History Fanfic / FateSoulsAndSingularities

* AdaptionalOriginConnection: In canon it was never elaborated who the mother of Gwyn's children was. Here, it's eventually revealed to be [[spoiler: Velka]]

* Adaptational Expansion: The story expands on many plotpoints. In particular, the Dark Souls universe is given more depth which includes it's characters, locations, and history.

* MamasBoy: Several characters teasingly interpret Ash's relationship with the Fire Keeper as this. While somewhat flattered, the Firekeeper herself is against this, as she sees her actions as molding him into a LaserGuidedTykebomb which she ''knows'' is the opposite of being a GoodParent.

Fate: Souls and Singularities is a crossover fanfiction between ''VideoGame/FateGrandOrder'' and ''VideoGame/DarkSouls'' (As well as every other Creator/FromSoftware franchise minus ''VideoGame/EldenRing'') written by [[https://www.fanfiction.net/u/14443864/Mundatorem Mundatorem]]. It can be read on Fanfiction.net [[https://www.fanfiction.net/s/13871792/1/Fate-Souls-and-Singularities here]] or on [[Website/SpaceBattlesDotCom SpaceBattles.com]] [[https://forums.spacebattles.com/threads/fate-souls-and-singularities-dark-souls-fate-grand-order-crossover.979413/ here]].

** As the story goes on, it deconstructs the idea of summoning servants from alternate timelines, which happened in ''Grand Order'' as Chaldea started summoning servants from the Lostbelts. While the servants from the Lostbelts had some issues with Proper Human History, they were ultimately willing to work with Chaldea for the sake of saving mankind. By contrast, several servants from ''Dark Souls'', especially [[spoiler:Gwyn]], fundamentally ''cannot'' get along with Chaldea, which has disastrous results in the London Singularity - [[spoiler:Chaldea ends up having to face a Beast ''with no way to oppose it'' when Solomon causes Ash to become the Beast of Mercy, while Gwyn, the TopGod of ''Dark Souls'', outirght tries to massacre Chaldea due to FantasticRacism against humans]].
** Chaldea's nature of recruiting every servant it can, even those with motivations that conflict with one another, also gets taken apart. While most servants in canon are willing to grit their teeth and work with their enemies, with some even making peace, this doesn't happen when Ritsuka welcomes [[spoiler:Ash]] back into the fold after [[spoiler:the latter turnd into the Beast of Mercy]], in part because [[spoiler:he turned on his allies, and to many servants, TreacheryIsASpecialKindOfEvil. Ritsuka is the only reason they didn't execute Ash for his betrayal]].

* JerkassHasAPoint: [[spoiler:As soon as Fujimaru wakes up, Arkon immediately goes to him and asks that he not hold Gwynevere's actions against her should she be summoned [[AbusiveParents despite her crimes against Ash.]] While his utterly dismissive attitude of Ash's circumstances due to his [[MyMasterRightOrWrong biased faith in the gods]] and his [[FantasicRacism his status as an Unkindled]] is rather cruel, he does raise a good point that it'd be utterly unfair and hypocritical for them to hold Gwynevere's crimes against her while being willing to forgive Ash for nearly killing them all and welcoming other Servants at Chaldea have also commited rather heinous crimes in their lives as well such as Sulyvahn and Leonidas.]]

* RightForTheWrongReasons: [[spoiler:The revelation that the world of ''Dark Souls'' is/was a Lostbelt unintentionally validates Gwyn's belief that keeping the First Flame going was needed to protect the world, as once it was snuffed out, the Counter Force pruned that timeline. However, this is also implied to be a SelfFulfillingProphecy, as his choice to create the Darksign corrupted the Dark Soul, which might have either wise been able to sustain the world]].

* SelfFulfillingProphecy: [[spoiler:Gywn's beliefs regarding the First Flame turn out to be this - the world of ''Dark Souls'' was actually a Lostbelt in the ''Fate'' timeline, with the First Flame being it's Fantasy Tree equivalent. The Dark Soul ''also'' had the potential to sustain the world/timeline ''until'' Gwyn created the Darksign. So allowing the Forst Flame to die did end the world, but only because Gwyn corrupted the one other thing that could sustain it]].

** [[spoiler: Gwyn]] looks at the previous example and laughs. He completely steamrolls ten servants without even slowing down, and it takes the combined assault of Ash, Mordred, Stahl, Percival, Nobunaga, and Scathach to give him even a moderate amount of trouble, and in the end, it requires the use of an EX-rank, Anti-World & Anti-Divine Noble Phantasm to stop him, and even then he's still not dead.

