History FanFic / CrosswindsOfFate

* MarryThemAll: While not explicitly married, Shirou, Saber, Rin, Sakura, and Rider's relationship fits this trope.
* MuggleBornOfMages: The wizards are led to believe that Saber is a squib.

* AllMythsAreTrue: Rider reveals that Umgubular Slashkilters and Heliopaths are real, only the Ministry would never be able to control the latter as they are Phantasmal Beasts.

* {{Badass}}: A given for the ''Fate'' cast, who in the case of the magi characters have grown even more powerful than they were at the end of the visual novel. In particular, Rin has her jeweled sword from the ''Heaven's Feel'' route and Shirou has mastered his Reality Marble.
** UnderestimatingBadassery: The ''Fate'' cast invoke this by going to great lengths to conceal their talents. Rin and Sakura teach branches of magecraft outside their specialties, while Shirou and Saber hold back in combat. Rider is kept completely hidden. It's also inverted, as the ''Fate'' cast assume the wizards are doing the same, and consequently ''overestimate'' them.
*** Yet somehow, Umbridge manages to further underestimate them by mistaking Shirou's CurbStompBattle with Dawlish for the auror holding back too much.

** Dawlish, as per his status in canon. It's even worse on him than usual, because of how heavily Shirou overestimates him.

* WrongContextMagic: The central premise of the fic is the magi characters trying to unify two very different systems of magic. Exacerbated by the fact that while the ''Harry Potter'' characters can learn the Type-Moon cast's magecraft, the opposite does not hold.

** Rin is not pleased when she discovers that Moody's magical eye allows him to see through clothing.

** When the topic of magical pedigree gets brought up in class at one point, the magi idea that some bloodlines can be inherently stronger than others (through magical crests and eugenics) has some interesting interactions with the blood purity issue in Harry Potter.

*** The blood purists are naturally quite pleased to learn that the magi characters seemingly agree with their point of view.

* DeathByAdaptation: Because Harry never went back to the Dursleys over the summer, when the Dementor attack happens all three Dursleys get kissed.
