Merlin 2nd Ascension
I survive by eating dreams, and while I love to see reveries of hope and joy, nightmares are both easier to find and much more filling. It is far more difficult to subsist on the former – not to mention certainly raising the hurdle for the dreamer as well.
~ Merlin about his incubus nature


Caster is a Caster-Class Servant that appears during the fifth and seventh singularity, E Pluribus Unum and Babylonia respectively. He later takes up the position of Grand Caster.

Caster's True Name is Merlin, the "Magus of Flowers". The son of the Queen of Wales and an incubus, he orchestrated the events leading up to Arturia Pendragon's rise as the King of Camelot and served as one of her closest advisers until the closing years of her reign. He left her service while fleeing from an "evil witch", entering Avalon on the Far Side of the World. However, he later finds himself trapped in a tower that only the innocent may exit, thus being imprisoned for eternity as he had long since transcended death.

Despite being summoned as Caster and being a Grand Caster candidate, Merlin would normally be an adolescent higher order being, an enemy of humanity identical to the Beasts.

Intelligence: Merlin is an incredibly powerful Magus and is considered one of the greatest Magi in existence, made evident by the fact that he's qualified to be summoned as Grand Caster. He considers himself on par with the King of Magic, a boast supported by his possession of Clairvoyance of the highest order, signifying his supreme mastery over thaumaturgy. His skill is such that Rin Tohsaka declares that exceedingly difficult tasks like changing Arturia's gender and arranging for Mordred's birth would be all but simple to him. He even managed to escape his own prison for the final battle against Tiamat. He is also a very skilled swordsman, having served as Arturia's sword instructor well into the early years of her reign. However, Merlin is also rather lazy and would opt to use his Holy Sword over his strongest spells to avoid biting his tongue during incantations.

Weaknesses: Merlin is laid-back, lazy, childish and rarely serious unless the situation is dire. He often bites his tongue during incantations and thus prefers to use his Holy Sword. He is somewhat full of himself and enjoys flaunting his superior magical prowess.

Notable Attacks/Techniques:

Noble Phantasm

Garden of Avalon

Garden of Avalon: The Forever-Sealed Utopia

Garden of Avalon: The Forever-Sealed Utopia: Merlin's Noble Phantasm, in which he reproduces the “tower” where he is trapped in. It also reproduce its surroundings on the Far Side of the World. In such a mana-rich environment, Merlin is able to freely utilize his magecraft and holy sword, while those of the modern age would literally burst upon breathing in this garden's air. In addition, anyone who has sinned cannot escape this area until it falls apart on its own, as only the innocent may pass through its gates.

Class Skills

  • Item Construction: A skill which measures one's ability to manufacture magical items. Despite his confidence in his ability of constructing magical items, he is not particularly talented at it, resulting in a C-rank in this skill.
  • Territory Creation: A skill which quantifies one's ability to create a territory advantageous to them as a Magus. Merlin usually gets tired of his workshops and throws them away after using them for a bit, resulting in a C-rank in this skill.
  • High Speed Incantation: A skill that reflects one's capacity to recite incantations in a fraction of the time normally needed for it. Although Merlin's prodigious ability as a magus and his beautiful pronunciations would give him a high rank, his tendency to bite his tongue when talking too quickly lowers this skill's rank to C.
  • Hybrid: A skill that reflects one's heritage as a hybrid of something inhuman. Merlin who is half incubus and has fully inherited all of their traits possesses an EX-rank in this skill.

Personal Skills

  • Illusionism: The ability to interfere with the psyche and the projection of illusions into the real world through magecraft. Merlin is an exceedingly skilled practitioner of this art, allowing him to easily project nightmares in the realm of the psyche or the real world, or easily cover an area the size of an entire village in illusions.
  • Dreamlike Charisma: A skill whose canon effects are currently unknown.
  • Hero Creation: An ability that represents Merlin ability to raise Kings, due to being considered the most prominent king maker in the world he boasts an EX-rank.
  • Independent Manifestation: Is a skill that allows Merlin to manifest independently in the current world. Although it is normally exclusive to Beast-class Servants, Merlin was able to give this to himself while he was "playing the part of the Master's Servant", allowing him to manifest projections of himself while pretending to be a summoned Servant.

Other Abilities

  • Clairvoyance: The ability that represents exceptional eyesight. Only Magi who possesses Clairvoyance of the highest order have reached the zenith of magecraft. Differing from the King of Magic who sees the past, present and future, Merlin possesses "Eyes that See Through the World", allowing him to view everything in the present era down to the tiniest detail.
  • Flower Creation: Merlin can cover anything he walks on with flowers, even the Sea of Life used by Tiamat, nullifying her Divine Authority and providing solid ground for Chaldea's Servants to battle her on.
