I'm not sure where the 700+ statistic came from, unless you're referring to the Church investigations which were over a supposed grail, in which case that's inherently different from the Holy Grail War and should not be compared to one another. The reason it's considered a pittance is because it is backwater for an association magus (Japan/Asia in general and all that) and because of the three families involved in its creation, only one is noteworthy to a western magus, and even then they're recluses who barely communicate with anyone. As far at the Fate/Stay Night line is concerned, there have only been 5 Holy Grail Wars in the sense of the grand ritual. The Fate/Zero war is the 4th HGW. The only glimpse we have of any war prior to that is in Fate H/A where the characters are forced into the role of the participants of the 3rd HGW. Fate/Extra takes place in the Moon Cell, which sort of allows for additional bullshittery because it's essentially a stronger, alien grail. Also on the Moon.False! Waver competed in Another Grail War with Iskandar! There is the Moon Cell, and then there's the Grail War of Fate/strange fake. There actually are quite a few Grail wars.
I do not have skype, so let's discuss using PMs.Fate/Extra isn't the Fuyuki Grail War. The Fuyuki Grail is like the 726th Grail War or some such number. In fact, Waver Velvet (Lord El-Melloi II) actually fought in a second Grail War with Alexander the Great (watch Fate/Zero.) In fact, the Mage's Association considers Grail Wars to be backwater rituals because there are so many.Ah, my Fate knowledge is clearly rusty. By "The Fuyuki Grail War", you mean the war that takes place in Fuyuki City, right? I thought there has only been five Grail Wars as of Fate/Stay Night, and four as of Fate/Zero? Anyway, it's obvious that I have some misconceptions about the lore, so if you have Skype, we could talk about it over the messenger. Otherwise, we could converse through PMs, as this conversation seems like it's gonna take a little while to clear up the confusion.
