Hello everybody let me state outright that this isn't a second chapter. I did say this is both a one-shot and a prompt for a reason.

The following is a set of notes regarding the story I just wrote for the sake of trying to help prospective writers who seek to continue this see my thought process. Main points will be marked with numbers for your viewing pleasure.

Of course, I don't mind if you take my concept for a plot and pretty much change everything to fit your needs. There are a ton of plot holes, and I'm looking forward to what everybody can come up with to improve the story. I am not against the changing of any scene, dialogue, or important story elements.

What I am against is changing the idea of sentient Personas to regular Persona. What interests me the most about Persona crossover fics is the idea of Personas changing the political landscape with their very presence through simply their identities.

1 – Persona Sentience) I use Vivian as a way to tie in Minato with Shirou. Vivian grants Avalon to King Arthur, and Avalon placed inside Shirou by Kiritsugu. Of course, you don't need to use this point. You don't even need to connect Minato with Shirou all that intimately. I included that section in order to display my how I want things to connect based on Persona identity and Servants of the Nasuverse.

***2 – "Do we go to war?") I wanted the story to sound dramatic, but I really don't like the line I wrote when the Shadow Operatives consider their options against magi. I wrote, "Do we go to war?" I didn't change or remove the line to help spark some ideas of some post grail war stuff, like Shadow Operatives vs Magus Associations (Although I really don't like the SO's chances in that). To me, "Do we go to war?" doesn't really fit the characters I am trying to portray. Do with that as you will.

3 - Personality) In terms of Minato's personality, I find The Crimson Lord's personification to be my personal favorite. I don't mind it being changed however. What I wouldn't prefer is a happy-go-lucky kind of MC. To me it doesn't really fit but hey, it's your story if you continue of this prompt. You do you buddy.

4 – Yu Narukami) For Yu Narukami not summoning his Persona, I attribute that to not being able to summon outside the fog or the Midnight Channel. The way I interpret it, is that in the outside world, you require an evoker (Plume of Dusk) in order to summon one. Of course you can summon one on your own, but it would be very mentally draining and result in a splitting migrane. See Strega.

5 – Relative Power) In terms of power levels, I don't think anything is so cut and dry. I'm not sure about Yu, but I think the rest of the persona users should be able to stand up to a servant only as a team. As you could see, the Personas that Aigis and Labyrs summoned barely performed against Assassin, and that was with prior perpetration in buffs. For Minato, the sentience of his Personas gives him an edge. A regular Persona is limited by spells and abilities Personas can normally learn. A Persona with sentience can use the abilities it knew in life (Noble Phantasms perhaps?). I am also a firm believer that Minato is more powerful then Yu. After all, what is the World to the Universe?

6 - Nyx) In this story I have Minato's Servant container acting as the Great Seal. I specifically wrote in that he cannot tap into that power, because that would just be way too overpowered. Do what you will with that, even change it if you'd like. Maybe he can have the Dark Hour as a reality marble if he can access that power? I don't know.

7 – Persona 1, 2, and Tokyo Mirage Sessions) I purposely left anything from these three games vague. I don't know much about Persona 1 and 2, but characters that may be core to the Shadow Operatives were listening in via communication devices like I stated in the story. For Tokyo Mirage Sessions, I only mentioned Itsuki Aoi in passing detail in order to give an example in the Alaya section of the story. I also mentioned Fortuna entertainment as financial means to the Shadow Operatives. It is up to you writers whether or not you want to involve characters from these games any further.

8 – Dialogue) I am a very bad writer, and I don't think I personified the characters in this story correctly. I also don't like how I wrote everybody's lines and their communication between each other. Change what you will.

9 – Assassin) As you've seen, I used the Assassin from Fate/Zero. This is due to my unfamiliarity with any other Assassin, and I know the one from Fate and UBW is not a true Assassin. The True Assassin from Heaven's Feel I don't know anything about because the movies aren't out yet.

10 – Atrum Galliasta) I realize a successful raid on a magi workshop is unlikely, so I'll leave that up to you. In my head, Atrum found the Shadow Operatives base through some sort of tracking spell. I don't think I personified the guy very well either. I have no good excuse to why Atrum couldn't summon a servant other than Assassin. I just didn't want to remove any other of the known servants in the 5th Holy Grail War. The only explanation I can think of is that he required Assassin's skill set in order to infiltrate the Shadow Operatives base. Also, I portrayed Atrum as overconfident in his victory and that is why he got all egotistical and had Assassin of all classes fight like a normal servant.

End: There are more plot holes/points that I wanted to get to but don't remember or I don't notice. Again this is just a prompt. You do what you want to do for this story, Thanks for reading, and I look forward to what you can come up with.
