Holy Grail War

=Introduction=

A Holy Grail War, also known as a Heaven's Feel, is a series of rituals performed by seven mages, known as Masters. Each of the Masters involved summon a Servant to aide them in battle. Each Grail War is hosted in a suitable area, usually a city of some kind, that allows varied strategies and tactics to be used. Grail Wars are resolved by each pair of Master and Servant fighting one another, until only one pair survives.

In Canon
Holy Grail Wars are hosted within very specific areas. The Type-Moon universe contains several types of True Magic which are often considered to be miracles; manifesting the Holy Grail is one of these miracles, and requires a large amount of magical power and structure. In the Fate series, the Holy Grail War takes place in one city, which is built on top of a series of leylines and caves that have been converted into a giant ritual platform for the summoning process.

The Holy Grail itself takes form only when 6 of the 7 summoned Servants are defeated, and uses the power of their souls to grant an all powerful wish to the winning pair. Unfortunately, years of mages tampering with the summoning ritual have led to some servants who are not pure heroes being summoned. These anti-heroes and villains have at some point tainted the Grail itself, causing the wishes granted to become twisted and malicious, not unlike a Monkey's Paw or Djinn's wish granting ability.

In Fate/Discord
The Discord Grail Wars have had varying roster sizes, not always being limited to 7 pairs, in order to accommodate the current total of players. The central concept of the Grail War, that each Master is pursuing a wish to be granted by the Grail, is carried over with few exceptions. Within the Discord Grail Wars the hosting area is less restrictive, but often hint at being chosen or constructed deliberately for the ritual. The following areas have hosted a Discord Grail War so far.
 * The First War, hosted in Fujitsu City.
 * The Second War, hosted in Zephyranthes.
 * The Third War, hosted in Western World (?).
