Fate/Magi: The War of Magic (Magi AU)

"Imagine that the world is made out of love. Now imagine that it isn't. Imagine a story where everything goes wrong, where everyone has their back against the wall, where everyone is in pain and acting selfishly because if they don't, they'll die. Imagine a story, not of good against evil, but of need against need against need, where everyone is at cross-purposes and everyone is to blame."

This is an alternate universe using the world of Fate/Zero and/or Fate/Stay Night and the characters of Magi. I suggest having watched/read all three before reading this, although I've tried to make it only necessary to have read/watched Magi.
*I do not own the Fate series, nor Magi, nor any of the characters, etc*
**Obviously there's gonna be a lot of major character deaths so you have been warned**

The Holy Grail War has been around for over the past two hundred years; seven mages chosen by the Grail gathering every fifty or so years to fight to the death for the infamous Grail- an item that can grant any wish to whomever claims it.

The seven mages that are chosen to fight are granted three Command Seals each by the Grail. These Command Seals are used to control the will of a Heroic Spirit -a familiar-like servant- to fight for them and help them win the Holy Grail. Servants are heroes of the past, present, or future, and are split into seven different classes. Three being the knight classes: Saber, Lancer, and Archer; and four the cavalry classes: Caster, Rider, Assassin, and Berserker.

Now, for the seventh Holy Grail War, seven mages are gathered, all with different reasons for fighting. What perils will these seven face in order to get what they desire? In a battle for their lives, who will win, and who will perish at the hand of someone the may have once called a friend? (58K words and counting)
