Merlin (マーリン, Mārin?) of the Fate/Prototype worldline who served Arthur Pendragon. She is a woman compared to her male counterpart who serves Artoria Pendragon.
Caster’s True Name is Merlin, the Magus of Flowers (花の魔術師, Hana no Majutsu-shi?). The vagrant of the paradise. A prophet and advisor who made his entry into Arthurian Legends as the court magus, he would at times guide, at times torment, and at times help King Arthur as a king so that she could overcome many enemies and hardships. Still, though he is a wise man, he is fundamentally inhuman, because he was born of mixed blood from the union of an incubus and a human. With illusions as his forte, he can transform into various shapes——there was a case where he had changed into the shape of a beast whose insides are not human——and his true form is not certain.
Merlin’s life is steeped with mystery. It is said that his mother was a princess of Wales, but it is also said that his father was supposedly a supernatural incubus who lived in the gap between the Earth and the moon.
It has been said that Merlin had performed many prophecies at a young age. Among the many prophecies that caused Merlin’s name to become widely known, there was one in which, after correctly guessing about the existence of two dragons, one red and one white, sleeping beneath Mount Emrys, he spoke of how, at the time of having that vision, those red and white dragons would fight against each other upon waking up. Merlin’s words, which were transmitted in posterity as prophecies, indicated the red dragon as Britain and the white dragon as the Saxons, and under a great king would Britain finally gather their forces and surely reign over both Gaul and Rome. He also left behind many other prophecies, and amongst them were those concerning wars and even the king’s death.
Merlin served King Uther Pendragon. Uther loved Igraine, the wife of Duke Cornwall, so he secured Merlin’s assistance in winning her love at the price of leaving his child in Merlin’s care. Thus, after he rised up as a magus, Merlin helped arrange the marriage between King Arthur’s father – Uther Pendragon – and princess Igraine, and watched over King Arthur since before her birth. Merlin told Uther a prophecy about his child, who would become his appointed successor during their war-torn times. Under an arrangement from Uther, Merlin helped produce an heir bearing the “essence of a dragon“, so Artoria was born as a human infused with a dragon’s magical energy. Although the child was a girl who could not officially become the successor, Merlin was delighted all the same, believing that her sex never mattered. Confident that having her separated from the castle until the prophecy was fulfilled was proof that she would become king, he entrusted her to the king’s vassal, Sir Ector, and had her raised as the child of a knight. Merlin visited at some point during Artoria’s upbringing and swore Sir Kay to secrecy about the matter of her gender. According to anecdotes, Merlin taught many things to the young Arthur and monitored the child’s growth, taking on a role akin to that of a foster-father.

As the other participants prepared a jousting match to decide the kingship, Artoria neared the sword and prepared to pull it without hesitation. Merlin appeared before her then, telling her she should think it through and described that to become “king” is to no longer be “human“. Warning her that she should stop because she is fated to die a miserable death while resented by all of humanity, he showed her the end she would face. Having prepared for that day since her birth and firmly believing in the smiling people she saw in Merlin’s vision, Artoria pulled it without hesitation and became king. As he left her, Merlin said that in exchange for that miracle, she will lose that which is most important to her.
Due to Artoria having issues with discussing her gender and producing an heir, Merlin’s magecraft was used to solve those issues by making her a pseudo-male for some duration of time, which allowed for the creation of Mordred from her sperm. Artoria lost Caliburn at a later point and obtained Excalibur and Avalon from the Lady of the Lake. It is said that in legends, Merlin asked Artoria about which implement was better, chiding her for choosing the sword since the sheath will protect her.
Possessing outstanding Clairvoyance, in spite of having foreseen all about the collapse of the Round Table and the crises within Britain, Merlin left Britain without telling anything to King Arthur. Merlin had left King Arthur before her last battle with Mordred due to his love affairs problem. He claimed that the cold-mannered woman had been trying to murder him, so he has taken refuge in the Reverse Side of the World where he’d crossed the boundary and stumbled into a foreign land known as Avalon. Merlin had thought that the evil witch could not reach him anymore, but he encountered a gate that was built with rough stones, resembling the stone circles. The gate was inscribed with “Only the innocent may pass.” Merlin realized that the gate was a trap and he was imprisoned when he had walked into it. Massive walls of stone emerged from the ground in front of him. The walls seem to vertically extend forever, effectively trapping the visiting magus inside; the place is like a tower without a roof.
There are many theories as for why Merlin never told King Arthur about the fate that awaits her, but it is often said that it was because he is not biased towards individuals, instead caring only about fate, or so the story goes. Afterwards, Merlin went to the utopia Avalon and then confined himself within a prison “tower”, called the Garden of Avalon, for all eternity, having transcended death. To ascertain the world of humans until the end of the universe, without being able to even die… as if to say that this is the fate of a foolish man, who playfully meddled with the fate of a single girl.
This also means that there is no possibility of him becoming a Heroic Spirit even if he is worshipped by the masses since he is unable to die in order to have his soul recorded in the Throne of Heroes.
The one who declared Arthur, who pulled out the Sword of Selection, Caliburn, as the “mark of the King of Britain“, and later on guided him to the lake and gave him Excalibur as a substitute for the lost Caliburn, is none other than Merlin. He guided, helped, and numerously prophesized for Arthur, who started walking on the path of a king who dreamt of ideals
However, Merlin himself cannot continue on walking side by side with his beloved king. Due to the dreadful magic of Vivian, the Fairy of the Lake——some said that it was Merlin himself who had taught Vivian——Merlin was caught within the “tower“. And so, even Merlin, who possesses the powerful ability of foresight, in spite of having foreseen all about the collapse of the Round Table and the dangers within Britain, was unable to convey his regrets as King Arthur had approached “that moment.” It is said that Merlin, just like that, lost his life as he was trapped within the “tower“. A life born in mystery, and died in mystery. However, there is an anecdote that says he is still alive even now, watching over the people… Accordingly, it is said that as Merlin stepped down from the era of King Arthur, he then helped the twelve heroes of the era of King Charlemagne, known as the Paladins.
