Fate/Grand Order - Ritsuko Fujimaru & the Timeless Temple by IDKSomethingClever99
Fandoms: Fate/Grand Order

Summary
"So, my first day has ended and so far my boss hates me, I slept through orientation, received little to no training, have almost died multiple times, traveled through time to the year 2004 to fix a false history, became a Master, my boss died and now I have to go through all that crap again, like, 6 more times? What's next? Is the prom tomorrow?!"
Ritsuko has had a very long, very tiring day. Hopefully, she can power through with her army of Servants and save all of time and history.
Oh, by the way, I own absolutely nothing in this. Fate/Grand Order, along with its characters, belong to its respective owners, who are not me.

The Affections of the First Servant by Areeta9

Tags
Summary
The Chaldea summoning system, when used without a catalyst, often summons heroic spirits based on their affinity to the summoner. So what does it say, when you are the first spirit to come to their aid? Does it mean the same when you are but a common 3 star? What do you mean to her as she summons servants that are stronger, more useful than you?....What does she mean to you that you are asking these questions?

Summary
Between singularities, there was plenty of downtime for the last bastion of humanity.

Summary
It is the year 2005. Since Arthurian times, the holy grail has sporadically manifested in Britain, the center of mage craft in the world. Each time, it has chosen 7 people to seek it out, with the promise that the one to seize it for themselves shall receive whatever they most desire in their hearts. There was no predicting when the grail would manifest, only that when it did so, blood would be shed. Just over two hundred years ago, the holy grail war ritual was created, along with a council of mages, to try and reduce the collateral damage from the battle for the grail. And now the grail has manifested once more. But a dark force manipulating events from behind the scenes will ensure that this grail war will be like no other.....

Summary
Another bad crazy idea that sprung from my head while writing Carnival Phantasm. For some reason Shirou, Rin and Sakura are the three last Masters of Chaldea, the official timeline be damned. Rin and Sakura were raised together. And they all can summon crossover characters. Nothing is supposed to make any real sense. CRACK!

Summary
For the former Emperor, the idea of a wedding was a formality, not something to be emotionally invested in. It made him think of her, and he still had not found a way to process his lost love: His Goddess of the Moon.
