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

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.
