Caster (Fate/Crossover - Jonathan Strange)

**Caster** (キャスター, *Kyasutā*) is the servant of ??? in the ??? Holy Grail War.

## Profile

### Identity

Caster's true identity is **Johnathan Strange**, one of the two main characters in Jonathan Strange & Mr Norrell. He is one of the two magicians who are foretold to appear in England in order to revive magic. He becomes Mr. Norrell's pupil, then his rival.

### Personality

Jonathan Strange is a very creative, but distracted and undisciplined kind of person. He is spontaneous and sometimes doesn't follow through, as seen in the winding road he took in choosing a profession and the way he decided upon magic.

This also applies to his magical abilities, which he can't always control and not even understand most of the time: he describes his doing magic as a composer who instinctively knows which musical note needs to follow.

In the field of magic he often goes very far with not enough thought of the consequences and completely without a plan (he resurrects the Neapolitans knowing that he has no clue what to do after, how to make them dead again) and he is somewhat prone to recklessness (ex: he attacks Norrell's house in a burst of anger, getting himself arrested and confirming the preexisting rumours that he turned into a villain).

His personality is somewhat the antithesis of Mr. Norrell's: Jonathan Strange is the overflow, the excess, inborn talent with little grounding in learning - with its positive sides and downsides; Mr. Norrell is the too disciplined shut-in, fearful of the outer world, hoarder of knowledge and learning, with its good sides and downsides, too.

He is compassionate and much less classist than the other characters: he recognises Childermass' talent and knowledge of magic when others don't or won't because he is a servant. He (in the movie, in the book not as much) wants everybody to have access to knowledge about magic, including women.

He is loyal and very much in love with his (in the 1st episode girlfriend, then) wife, Arabella and, when she is kidnapped with spells that fake her death, he tries everything to bring her back to life, then, after finding out she is alive, he doesn't hesitate to put his health and life in danger and he eventually succeeds in freeing her.

## Abilities

Within the series- specifically seen inside of the first episode- Jonathan discovers his magical prowess shortly after being offered two spells written on a piece of parchment. This is where his occupation and journey as a magician begins. Compared to other magicians his magic seemingly has no limitations, allowing him to cast various spells that surpass the understanding and imagination of more experienced magicians like Mr. Norrell as well as Jonathan himself.

* Scrying

In the first episode, Strange performs one of the spells, written on the parchment he received named as "A spell to show what mine enemy is doing presently". Strange used a small mirror with the stems of wilted flowers placed parallel on both sides, as the spell required "something dead" and a reflective surface. He then drew a circle in the center of the glass and "quartered it". Though he was probably not expecting a resulting effect, the reflection inside of the mirror changed to show the inside of Mr. Norrell's study rather than the reflection of the dining room he and a few other characters were present inside of at the time.

- This enchantment would soon be proven useful to Jonathan as it allowed him to use other reflective mediums such as a bowl of water to see people and witness situations remotely. It also allowed him to hear sounds from where the mirror showed.

* Reflective dimensional transposition

An ability that allowed Jonathan to switch the reflection of a object and the actual physical form of the object itself. The effect caused the reflection of a paper to appear in the real world as an intangible and backwards visage while the actual paper resided inside of the mirror. A witness to this feat was Mr. Norrell who claimed that it was a magic that he had never seen before.

* Dreamscape Entering

An ability that allowed Strange to enter and communicate inside of the same dream shared between him and Jonathan Segundus.

### Skills

#### Class Skills

* Item Construction (C Rank): Creation of powerful magical artefacts is possible.

* Territory Creation (C Rank): Creation of a Magus workshop is possible.

#### Personal Skills

* Magecraft (B Rank): "I met a man under a headge. He said I was Magician." As one of two Magus directly responsible for resurrecting British magic following a 300 year decline, Caster could truly be said to one of the most important Magus of his era.

* A Dose of Madness (D Rank): "My tutor says that magic cannot cure madness. Apparently, the Aureates found it a magically useful affliction." While active A Dose of Madness provides a significant boost to Casters magical abilities; trading precision, stability and sanity for raw power and scale. It also grants him the ability to ignore illusions in the way only a madman could along with limited protection from mental interference.

* Disengage (Mirror Door) (D Rank): During his time as a Magus Caster developed a limited amount of skill with the Second Magic and utilised it to seemingly vanish (or appear form nowhere) on several occasions. Caster must be within one meter of a reflective surface to use this skill.

### Noble Phantasm

#### **The Black Tower; "The Raven Kings Call"**

While in reality it was a spell cast upon Caster by another being, The Black Tower was believed by the general populace to be a manifestation of his decent into madness. Once activated The Black Tower creates a bounded field that takes the form an enormous vortex of darkness centred on Caster. While ordinary folk may pass in and out of its boundaries with little, if any, ill affect humans with active magic circuits will find themselves unable to leave once inside. As they now share Casters curse. Those afflicted will have their mana and life force drained until their body fails. It is a slow but virtually inescapable death.

Though caster himself is susceptible to the tower's effects and could not ordinarily leave, he can move the tower by using a mirror to travel to Lost Hope and return to the world in a different location. The tower will then relocate itself to wherever he reappears.
