Oberon

His true identity is not a Heroic Spirit from Proper Human History, but a Servant born in Faerie Britain. He is a doomsday device that curses the world, born from the Abyssal Wyrm of Fae British legend said to return all to nothingness. The name Oberon was simply taken from Proper Human History.

His name in the Faerie Kingdom is Vortigern, and he shares the same name as King Vortigern, the tyrant who led Britain to destruction by selling off the nation to various tribes.

Oberon the big liar. His existence and even his name are lies. When his true nature is revealed, he declares without a hint of shame, "I have nothing I like," as the edges of his mouth curl upward.

...Obviously, this is a lie as well, since not a single thing he says is true.

"My True Name? Yeah, it's also Vortigern. So what? Don't you remember me saying that having more names, the better?"

There is a forest called the Autumn Woods, located in Wales, on the outskirts of Faerie Britain. It is inhabited by powerless insectoid faeries, or small fairies whose innocence and low intelligence made them unable to assimilate with the faeries of Britain who had taken to mimicking human society. Faeries who felt out of place in Faerie Britain, faeries who fled because they were bullied, and faeries who were persecuted for simply existing and reviled for "spreading poison" also gathered in this forest, and ended up dying helplessly. It was in this forest inhabited by "those who had nowhere else to go", or "those who were hated and died in obscurity"...that the Vortigern of this age―Oberon―emerged.

Oberon is a Servant born from the British Isles, as well as being a doomsday device (Vortigern) created by the British Isles. He appeared as numerous forms of malice in the past (the mors king being one of them), and led the British Isles to destruction. Once Morgan's Era of the High Queen began, he was thwarted twice, which led to the creation of "Oberon."

He is popular with Britain's faeries because of his resemblance to the Wind and Wing clans, the most noble of all clans in Faerie Britain, but he is not a faerie at all. In fact, he is a single insect (ignobly) born from the emotional excrement embodying the island's revulsion for living things, disgust that a long-dead history has continued for over 10,000 years, and the desire to eliminate everything that lives on the island as well as all traces of the island itself.

In an ironic turn of events, when the British Isles produced the ancient faerie Oberon, his Spirit Origin overlapped with that of the Fairy King Oberon thanks to the influence of Proper Human History that Morgan brought in. This is how his purpose as a doomsday device and his nature as Oberon the King of Faeries are able to coexist.

A beautiful young man with hair dark as the deepest shadow, sunken blue eyes, and sharp bony limbs. He is evil incarnate, the very image of a fairy-tale villain—a prince of darkness. His every word and action is a lie. He claims his life's purpose is to watch humans fall to ruin, but there's no way of knowing whether he is sincere in this or not. He does not hold others in such contempt and work always to bring misfortune on them because he loves only himself and wishes only for his own happiness. Rather, he finds everyone and everything utterly revolting. He has neither love for others, nor for himself.

As Oberon's Fae Eyes see the truth, he looks down on everything he sees and conceals the sheer disgust that wells up from the very depths of his heart with an elegant smile. His every expression is a performance, and his lies, though without flaw, are nonetheless not wholly fabrication. There is a genuine aspect of himself that could live this way if he so chose. Yet, as he is cursed to have all that he says be a lie, any truth in his words or deeds is rendered meaningless.

He will never harbor love for any living creature. To Oberon, humans and faeries are "meaningless, grating on the eyes, disgusting yet seemingly content" objects to be eliminated. Because he will never be able to feel happiness himself, he is irritated and unable to comprehend why other living things can effortlessly achieve happiness simply by living.

『Lie Like Vortigern』

Rank: EX

NP Type: Anti-World

Range: Unlimited

Maximum Targets: Unlimited

Eye of a Dream Falling Yonder.

The true form and Noble Phantasm of the Oberon brought into existence by Faerie Britain. He transforms into the hollow insect tasked with Britain's destruction—the evil dragon Vortigern—and he swallows the entire world with his giant blender-like mouth and esophagus (hollow) to bring it to ruin. It doesn't kill the targets, but rather serves as a path to another world which plunges them into an abyss devoid of any light.

Ending of Dreams: EX

The terminal dream. A skill that enhances a single Servant. The affected Servant's abilities are augmented to an extraordinary degree, but at the end of the turn, all effects expire and the target falls into an eternal slumber.

...Those who lose their dreams shall never regain the will to awaken back to reality.

Fae Eyes: -

A form of vision, innate to faeries, which "converts the world." It is different than the Mystic Eyes some humans possess. These are said to be the eyes of greater faeries who can pierce through all falsehoods and reveal the truth, and they show Oberon the malice, flaws, and inner nature of intelligent beings.

Anti-Humanity: D

The power to put a hold on all things humanity produces and the laws that work in humanity's favor. Normally the Beast class possesses this skill. Despite being unable to hate or hold a grudge against humanity, Oberon's eagerness and desire to eradicate humanity is as instinctive as breathing. This enabled him to acquire the same skills as the Evils of Humanity after eons of deception and biding his time. Simply put, it is a form of malice that subtly seduces the direction (or the mood) of the target's hearts and minds toward baser, more evil things.

Furthermore, he is on profoundly poor terms with Merlin, another resident of the dream world. Oberon rejects all support and aid from Merlin. This rift was born of their different attitudes toward your tale, and Oberon dedicates almost all his powers of disguise to deceive Merlin. Thus, Merlin is unable to perceive Oberon, and whenever someone speaks to Oberon through Clairvoyance, Merlin sees that person as simply speaking to themself.

Midsummer Night's Dream: EX

The curse Oberon has been inflicted with ever since his inception.

"While these visions did appear; / And this weak and idle theme, / no more yielding but a dream."

One of the world's most famous fairy plays, "A Midsummer Night's Dream," closes with this soliloquy, which is also representative of Oberon's nature. In human history, the Fairy King's every word and action have been labeled as lies, cursing him to forever be unable to speak truth.

"Those damn bastards. I'll destroy them all one day."

Oberon's aggression stems neither from jealousy, nor from hatred, but rather from his love for Titania. However, he will never admit to this aloud.
