The HOLY GRAIL WAR Meme
Who will it be?
For those unfamiliar with Fate/Stay Night or Fate/Zero, you can find a better explanation of the Holy Grail War here. (Note: The Holy Grail War in Fate/EXTRA functions in a dramatically different way, and one not followed for purposes of this meme.)
Instructions
1. Comment with your character. In the subject line, put that character's name, canon, and which role (Master, Servant, or either) you would like them to fulfill. Though not mandatory, it would be preferred that you give a brief summary of your character as they will (most likely) be AU'd into the setting. (NOTE: If your character can fill the role of Servant, I suggest you state which class(es) -- Saber, Lancer, Archer, Rider, Caster, Assassin, or Berserker -- they fall into.)
2. Reply to others' comments. Pick your character's role (and the other character's if they list "Either" as their preference), then use the RNG to pick a scenario that fits the two characters' roles.
3. Enjoy! Though there might be triggers, depending on how the prompts are interpreted.
TWO MASTERS
1. Battle. Who says that Servants get to have all the fun? After all, most Masters try to kill each other, too. Whatever the circumstances, the two of you are locked in a fight. Neither of you are willing to use your Command Spells just yet, so no Servants here. Just two magi duking it out.
2. Alliance. There's a bigger threat out there. Either one Servant is exceptionally powerful, or the situation has changed and the participants need to take action aginst it. One way or another, you're teamed up with one of your rivals for the Holy Grail. How long will this last before you try to stab each other in the back? Or, will something more develop?
3. Protection. Uh-oh! One of you has lost your Servant! Unfortunately, there's no way you'd get to the church safely on your own, so the other one will help you get there! Or maybe you don't trust the priest presiding over the Holy Grail War and are giving shelter to them yourself? Given their track record, no one would blame you.
4. Death. One or both of you lay dying. It might have been by the other's hand, or by someone else's entirely. How will you spend your last moments in the presence of one of your rivals?
5. You, Too? Surprise! You may have been friends before, but you've just discovered that you're both Masters! How will you handle this revelation?
6. Wild Card. Roll again, pick one of the previous options, or make one up!
1. Are You My Master? The summoning is complete. Whether intentional or not, catalyst or not, a magus has summoned a Servant. What kind of meeting was it? Was everything totally under control, or did a hitch occur? Or maybe it happened in the middle of a life-or-death situation!
2. Identity. Either the Servant has flat out told the Master their identity, or they unleashed their Noble Phantasm. Either way, the cat is out of the bag. How will the Master react, now that they know their Servant's name and legend? Will anything change between the two?
3. Battle Aftermath. A battle has just ended. Who participated? Are either of you hurt? Did the Master have to use a Command Spell? Any number of things could have happened here.
4. Discord. Uh-oh. It looks like the Master and the Servant don't get along. Here come the arguments! Don't do something stupid, like waste a Command Spell over a triviality...
5. Love. And then, there's the opposite. Sometimes Masters and Servants fall in love with each other. How will this affect things?
6. Wild Card. Roll again, pick one of the previous options, or make one up!
1. Battle. This is what usually happens when two Servants meet -- they duke it out. This probably says enough as it is.
2. Alliance. There's a bigger threat out there. Either one Servant is exceptionally powerful, or the situation has changed and the participants need to take action against it. One way or another, you're teamed up with one of your rivals for the Holy Grail. How long will this last before you try to stab each other in the back? Or, will something more develop?
3. The Grail Dialogues. Maybe you're not interested in fighting just yet. Maybe you just want to sit down and talk with the other Servant. Find out what they want, what makes them tick. Get some wine while you're at it -- nothing like good wine to go with good talk!
4. Death. One or both of you lay dying...again. It might have been by the other's hand, or by someone else's entirely. How will you spend your last moments in this War in the presence of one of your rivals?
5. Identity. Congratulations, you've just learned each other's identities! Will this change the situation, or will you press onward?
6. Wild Card. Roll again, pick one of the previous options, or make one up!

[He stumbles back, almost falling on his ass- but when he heard the Servant speak:]
Archer! Yes, I was hoping for an Archer, this is perfect!
[Lookit this eager puppy. He starts looking on his body for his seals, all while still talking]
Oh, sorry- I'm Aiba Takumi... I guess I'm your Master, huh? Oh... is there something specific I'm supposed to say I can't remember-
[He might be hunting down his notes. Excuse him]
no subject
[He smiles at the note grabbing - this boy is reminding him of Ritsuka, oddly enough - and quietly steps out of the circle towards Takumi.]
No, no - this is fine, you needn't worry yourself with any ritual saying. Now - I suppose that you summoned me to fight in a Holy Grail War? As such, I would like to hear the wish you would make upon it.
[Most likely something idealistic or silly, honestly.]
no subject
Not exactly. Archer, as your Master I want you to help me destroy the Grail War itself.
[Well]
1/2
Moriarty goes stock still, his eyes going wide and his mouth dropping open.
He's genuinely speechless, at the desire his Master has for this war.]
no subject
Wahahahahahaha!! Oh, of all the things...!
[He understood, now - why he was summoned here, above all else.
After all, he was James Moriarty. The Man who dared to write down equations speculating on the force it would take to destroy the world itself, someone who hated Mages and their ways.
When he manages to finish laughing, he flicks a tear out of his eye before nodding.]
...Then I will follow you in your goal, Master! I swear to you that I will help you destroy the Grail itself, and dash all the hopes of the other Masters in this war! Yes - it's more than fitting for myself!
no subject
What- you don't even want to know why? I was expecting to have to discard my seals and run to the Church if you looked like you were unhappy with losing your chance at winning...
[At least he thought through the risk of making this request to a being called from the very thing he wanted to ruin- and the importance of his Servant being completely in his corner to even have a chance.]
no subject
[Which, surprisingly, was the truth - the grail was just another variable in the Equation, and he had little to regret about his life. Those few regrets that he did have, well...he wouldn't do something foolish like attempt to change them.
There was no changing the past, after all.]
I despise Mages, after all. Of course I would happily participate in destroying their hopes and dreams!
no subject
So it's probably not surprising when to Archer that his eyes lit up at the mention of the Servant's hate]
Good. I've seen the disasters they leave behind thanks to what my Mentor has shown me. I can't... I can't stand the idea of one of them getting a Wish or whatever secrets the Grail has...
[Rather than getting the Grail and wishing to undo or change these crimes he wanted to take the chance away from them. There was a core of spite in that logic.]
