S.E.R.V.A.N.T.s

An unused S.E.R.V.A.N.T. frame that has yet to be activated.

Technology now has a symbiotic relationship with Magecraft, which is further proven by the newly developed S.E.R.V.A.N.T. Mystic Codes.

S.E.R.V.A.N.T. Mystic Codes are similar to normal Mystic Codes. They are magical artifacts that are similar to golems and automatons in design, but with modern technology serving as their structure. Their chassis and exoskeleton is entirely manmade, being a husk that is similar to a cyborg-like body merged with their properties enchanted by magecraft.

S.E.R.V.A.N.T. Mystic Codes enable the summoning of Heroic Spirits in the absence of the Holy Grail.

Origin

The creation of S.E.R.V.A.N.T. frames is still a mystery. No one knows who created the first processor, but it most likely was someone from after the cataclysm. Aside from containing 10% of the Grail’s data, the processor is also engraved with information on what happened to humanity after that tragic event, keeping summoned Heroic Spirits up to date with the most recent happenings.

However, this is most odd, since the Holy Grail is theorized to have been destroyed after the cataclysm, so it is unknown on how the Grail’s data could be stored inside a processor.

Regardless, Republic is credited as the organization that first discovered it.

Republic & the Neo Holy Empire

Currently, all commercial S.E.R.V.A.N.T. factories are owned by a single organization known as Republic. These frames are sold in most major cities at a premium. Anyone can purchase them, provided they have the necessary funds.

The Neo Holy Empire produces their own S.E.R.V.A.N.T. frames as well, albeit at a much smaller scale and not for sale to the common populace. Only church-affiliated individuals may purchase them. Their technology also slightly differs from that of Republic’s.

For more information, please refer to Republic & NHE Frames.

Spirit Core

The Core of a S.E.R.V.A.N.T. frame is designed on principle to be the closest thing possible to a Spirit Origin Core. Engraved in that core is a powerful processor, one strong enough to hold a mere 10% of the lost Holy Grail’s data within.

These complex calculations and remnants of True Magic are normally idle, but activate upon interacting with a summoning ritual. A singular command is then run through the processor, the only feasible command out of the 10% that could be obtained from the Grail: ‘Summon Heroic Spirit’.

Once a Heroic Spirit is summoned, the Mystic Code’s functions gradually change. The processor goes inactive, preventing further summons and becoming the Servant’s own Spirit Core.

A used, but well-preserved processor chip is a highly effective summoning catalyst. It can almost, without fail, enable the summoning of the same Heroic Spirit, or a Heroic Spirit with strong ties to the original inhabitant of the processor. As such, deactivated processor chips belonging to powerful Heroic Spirits are highly coveted.

Serial Number

Every S.E.R.V.A.N.T. frame comes with its own unique serial number inscribed onto their core during production.

Serial Number Naming Scheme

Every serial number is formed by four sections: Class, Origin, Death, and a Random Number Identifier.

For example, the Serial Number for the prodigious Servant, King Arthur, would be written as SBGB050169.

SB	GB	0501	69
Saber	Great Britain, their birthplace and origin of their legend.	Start of 6th Century, which is Arthur’s rumoured death date.	Two random digits created by the system. Used as unique identifiers in case two Servants share the same class, origin and death.

Further examples are listed down below, but most serial numbers given to Servants abide by this standard. Certain Servants are given special serial codes, mostly unique identifiers that only owners of the central network can understand. They are usually given to ‘peculiar’ Servants that are worth paying special attention to.

Serial Number Examples

Serial Number	Servant
ARUR250033	Gilgamesh
LCIR000101	Cu Chulainn
RDMA032367	Alexander The Great
ASJP161220	Sasaki Kojiro

Serial Number Legend (Class)

Class
SB = Saber	AR = Archer	LC = Lancer	RD = Rider	AS = Assassin	CS = Caster	BZ = Berserker

Serial Number Legend (Origin)

Origin
Abbreviated Birthplace	FI = Fictional Origin	MY = Mythical Origin	DE = Deity/Divine Spirit Origin

Mana Upkeep

A Servant summoned within a S.E.R.V.A.N.T. frame has specific ways to manage their mana upkeep:

1. (Republic Frames Only) - Obtaining mana batteries that are designed specifically for S.E.R.V.A.N.T. Mystic Codes. They are commonly available, be it at convenience stores or supermarkets. Only Masters have permission to purchase them legally (See Magic-Mana Batteries).
2. (Republic & Church Frames) - Traditional mana transfer sessions.
3. (Church Frames & Post-bonding Republic Frames) - Mana sharing enabled by establishing a bond with a Servant (see Summoning & Bonding).

Unlike in the past, Servants in this setting cannot gather raw mana or ether from the environment itself. (see Magecraft).

Power Level

Regardless of how much mana a Heroic Spirit obtains, they are a far cry from any version of them that could be summoned from the Counter Force or the Throne of Heroes in the Old World. Due to the identical specs used by all of the mass produced S.E.R.V.A.N.T. frames, it could be said that most Heroic Spirits summoned through them have the same baseline ‘power level’ as each other.

Summoning a Servant

Once a S.E.R.V.A.N.T. frame’s core is activated, it will instinctively attempt to summon a Heroic Spirit. A successful summon results in the core morphing the cybernetic body of the Mystic Code into a facsimile of the Heroic Spirit that was summoned.

At this point, the Mystic Code is considered more Servant than golem and it becomes impossible to treat it as a conventional machine. The summoning is permanent and the processor goes inactive, making it impossible to summon a Heroic Spirit twice while using the same Mystic Code.

A Servant summoned via this method will retain all of its memories from the Throne of Heroes, along with the memories it obtained from the processor (what happened to humanity post cataclysm). A Servant will also realize the nature of its mechanical body, but most likely won’t do anything about it since it is no different than having a body purely made of Ether (in FSN) or Data (in Fate/Extra).

From here on, functions of Republic and Church frames begin to differ. Please refer to Republic & NHE Frames for a more detailed explanation.

Availability

Warning:

This section pertains to Republic Frames only. Church Frames are more limited in nature and can only be obtained privately. As such, their availability varies greatly depending on context.

Despite the prevalence of S.E.R.V.A.N.T. frames, they are still costly to obtain, both legally and illegally. Owning a unit is a hefty investment akin to owning a luxury car, and incidents such as stolen frames are rampant in poorer districts of nomadic cities.

Masters can either purchase a fresh S.E.R.V.A.N.T. frame to activate themselves, or they can go to auctions and bid on ‘prebuilt’ Servants summoned by other, more competent mages.

Aside from competitive environments such as Holy Grail Wars, Servants have fully integrated themselves into the average city life. Their purpose isn’t always stellar, sometimes reduced to being trophies for the wealthy or doing manual labour that keeps a city running.

Naturally, not all summoned Servants are content with their new status. Rebellious Servants are quite common, but the existence of the kill switch (Republic Frames Only) forces most of them to be complacent. Despite this, Heroic Spirits are still very much necessary for humanity due to the amount of threats that pervade the world.

Auctions

Many skilled mages are willing to summon Heroic Spirits for buyers in exchange for goods, wares or money. These buyers then put up the Heroic Spirits for sale on auctions, allowing any individual rich enough to purchase them, be it in person or online via the CWW.

These auctions are usually approved by Republic or the Neo Holy Empire and a license must be purchased in order to legally hold an auction. This doesn’t stop black market auctions from happening, however.
