->It was just a small wish: To live with their master and their friends as those uneventful days passed by, to see him grow up as he chased his ideals by his own strength. To become an ally of justice; a hero who can save everyone.

A {{Crossover}} story between ''VisualNovel/FateStayNight'' and ''Franchise/LyricalNanoha'' in which the [[ArtifactOfDoom Book Of Darkness]] binds itself to Emiya Shirou instead of Yagami Hayate. A interesting idea with a good deal of potential, and a greater amount of work put into it. Even though it is still in its infancy, it delivers some well-done character interactions. The initial development of the Wolkenritter's feelings towards Shirou as their master are truly endearing and heartwarming.

Also, as the author himself put it: "Fraggle presents: Fate/Night Sky The only fic that has [[ItMakesSenseInContext induced Avalon rage in it's readers]]."

Can be found in its dedicated forum thread in [[http://forums.nrvnqsr.com/showthread.php/1000-FSN-x-MGLN-crossover-Fate-Night-Sky Beast's Lair]]. A mirror is available in [[http://www.fanfiction.net/s/7871193/1/Fate_Night_Sky fanfiction.net]]. Unfortunately, with the last update being nearly three years old--and no activity from the author for two years--this is certainly a DeadFic.


!!This page only deals with tropes appearing in the story itself. For those common to F/SN and Nanoha check their respective trope pages.

!!This fanfic contains examples of:

* BattleInTheCenterOfTheMind: Shirou's mind becomes the scenario where [[spoiler:the Book of Darkness and Avalon]] manifest themselves and confront each other. [[spoiler:The former trying to consume more of Shirou's prana to fill its pages and the latter keeping the former's influence partially at bay.]]
* BigEater: Vita.
* ChickMagnet: Signum.
** EvenTheGirlsWantHer: In a OneeSama kind of way.
* {{Cliffhanger}}: Fraggle has a liking for these at times.
* ColourCodedForYourConvenience: The Wolkenritter's new barrier jackets.
* DarkerAndEdgier: Compared to the original Nanoha A's.
* [[spoiler:EyeScream: The result of Shirou reinforcing his eyes incorrectly when trying to hit a target.]]
* FateWorseThanDeath: [[spoiler:The eventual fates of the Liese Twins.]]
* FashionableAsymmetry: The first thing Shirou notices when he sees [[spoiler:Reinforce]] for the first time:
--> "Why do your wear socks that don't match?"
* IllGirl: {{Invoked|Trope}}. To justify her [[TheAgeless lack of physical growth]], Vita has to pretend she is suffering from a deliberately poorly-defined "hormone imbalance" and play the part of a sick and fragile little girl in public. Predictably, this annoys her to no end.
* IWasJustJoking: Shirou jokingly suggested dressing the Wolkenritter as "a bunch of vengeful oni" to keep potential enemies from recognizing their civil identities. Cue Vita's PuppyDogEyes.
* KillItWithFire: Shamal and Taiga's combined efforts in making dinner after [[spoiler:Shirou was overloaded by the [=BoD=]]]
-->The healer stammered as she tried to save her dish.
-->"How can you kill something with fire if it's already burning?" Vita murmured.
* MomentKiller: '''''Dammit, Avalon!'''''
* MythologyGag: Shirou missing the target on purpose in front of Ayako.
** Shirou jumping the bar while Rin and Sakura watch. [[spoiler:With a twist. After Rin leaves, he eventually clears the bar after briefly tapping the power of the spell [[{{Flight}} Slei]][[PowerGivesYouWings pnir]].]]
** Apparently Gilgamesh obtained [[CoolStarship the Vimana]] from Al Hazard, and he was responsible for the destruction of their homeworld. There's a ''reason'' Ea is called an Anti-''World'' Noble Phantasm.
* OnlyOneName: Averted with the Wolkenritter as they needed proper surnames for their [[{{Yakuza}} Yakuza]]-provided fake [=IDs=]. They now go by Signum and Vita Ritter (posing as sisters), Shamal Grün and Zafira Wolf.
* PoisonousFriend: Signum specifically refers to Shinji as such.
* PuppyDogEyes: Vita uses these on Shirou to great effect.
-->Vita scooted closer to him, staring at him with eyes that had somehow grown double their size as they sparkled at him. It was almost like a child looking at her parent after being promised the greatest birthday present ever, only for them to keep it out of reach.
* ShipTease: One could make a case for [[spoiler:Zafira×Taiga]].
* TeachMeHowToFight: Similarly to [[VisualNovel/FateStayNight canon]], Shirou doesn't accept the fact that he is nominally entitled (and tactically encouraged) to remain behind the front lines and tries to convince his guardians to train him. [[spoiler:After a while Zafira and then Signum end going along with his wishes.]]
* WhamEpisode: In chapter 8 not only does Shirou meet [[TheWormThatWalks Zouken]] but Gilgamesh is seen observing him as well.
