replied

"So could tell your story then?" Pina asked

Pina was now very nervous whatever these demons that could make the Imperium and it's allies to band together they must powerful

"Alright then i will tell you" he said

Then Rory begun to have vision a past of these city.

________________________________________________________________________________

Rory being a demigoddess granted some unique skills and abilities. And one was able to be  able to see things may have been like back then. It was something ties to people, place and things were where value great. Spirits tented to be that way.

She walks around the street flames and bodies she saw them men,woman and children all were butchered even space marine she is surprise to see a space marine dead leaning in the car blood all over it's body. they are at least a thousand bodies of the space marines

this enemy is surely they are very powerful that can beat and kill a space marine

She still walks around the street "So much death" she thought

And not for long she saw their enemies.

M31 Battle of Calth(and no traitors just demons)

She back away just the sight of it. it holding the skull of a space marine

she could sworn this space marine are smaller than the ones she saw

These creature have skin red as blood she could feel these demon are really an immortal creature.

In all her years she never felt fear of such creature

She saw flames around the city

Then saw a woman holding a baby she followed them.

"My baby" as she run

 She followed she tried to help but she can't. As another demon appear 

Another class of demon appear while the red one attacks the soldiers this one are attacking anything in their sight.

She saw them how they cleave a man in half.

As they are near to the woman

She heard Gunshot as the demon's head explode

She saw the Space marines in huge armor that they called it "Terminator armor"

Don't let them hurt my baby" as she run pass by the Space marines

"Your fight is with me demon" he said as they lumbered towards the demons firings it's combi bolter 

Each shots were perfect they hit their target

They walk to them fearlessly "But how can they defeat them all?"  Another thought to herself she can see they walk without fear  through the demons the demons begun to attack them in numberless horde.

She saw the metal clashing against metal 

"Do not let them pass!" shout the sargent terminator 

During the siege italica they never fight serious but this one they clearly given it all to the equal opponent and she is still wondering how strong they were.

They are not just defended the city they protecting the innocent Rory was still wondering such a powerful warrior like them protecting an innocent people.

Her vision begun to shift it was now night.

She saw the Ultramarines preparing for a defense In front have a large shield

 she saw then a DreadnoughtWalking pass 

 "WHAT IS THIS HERESY!!!!" he shout from his vox clearly that he is not please to see this city burn

He fired his plasma weapon to the demon along with other Space marines they too fired their weapon others were using sword.

Then again demon against demigod.

And that her vision ended

________________________________________________________________________________

"And that's what happened" said Ronan

"It must be horrible" said Hamilton

"But in the End we won the battle...But we lost contact to the imperium" said Ronan "But we shall go now to terra the Empress is still waiting for you"

All of them have returned to the Macragge's Honor to travel Terra throneworld of the Imperium.
