## Abilities

Lestari Elliwyn is considered a 'genius among the ordinary'. She scores a perfect score during her entrance exam at the age of 13 and finished her study in General Fundamentals within a year. Her Circuits are below average, yet she graduated from the famed El-Melloi Classroom and earned the Rank Pride at a very young age, a feat rarely seen even in the Clock Tower.

Lestari excels in fine control and efficiency of magical energy, as she is capable to unconsciously cast her bioelectricity spell inside her body all the time, something that noted to be harmful for careless magus. Her nickname, "Little Miss Gremlin", earned from her extreme proficiency on controling modernity and technology with her magecraft.

Prior to Fate/ConQUEST, she is competent enough to survive as a fugitive for 5 years.

### Magecraft

**Geomancy Recursion**

The Magecraft the Elliwyn practices is Geomancy, with each individual put their own spin on it. In the case of Lestari, she applies it as a means to control electricity. Using metal cards with 16 geomantic figures ascribed in it, she can create various electrical phenomena that compliment with the divination associated to each of the geomantic figures.

Geomancy is a popular school of Astrology, part of the seven forbidden Renaissance magecraft. Various magi that crave their name in general history have studied it, such as Aleister Crowley and Hermes Trismegistus. It boasts an easy to learn basic formula that almost anyone can learn it practically but doesn't offer a clear route to the root from how branched it was. The archangel Gabriel is invoked by simply using it, as there is a mythical connotation that Hermes learned geomancy from the angel, making it has high affinity to those with Water attribute.

Recursion is a mathematical logic to define a function with its own definition, having an infinite number of instances and values for the function to arrive. Processing a procedure goes through when one of the steps of the procedure involves invoking the procedure itself. Even if properly defined, a recursive procedure is not easy for humans to perform, as it requires some administration of how far various simultaneous instances of the procedures have progressed.

At first glance, using something as modern as recursion as a formula is impossible, but there is an old mythical basis for them. The term and definition of recursion is modern, but geomancy always employs random numbers as a way of divination. The 16 geomantic figures system employs lines that are represented as active and passive, all the divinations then are interpreted from these active and passive lines, transforming them into phenomenons. The very exact way a computer employs binary code 1 and 0 as the basis to run their programs.

The Elliwyn formulate their geomancy using the typical western way of divination, but with a twist. Traditionally, divination is done by recursing 16 random numbers as what's called the Mothers, Nieces, Witnesses, and Judge, which Judge is the final result of a fortune, the effect of the spell. The Elliwyn instead fixed the random process up to the point of Witnesses; making it as the formula, almost instantaneous in activation and main form of the spells. The downside is the user constantly uses their magecraft inside their body (Laetitia), making it a very wasteful magecraft on the hand of the unskilled.

### Mystic Codes

* **16 geomantic figures:** Metal cards ascribed with the 16 geomantic figures used primarily for divinatory geomancy. It is made primarily from materials that able to conduct electricity greatly such as silver. Its primary usage is to represent the 16 geomantic figures without manually gathering them from sand, allowing her to quickly casts her individual spells. She originally has more than one set, but the rest is lost and destroyed before Fate/ConQUEST. Provided with enough time and correct materials, she can craft these cards by herself.
* **Aeternus Algorithm:** A self-divining machine that Lestari invented and make her ranked Pride. In Candis' 721, it is used to cause a blackout in London for five minutes.