* WorfEffect: Quite a few servants are on the receving end of this courtesy of [[spoiler: Gwyn]], with Jeanne, Berserker Lancelot, Cu Chulainn, and Scathach being among the most notable, with each of them either being subject to a OneHitKill, or easily swatted aside without doing anything. The most striking example is Mash's Lord Chaldeas, which after having been shown to be capable of withstanding the full force of [[StarterVillain a grail empowered Saber Alter's]] [[WaveMotionSword Excalibur Morgan]], is shattered like a pane of glass from a single one of [[spoiler: Gwyn's] lightning bolts.

* WakeUpCallBoss: [[spoiler: Gwyn]] serves as this in the London Singularity. Whereas most of the previous enemies could be handled in a straight fight by Servants, with even the Demon Pillars capable of being defeated by a group of normal Servants without too much issue, [[spoiler: Gwyn]] is shown to be night-unbeatable by normal Servants, effortlessly plowing through Servants and Noble Phantasms capable of repelling even the strongest prior opponents. It's best exemplified when Mash brings out Lord Chaldeas, which had been able to protect them against the likes of [[StarterVillain Saber Alter's]] strongest attack, [[WaveMotionSword Excalibur Morgan]], it's completely shattered by a single attack from [[spoiler: Gwyn]], which required pretty much no effort on his part.

* DownerEnding: To the Singularity 3.5 Arc.
** Tarkus and Gordin get killed in horrific manners trying to defeat the Dragon Army and restore PHH.
** Marie kills [[spoiler: Lartoria Alter]] in revenge for murdering her friend Tarkus, who died protecting her, but it’s implied that doing so hasn’t truly resolved anything for her and has only led to the beginning of her becoming an EmptyShell from the trauma of people dying to protect her over and over.
** Akal dies in front of her children, who charge at the Servants defending PHH in order to avenge their mother. Despite their best efforts and the Chaldean Servants’ own disgust at having to murder frankly innocent children, the children are all massacred despite their upgrades over the previous generation of New Camelot’s dragons, dooming the dragon race’s hope of coexistence with humanity in a new History or being the new humanity themselves.
** To top it all off, despite Kalameet’s proclamation to fight to the very last breath for his people and their dream of having a home for themselves where they didn’t need to fear being killed or exiled for simply being different than humans, he gets Command Sealed to kill himself right in front of Olga as he’s preparing for his final charge. Worst of all, he was Sealed to kill himself not by the way he wanted to go out, dying by the hand of someone who had a dream like him and who had the will and hope to fight to the end, but by someone who was purely just disgusted at his dream itself. He dies broken and in despair, wondering if he ever had a chance to win.
** In addition, the person who actually had the Holy Grail and Seals, who murdered Kalameet out of disgust for a dragon desiring agency and equality, [[CreepyChild Arleno]], is implied to be serving [[spoiler: Ash Alter, the Lord of Hollows]] in a quest to strengthen Olga to be a better Master. In fact, it turns out the entire Singularity was created just to act as a test for Olga to see if she had the will to fight for humanity no matter what, which she passed. While Arleno and his Lord are implied to be genuinely fighting for the restoration of PHH as well, Olga is understandably horrified that someone as genuinely heroic as Kalameet was used and tossed aside like nothing out of hatred.
** Finally, after it being revealed to Kalameet that he was a puppet all along, and Olga being horrified by what the Singularity had been used for, Kerry and Romani start screaming about how the Saint Graph quantity is heavily increasing in London, implying that the Counter Force just started spamming Servants into the London Singularity, which is horrific news considering the CF is normally able to get by with one or two additional help for Chaldea even during the Incineration to restore PHH successfully. In addition, a Noble Phantasm is activated which [[spoiler: destroys the stability of the London Singularity, and starts more space-time quakes like the ones during the Incineration]].
** Worst of all, a parting remark from Arleno implies that a [[BeastOfTheApocalypse Beast of Humanity]] has just been woken up by the calamities occurring.

* BigBadEnsemble: As of Singularity 4: XXVII, [[spoiler:

* TheChainOfHarm: Much of Gwynevere's poor treatment of her son, [[spoiler: Ash]], can be traced to how her own father, Gwyn, raised her. That being said, Gwyn's treatment of her children is all over the place, whereas Gwyn treated all of his brood like crap.

While the servants from the Lostbelts had some issues with Proper Human History, they were ultimately willing to work with Chaldea for the sake of saving mankind.

** [[spoiler: Gwyn had no qualms subjecting his own daughter Gwynevere to ElectricTorture for daring to support a human.]]

** In the London Singularity, [[spoiler: Gwyn, Lord of Sunlight]] against Chaldea for a long while, being so quick because of his [[spoiler: Authority of Light]] and stats that he was nearly killing one Servant ''per second.'' Averted in that it eventually becomes a more even fight.
