First introduced in "Faerie Round Table Domain: Avalon le Fae," this Servant was summoned to Britain to defeat Morgan, the ruler of Faerie Britain. Oberon has been known in the British Isles since ancient times, but this version strongly resembles his portrayal in Shakespeare's "A Midsummer Night's Dream."
He is fairly capable in combat, but excels in intelligence gathering and combat support, risking life and limb to ensure the success of Chaldea's mission. This trusty faerie king puts his heart and soul into securing Britain's true future.
A beautiful young man with gentle blue eyes, silver hair, and pale skin. He's mild-mannered, sprightly, and a kind-hearted pacifist. His judiciousness makes him meticulous and careful in planning and executing strategies, but he never misses the exact right moment to make his move. He approaches situations bullishly and aggressively (some may see it as savagery).
He resembles a perfect prince of light straight out of a fairy tale. Simply put, he's a cunning main character, as proven by his mature smile but boyish behavior, or the fact that he is like an innocent visionary but possesses the authority and power of an adult. He is educated but not patronizing, idealistic but not militant, weak but not dependent on violence. He is the greatest prince of light of all faerie history, but he will not take a wife.
"I like being happy. Just like bugs require clean water, faeries can't live without being happy."
SPOILER: He is not, in truth, a Heroic Spirit from Proper Human History, but a Servant born in Faerie Britain. He is a doomsday device which curses the world, born from Faerie Britain's legendary Abyssal Worm, which is said to return all to nothingness. The name Oberon was simply taken from Proper Human History. His name in Faerie Britain 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 liar. His entire existence, even his name, is lies. When his true nature is revealed, he declares without a hint of shame, "There is 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.
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.
