Falmart

As The Legions or chunks of it gathered in the chamber with The Primarchs Infront of them waiting for orders.

"

The Voices of the Astartes Were not of each individual but as one. Their voices boomed throughout the palace and it even reached outside the palace.

The Emperor for the first time in over 10 millennia was leading a crusade but this time Humanity isn't alone they were joined by The Eldar in this crusade.

A BattleFleet was Formed above the skies of Holy Terra Preparing to Warp Jump(Since they haven't built a webway gate to falmart yet they're traveling the old fashioned way)With Each legion Carrying a transponder that emits a Signal only a Eldar or human Star ship being able to detect it, They could theoretically Jump to any part of the universe (and/or other dimensions) with this technique.

It has been decided that only half the legions summoned will only go through the gate. The other half will wait until the webway is Finished The First ones who will go through are:

Lion El' Johnson and his Dark AngelsMagnus The Red and his Masters Of Change Alpharius and Omegon and their Alpha Legion The Imperial Fists Led By Rogal Dorn The White Scars Led by Jaghatai Khan (Bikes included)5 Death Korps Of Krieg Regiments2 Cadian Regiments 2 Catachan Jungle Fighter Regiments One( And it will stay that way) Sly Marbo  Over 100 baneblades 2000 leman Russ Tanks (Aerial Forces will come with the BattleFleet)The Sisters of Battle The Emperor Leading his Golden Bois

Roboute Leads the Imperium for a while and the ones who'll help him lead are:Corvus,Leman and Vulkan and their legions

The Reinforcements:

The Black Templars The Lamenters(Needed to join because they always got their Asses kicked)The Charcadons The Raptors(The Chapter not the Failed Project)Iron Fists Led by Skost Ferrus Mannus A few million Guards men (From various Regiments),Over ten thousand Tanks(assorted)

"My Lord Isn't this a bit overkill?"Said Kitten

"Well there are 20,000 astartes Sent to this... falmart"

"Oh,Okay then,So the Imperium of Man is just technically Married to The Eldar?"

_______________________________Troops have amassed on the Imperium's side of the Gate and are preparing to go through:

The Plan Is thatThe White Scars Will go first and secure exactly 3 kilometers of land and lock it down and then Kriegsmen and Imperial Fists will go through and create fortifications and DefencesAfter that The Rest will go through,With The Alpha Legion and Eldar creating a Spy Network and monitor the "Saderan Empire" and troop movements. With knowledge Received from one of the Captured Commanders Called "Count Formal" they knew exactly how many Towns were under The saderans and how big is their empire how much manpower they had and how strong is their empire and then there's mythical creatures....

Vulkan Wanted to boop some snoots,So with Vulkan Asking the emperor A LOT OF TIMES,The Emperor Caved and allowed a single Chapter of the salamanders to join.(I forgot about this but all the chapters were turned into legions they are directly commanded by A primarch depending on their Mother Legion)

The Imperial Senate was a mess, Emperor Augustus Molt couldn't believe it their best and most capable commanders were defeated in a few minutes and Rumors about the world Beyond the Gate,Giants Made of Metal guarding the entrance and Giants Made of Gold protecting Their presumed deity a giant Man in Golden armor, And As much gold as far as the  eye can see,half of The senate wanted Wanted to send more men in hopes of overwhelming this "Golden Realm of Giants" after all they are the most Powerful Empire to grace this world while the other half wanted to sue for peace,Thinking they could be reasoned with,Heck Emperor Augustus' Children were even split on this matter,His second born was Siding with The Pro-Peace Faction, And his firstborn was siding with The Pro-War faction thinking they can be defeated with numbers alone.

Prince Diabo(Second born)is currently in a heated debate against Prince Zorzal(Firstborn)

Zorzal:WITH A WAR OF ATTRITION WE CAN WIN ANYTHING!

Diabo:LIKE YOUR RECENT "VICTORY" AGAINST THE WARRIOR BUNNIES?! WE LOST OVER A HUNDRED KNIGHTS AND THOUSANDS OF LEGIONNAIRES THAT WAS DESTINED FOR SOMETHING GREATER!

Zorzal:A VICTORY IS A VICTORY!

Diabo:IN MY EYES WE STILL LOST THOUSANDS OF MEN!

Zorzal:THEY KNEW WHAT THEY WERE GETTING INTO!

Augustus:ENOUGH! Let's say we do this at a vote?

The Senate then spoke among themselves and nodded at their emperor.

Augustus:Peace? Raise your hands.

Peace-31

Augustus:War?

War-69

Augustus:...nice...

Augustus:We Will Declare War!

Zorzal with a smug face looks at his defeated brother

Zorzal:The Senate has spoken,Brother.

Then a tired messenger runs to the emperor and whispered something in his ear.

Augustus:Hmm... Interesting.Thank you,Now BEGONE!

The Senate looks at the emperor worried about the news that has been brought forth...

Augustus:The Other Worlders Has Taken Alnus Hill.Call upon our vassals,We shall remove their armies from the picture to make sure we won't get a rebellion.

///////////////////_________\\\\\\\\\\\\\\\\\\\\

It's been a few months since The  Order was given to the vassals they have amassed Over 200,000 Men combined and their own intelligence says that the Other Worlders had 20,000 personnel on that hill. So they were going to send 30,000 thousand men in hopes of a swift and easy victory with numbers. OH BOY THEY WERE WRONG

1st day of The so called "siege"

Falmartian Forces were decimated before even getting close Reports say of "High Level Explosive Magic" So the Falmartians Thought these were mages so they called for master Mages

2nd day of the siegeMages are now evenly distributed throughout the divisions and in the late afternoon The tried to charge up the hill but like the others before them but like them they were quickly decimated

Duke Bristol:2 Days.We lost over 60,000 men in two days we didn't even lay a scratch on their walls.

King Duran:Perhaps a night raid shall suffice?

It did not

The Vassals With all of their remaining forces tried to take alnus hill at night,they were hit with artillery,las fire and If they somehow managed to survive that Space Marines Charged at them cutting through their men,like a hot knife through butter,Then a whistle was heard Kriegsmen charge out of the trenches and killed every straggler they could encounter. That 'Battle' was forever known as The Massacre of Alnus Hill.\\\\\\\\\\\\\\\\\____________/////////////////

The Emprah and His Companions were in a Modified land raider specifically for him He wanted to Study this new world alongside his Son and Fellow Nerd Magnus The Red. The Masters Of change also joined in.

As they were wandering the country side they found a plume of smoke so they headed towards it.

They arrived in a Village that was recently burned to the ground and bodies littered the ground They Were Completely Unfazed.

They Found One survivor in a well And Using The For- I Mean Psychic Abilities to lift her up and upon closer inspection. She had Elven ears and she woke up Afraid clearly. Then they took Off their helmets she was a little at ease, Then The Emperor Stepped Forward and Kneeled to make eye contact,

The Elf Seemed a little bit confused At what he said,To her it was Gibberish.

Then His eyes started to glow his beautiful Golden Eyes.(Author's Note:I'm doing this of my own free will and there is totally not a Horny Sister Of Battle Pointing a bolter at the back of my head.Please Help)

He Spoke again

"Y-yes" said the Elf

"A-A G-great F-fire D-Dragon."

"North East"

"It is my Honor,Sir?"

"Tuka Luna Marceau."

She agrees and follows the custodian

"Are You Sure about this father?"Asks Magnus

"You're gonna Impregnate her aren't you?"

"You're not tricking anyone. And I'm gonna make sure No woman in a 3 meter radius is gonna get near you. Including A Sister of Battle."
