History FanFic / CrosswindsOfFate

* InTheBlood: The Ollivander family and by extention in her Formalcraft paper, Luna's theory is that one's magical affinity can be traced to one's genetic information. This is why Ollivander's tape-measure measure's seemingly irrelevant thing's such as the length of one's nose.

* UndyingLoyalty: Sakura will follow Shirou wherever he goes and will support him in all that he does. This is to the point that she actually switches from kyuudo[note]Japanese archery[/note] to European archery just because Shirou did.
** Rider is of course so loyal to Sakura that she has already deployed Bloodfort Andromeda to digest the entirety of the castle, [[WouldHurtAChild students included]], if Sakura were ever threatened.

* AnotherDimension: The ''Fate'' cast used the Second Magic to travel to the {{Potterverse}}. Unusually, they reveal this fact straight away, as the [[{{Masquerade}} alternative]] would be tedious.

* OddBedfellows: Downplayed, While Dumbledore and Rin are not enemies, their ideological differences regarding the bloodline matter do somewhat put them at odds with each other; they still work together, without prior planning, to discredit Umbridge.

* DimensionalTravelers: The ''Fate'' cast, by means of the Second Magic.

* {{Masquerade}}: Defied. Rin opens the interview with Dumbledore by telling him that her group is from another universe. When asked why they're so forthcoming, she explains that the alternative of [[FandomSpecificPlot pretending to be natives would inevitably be seen through, and make the truth seem less believable.]]

* AnotherDimension: The ''Fate'' cast claim to be from one very early on.
* BackgroundMagicField: The magi characters observe that the one in the Potterverse is stronger than the one in their home universe. For them, it means increased effects for their magecraft at the same cost, but they have yet to figure out what this means for the locals' magic.

* CultureClash: Examined in depth and played with. After unifying the two magical systems (with which there's quite a bit of overlap, regardless), the differences in culture could be considered the other major theme of the story.

** 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) interact in interesting ways with the blood purity issue in Harry Potter.

* {{Doorstopper}}: Shaping up to be one, as it's already at 130,000 words already despite being only eight chapters in length as of this writing.

* 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.

* AccidentalInnuendo: "I'm going to stab you (with Rule Breaker), and then you'll feel better (because it'll break the curse on you)."

* PokeInTheThirdEye: Harry pulls this on Snape when the latter gives him some poorly-timed Occlumency training. When Snape tries to get into his mind, Harry redirects the attack to a memory of the potions master blundly grabbing at the air in an attempt to catch him out after curfew.

* TornadoMove: Lorelei uses four tornadoes when fighting against Rider. Since they're fighting in Unlimited Blade Works, they become (in Shirou's own words) ''swornadoes''.

* OffTheRails: Various early changes to the story have ensured that the battle over the prophecy at the Ministry will never happen. Sirius has freed Kreacher, Harry has already made significant progress in Occlumency, and most damning of all, [[spoiler:Harry has already retrieved the prophecy from the Department of Mysteries]].

* {{Irony}}: Umbridge is a victim of the seldom-used Socratic irony at the hands of Dumbledore and the staff.
** When Saber visits [=McGonagall's=] office she spots a tapestry depicting Cú Chulainn, William Wallace, and a third man she does not recognize. When asked, the professor tells her that the man is King Arthur.

* NotHelpingYourCase: After deciding not to issue a Sealing Designation on Shirou, Lorelei is accidentaly cursed after grasping a cursed sword in the middle of a fight and Shirou attempts to use Rule Breaker to get rid of the curse. After hearing the explanation of what Rule Breaker does, Lorelei asks him not to give her more reasons to regret not assigning a Sealing Designation on him.

* NoodleIncident: At some point between the ''Unlimited Blade Works'' good end and the present, something analogous to the events of ''Heaven's Feel'' happened, leaving Sakura with access to her dark form, Rin in possession of her version of the Jeweled Sword of Zelretch,which he names the Jeweled Sword of Tohsaka, and Rider resummoned despite having been killed off in the Grail War.

* NoodleIncident: At some point between the ''Unlimited Blade Works'' good end and the present, something analogous to the events of ''Heaven's Feel'' happened, leaving Sakura with access to her dark form, Rin in possession of the jeweled sword of Zelretch, and Rider resummoned despite having been killed off in the Grail War.

* IgnorantOfTheirOwnIgnorance: Umbridge shows how ignorant she is of the world by stating that "Muggle" biology has no bearing on the Magical World, or how just repeating a belief verbatim does not make it true without any empirical evidence.

* TwentyMinutesIntoTheFuture: What the ''Fate'' cast's home universe is relative to the world they're visiting. The fic follows the books' timeline, resulting in about a twenty year time gap.

* 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.

* NotHelpingYourCase: After deciding not to issue a Sealing Designation on Shirou, Lorelei is accidentaly cursed after grasping a cursed sword in the middle of a fight and Shirou attempts to use Rule Breaker to get rid of the curse. After hearing the explanation of what Rule Breaker does, Lorelei asks him not to give her more reasons to regret assigning a Sealing Designation on him.

* BookDumb: Ron, but not to the normal stupid levels shown in most fanfiction, he's just unmotivated.