### Spells

* **Via** (Latin "The Way"): Generate electric bolt equal in firepower to the famed Gandr Shot.
It is considered bad of most things, but good with concerns of roads, travels, or journeys. Astrologically it is associated with Cancer and the waning Moon, and both its inner and outer elements are water. All the elements in Via are active, and as such the figure indicates change more than any other figure. Regarding the outcome of the situation being divined, it is neutral, unless change by itself infers a positive or negative result. This figure inverts any figure when added, giving it another meaning of change.
	+ **Via + Populus, sparkle:** Using both Via and Populus, exploiting the nature of their divination, the totally opposite differences between the figures, and her element Water as a conductor, she can emulate two opposing magnets to create a straight line of electricity. It is her go-to spell, as it is very versatile, as she can use it in various ways such as to flies around the field or to magnetizes debris and use them as thrown projectiles.
* **Populus** (Latin "The People"): Strengthen her own magecraft.
The figure resembles a bird's eye view of a group of people. The figure can mean that the outcome is based on the people of the situation, or represents a large number of people or peers. Astrologically it is associated with Cancer and the waxing Moon; both its inner and outer elements are water. It refers to a gathering or assembly of people and is very neutral, for though there may be a great deal of movement within the crowd, there is a very little effect on the crowd as a whole.
* **Laetitia** (Latin "Joy"): She mainly uses Laetitia passively to control her bioelectricity to keep her body warm and head cool, her mastery to passively control it without harm is proof that she is a true Elliwyn magus.
The figure resembles an arch, fountain, or rainbow. It is good in situations that concern potential, joy, or happiness. Astrologically it is associated with Pisces and Jupiter retrograde. It is ruled externally by water, but inwardly by fire. It is a positive figure for nearly all questions, representing fast situations and construction. It indicates upward motion, happiness, or joy.
	+ **Laetitia + Populus, blinds:** Exploiting the divination nature of both Laetitia and Populus, and the nature of her element Water as a conductor, she is capable of expanding the range of her bioelectricity controlling spell. However, the expanded range means her Laetitia is no longer cost less, nor does it is as potent as when she only uses it for herself.
* **Rubeus** (Latin "Red"): Exploiting its nature to stop a divination if Rubeus appears first, Lestari able to make an electrical booby trap and tune how damaging the electric zap can be. As it has an outer element Water that is the same with her Element, it's naturally more potent if activated from outside instead of inside.
The figure is an overturned glass; an inversion, meaning good in all that is evil, and evil in all that is good. The figure is considered so unfavorable that if it were the first in a reading, the reading would end. Astrologically it is associated with Scorpio and Mars retrograde; its inner element is ruled by Air, and its outer element ruled by Water. It represents passion, deception, violence, and vice.
* **Puer** (Latin "the Boy"): She mainly uses Puer as an attack that covers much more range than Via, but due to incompatible elements with her natural Element, it takes much more magical energy and less damaging than Via.
The figure is a representation of a sword or erect phallus and refers to male energies, primarily aggression and passion, but also war and male sexuality. It is bad in most cases, but good in situations where boys (in Antiquity and Medieval society) excelled: love and war. Astrologically it is associated with Aries and Mars. All elements are active except Water, the element of emotion; its inner element is air, but due to it being ruled by Mars, its outer element is fire.
* **Carcer** (Latin "the Prison"): Lestari use Carcer to create a circular electric barrier that defends her surrounding, it has a side effect to disturb detection like radar and sonar wave.
The figure is the outline of an enclosure, a link in a chain, or prison cell. It is usually bad in situations and denotes delays, setbacks, or bindings. Astrologically it is associated with Capricorn and Saturn retrograde; its inner and outer element is earth. It refers to immobility, and also thereby strength. Depending on the question it could indicate a restriction or a source of willpower. It is generally unfavorable but can be favorable in questions involving stability or security. It is associated with the knees and skeletal system of the body.
* **Cauda Draconis** (Latin "the Tail of the Dragon") The special nature of Cauda Draconis to stop divination upon drawing it allows Lestari to translate it into "the spell that stops". Meaning, she uses her electricity to shut down her opponent from the inner organ, which most of the case very fatal if she didn't hold back the output.
It is considered very bad in most situations, such that in older traditions if this was the first figure drawn the geomancy reading was stopped. It is only good in circumstances for ending or completing things, such as breaking up a relationship. It brings good with evil, and evil with good. It is associated with the malefic planets Saturn and Mars, and the astrological sign Virgo. Its inner and outer elements are both fire.
* **Tristitia** (Latin "Sorrow"): The nature of Tristitia generally representing bad fortune allows Lestari to exploit it as a powerful offensive spell. In the case of electricity, the most dangerous form of it is indeed natural thunder.
The figure resembles a broken arch or a stake being driven into the ground. It is bad in most cases and connotes sadness or mourning. Astrologically it is associated with Aquarius and Saturn. Tristitia is an unfavorable figure in almost all questions, usually representing pain and suffering. However, it is favorable in questions dealing with stability, building, or the Earth (such as agriculture). Its outer element is air and the inner element is earth.
	+ **Tristitia + Populus, blinds**: Exploiting the divination nature of both Tristitia and Populus, and the nature of her element Water as a conductor, she is capable of turning Tristitia into a homing thunder. With SFA Lancer's permission, she is also capable to redirect his Lightning Conductor Noble Phantasm.
* **Albus** (Latin "White"): Its nature as a peaceful reading and its ruling elements allow Lestari to make it a spell to deflect harms. It will magnetically fly around her and intercepts an upcoming attack automatically. But the card's small size makes it unreliable to use except when being used in a large amount.
The figure resembles an upright glass or goblet. It is good in most situations, especially with good figures in company, but itself is a weak figure. Astrologically it is associated with Gemini and Mercury; even though its inner element is water, its outer element is air. It represents peace, wisdom, and purity. It benefits beginnings and profit, or any situation where careful and deliberate planning is needed.

* **Recursion, activate**: The most basic way of Recursion, but can be applied in many ways. Effectively, it allows Lestari to repeatedly and quickly divines her formula by combining all possible combination of her geomantic cards. This can be considered as Lestari's magnum opus.
It is generally used as a type of cyber-divination, hacking by means of randomly trying every single combination of binary codes to match the machine's binary code to synchronize. Once Lestari synchronizes with a computer, she able to freely access and controls what are insides the machine and everything connected with it.
	+ **Rubeus Spiritus** (Latin for "Red Sprite") (Ruby: Great Ascension): A spell that summons red lightning. A Five-Count Spell.
	The principle behind the spell is similar to her usual brute-force hacking. The geomantic cards rapidly divines phenomenon until reaching the 'exact series of phenomenons' needed to fire the spell. But instead of synchronizing it with binary code, she uses the regular usage to actualize spells instead.
	The most important component is the geomantic cards Rubeus and Tristitia. Rubeus represents an overturned glass; an inversion, meaning good in all that is evil, and evil in all that is good. Tristitia resembles a broken arch or a stake being driven into the ground. It is bad in most cases and connotes sadness or mourning, and it invokes the angel Gabriel the most out of all the cards. Thus, Rubeus Tristitia means an inverted arch, upward lightning.
	It takes the form of a lightning elemental, and invoke the mythological sprite (spirit). Its appearance, which has a halo on the top (a side effect called Elves) emulates both the appearance of Mercurius and Gabriel. A red lightning that arches to the sky instead of to the ground, as if the spirit returns from Earth to heaven.
	While they can reach 100 km to the sky, they weren't made with attacking someone on space in mind. Lestari created the spell simply for her to have a large scale attack that able to be used once she inherits the full Crest. This spell is several times stronger and hotter than regular Tristitia, but its most dangerous aspect is its range and speed. It takes her a day after the New Japan invasion to finally grasp its true potential.
	Rubeus Spiritus can be categorized as familiars. But they can only be ordered for a simple command nor Lestari can gather information with them, so they are considered to be 3rd rate in this department.
