''Big Sister'' by Academia Nut (author of ''FanFic/ThousandShinji'') is a story with a similar premise to ''FanFic/{{Lovehammer}}'': A MagicalGirl ends up in the ''TabletopGame/{{Warhammer 40000}}'' universe before the Heresy and leaves a big mark. But the similarities end there.

When the future Primarch Vulkan arrives on Nocturne, he does not arrive alone, a teenaged girl, still recovering from crippling injuries even before somehow finding herself stranded on a DeathWorld, comes across the infant Primarch and brings him to the nearest settlement through sheer force of will.

The two grow up together as the girl recovers, eventually helping her little brother battle Dark Eldar Raiders. The girl takes the nickname of Ga’ri, meaning "Ash Maiden", a name she finds fitting, despite the sometime negative connotations that come with it. As she regains the use of her magic, Ga’ri also helps her "Little Brother" grow in mind and spirit as fast as he does in body. When The Emperor lands on Nocturne, he finds his lost son to be a very different man than even he was expecting.

* AccidentalMisnaming: One of the reasons Ga'ri takes up the name is that it turns out that the problems certain people had in saying her name in her own series are even ''worse'' when the local tongue doesn't even have some sounds common in Japanese.
* AmazonBrigade: The Gae'ri, a team of female psykers modeling themselves after Vulkan's sister.
* AnyoneCanDie: [[spoiler:even ''Ga’ri'' ([[HesJustHiding maybe]])!]]
* ArtifactTitle: [[spoiler:Ga'ri disappears early after the fight with Puelammi.]]
* BigSisterMentor: Ga'ri. It's right there in the title.
* ChasteHero: Vulkan explains to [[spoiler:Fara]] how he doesn't get love. [[spoiler:subverted later when Fara offers to teach him... and apparently succeeds, as his daughter is living proof of.]]
* CoolBigSis: Half the point of the story is Ga'ri being this. To a ''Space Marine Primarch'', mind you.
* CurbStompBattle:
** [[spoiler: An Avatar of Khaine appears to fight Vulkan]] and does not last very long.
** In a more humorous example, Ga'Ri in Vulkan and the Emperor's game. To quote the Emperor, [[spoiler: [[PrecisionFStrike "BULL! SHIT!"]] as ''half of his army is wiped out in less than thirty seconds.'']]
* DeadFic: The story has not been updated since late 2010.
* {{Deconstruction}}: Vulkan basically tells the Emperor that choosing to follow someone because they beat you in one contest is not very smart; that one test is hardly the be-all and end-all of the qualities that make a ruler great.
* {{Determinator}}: Ga'ri for using all of her power to shelter the infant Vulkan [[spoiler: despite still recovering from that whole mess with the Gadget Drone]]. Also for singlehandedly recovering from the wounds and infection sustained for doing so, and finally standing up on her own two feet after the first Dark Eldar attack and literally defining the concept for Vulkan.
* FailedFutureForecast: Konrad Curze is left perplexed when it turns out Vulkan is able to completely defy his visions of death and despair. While he's briefly left paralyzed by [[HopeIsScary the hope]] it is possible [[ScrewDestiny to destroy the future his visions predict]], Vulkan convinces him to take arms and fight the future.
* GetAholdOfYourselfMan: Vulkan uses his head and delivers one to the Night Haunter.
* HeroicBSOD [[spoiler: Vulkan after losing Ga'ri]]
* MoodWhiplash: When the Mysterious Stranger [[spoiler: The Emperor in Disguise]] asks for Vulkan's loyalty, Vulkan claims that there will be a series of Trials. Now, for the Emperor, this sort of thing is fairly common when meeting new sons- after all, Leman Russ challenged him to drinking and fighting. The atmosphere is fairly serious... and then Vulkan calls out for board games to be brought to him. The Stranger is visibly confused.
* OhCrap:
** [[spoiler:The Emperor secretly gathering samples of Ga’ri's DNA.]]
** Puelammi [[spoiler: getting possessed]].
** See also TheReveal below.
* PapaWolf: When [[spoiler: Eldar attack Nocturne]], Vulkan is not happy.
* TheReveal:
** It's hinted but never outright stated until the third chapter, when [[spoiler:she pulls out Raising Heart]], that Ga’ri is [[spoiler:[[Franchise/LyricalNanoha Nanoha Takamachi]]]].
** [[spoiler: Vulkan has a ''daughter''.]]
* SecretTestOfCharacter: Vulkan's first training with the Salamanders.
* ShoutOut:
** Vulkan asks Jaghatai Khan "What is best in life?". [[UsefulNotes/GenghisKhan Three]] ''[[Franchise/ConanTheBarbarian guesses]]'' what Khan says his original answer would have been.
** After killing a Dark Eldar raider: "If it bleeds, we can kill it."
** [[Film/TheShining "Heeeeere’s Konrad!"]]
** "Even if the Mon-keigh were here and had launched at the same time as us, to get through the interference in the Warp would take some sort of [[Memes/TabletopGames navigational genius]]..."
** Vulkan built a proto-force weapon [[Film/IronMan on Nocturne with a hand-pumped charcoal forge.]]
* SillyReasonForWar: A planet rebels against the Imperium because ''The Emperor's eyes are the "wrong" color''. As one Scout puts it:
--> “Please tell me that our mission will be to assassinate those idiots and I get to use the sniper rifle this time.”.
* ThatCameOutWrong: "I want your sister." -{{beat}}- " “Correction, the Order ''needs'' your sister on its side."
* TooFastToStop: When Ga'ri puts up a barrier in the way of a Dark Eldar speeding at her, the results are... [[LudicrousGibs crunchy]].
* TheWoobie: You'll want to hug Konrad Curze.
* WhamLine: We get this said by Vulkan when asked by Teruel if the Emprah doesnt take well to Vulkan [[spoiler: having a daughter]]
-->[[spoiler:“And if he too is a threat?” Teruel asked “Then the galaxy can burn,” Vulkan stated.]]
