June 6th 1900 Brandenburg

In the Wolff Family Estate in Brandedburg the wife of Erik Wolff, Samantha Wolff, was giving birth to their Child.

When the Doctor along with his assistant came out of the room after some minutes, Erik jumped from his seat and walked to the Doctor.

"How's the Situation Doctor?" Erik asked the Doctor the Doctor had long dark blue hair and Dark blue eyes.

"Well Herr Wolff, Your wife is doing very well." Said the Doctor, slightly reliving the man but he was also concerned about the child.

"Well congratulations are in order, your wife has given birth to a healthy baby girl." Said the Doctor with an upbeat tone as he opened the room's door revealing Samantha holding a bundle of a child.

"Shh, She's asleep." Said Samantha as she looked at her husband and then pulled the cover to show Dark golden blonde hair, and as the girl yawned and opened her eyes to reveal eyes so red they'd make rubies left wanting.

"I have a Feeling that she'll make great things one day." Thought the Doctor.

"So what should we name her Erik?" Samantha asked her husband, as he walked towards them. "I Think we should name her Adelheid." Said Erik

18 Years later

In the Last moments of the Great War Adelheid Wolff had grown up ever since she joined the Heer when the War began sneaking her way into it, surviving the Trenches the Gas attacks, and in the end she always seemed to come up on top earning the Praise of the Kaiser himself when she became 17 years old, and now here she found herself leading a squad of soldiers of the new Stormtrooper Corps, She then turned to her Soldiers all of them seemed tired, tired of the war, tired of the Non stop combat, tired of the Sleepless nights, they were tired and beaten, but they still held as the fatherland depended on them. And Adelheid herself deep down she began to loath the High command, that they send these men and boys, these fathers and sons into what is a lost war.

"Soldiers! Do not think about hunger and exhaustion only think about the Great German Empire! The Prussian People expect a Peerless Victory! Let fate guide you may the spirit of the Prussian people be with you! For Germany, For the Empire, For the Kaiser and our people!" With that Speech and thanks to her charisma the spirits of the Battered Soldiers were lifted to a new height, and once they all heard the whistle blowing she looked at her Soldier, her children, one more. 

"Now Soldier let's Get out there and Destroy these Cursed Frenchmen!" Said the Adelheid as all them Cheered and charged up the no man's land and attacked the French Trenches.

Berlin 1939

Adelheid was accompanying her boss one Reinhard Tristan Eugen Heydrich, he was a Blond man with short hair, dark blue eyes ,he was dressed in black SS uniform much like her but tailored for male ware. Now ever since the Lost of the war 21 years ago Adelheid's life hadn't been easy she had been plagued by strange dreams a boy with rust red hair he had an aura that seemed to speak of a martyr's complex fueled by Survivors Guilt and he was facing against another man this one was a Blond man with eyes much like her's but they were slitted much like a cat's own eyes this one had an aura of Arrogance and Self-Confidence fueled by Selfishness. Her Parents were murdered by someone they once had called a family friend. 

And then 1920 when she joined the Freikorps she met a 15 year old boy named Reinhard Heydrich which she took as her protégé, but before they met Adelheid had used what inheritance her parents had left her to open a nursing home for the crippled soldiers of the war.
Some time ago when the National Socialist party took power in 33 the SA and the SS attempted to close her Nursing home for the crippled soldiers, but Adelheid being regarded as a heroine to the German people especially among the veterans and the Freikorps, they were forced to back off as not to ruin the Image by closing an Institution found by the Golden Valkyrie, and it was well known information that despite her age Adelheid viewed the Soldiers as her children.   

This event caused Adelheid to have a Hatred of Himmler and his bootlickers.

Now skip 19 years later she's now Reinhard's executive officer and now they are in a gala, and she was dressed in her SS uniform and with a glass of wine in her hands she was looking at a painting.

Some months ago Adelheid and Reinhard were called by the Kriminalpolizei to investigate a man called Karl Kraft having supposed ties to some men trying to assassinate the Fuhrer. And once they laid eyes on Him Adelheid Couldn't help but think that Karl looked as if she had met him somewhere, after that Kraft had offered them his services.

"Adelheid we have been called there's a fight between to what reports came two superpowered serial killers." Said Reinhard as he was accompanied by the SS officers Eleonore von Wittenburg and Beatrice Kirchisen, the latter was looking at the older blonde with admiration on her eyes obviously hearing stories of the Golden Valkyrie leading the last charge of the imperial army.

"Very well Reinhard, also is Karl joining?" Asked Adelheid wondering about their Magician.

"Yes he will join us to." Responded Reinhard.

"Alright then." The as they were about to leave Beatrice went in front of Adelheid.

"Hello I am Beatrice Kichisen, and I am a HUGE fan of yours." Said the Younger Blond as she shook Adelheid's hand.

"The pleasure is all mine, though I think we have to Hurry." Responded Adelheid. 

"Aye Ma'am." Saluted Beatrice.

Years later Wewelsburg castle.

Now Adelheid walked through the golden hall of Wewelsburg castle, she's called the Golden Einherjar, and now goes by the demon name Apollyon as she was named by Mercurius, and is Reinhard's General closely followed by the Einherjar aka the Commanders, not much had changed about her other then instead of the Swastika armband it was replaced by that of Reinhard's and she had a grey Shaul with Golden Runes.

Suddenly Adelheid felt a pull a call, she felt tired as if exhausted.

*What's going... on?* Thought Adelheid then her world faded into dark

Fuyki City.

Adelheid Stood on top of containers while laying her eyes on the Heroes before her, or at the very least Fragments of them, The golden Servant used his (oddly enough he looked irk, from what I've learned, Noble Phantasm, and launches them at me then I use my Assiah and two MP4 Sub Machineguns appear and shoot at the blades destroying them. 

"Rejoice Heroes of Yore once the Fog of war has been cleared all of you will join the Legions of Lord Heydrich, in the endless battlefield!" Declared Adelheid as she jumped from the container when a Golden Bf-109 g10 flew by and snatched the Golden Valkyrie.

At his Crow's Nest Kiritsugu Emiya had one thought in his mind "We need to stop her as soon as posible".
