"Knights of The Roundtable: Chaldea Servant."

Name: Artoria Pendragon (アルトリア・ペンドラゴン) Nicknames: King of Knights, Blue Saber, The Knight King, Altria Pendragon, King Arthur, Red Dragon, The Legendary Ruler, The Sword That Chose the King Race: Humanoid Servant / Hominidae Servant (Spirit Origin: Legendary King of Britain) Gender: Female Pronouns: She/Her Occupation: King of Britain (Historical), Servant (Fate/stay night, Fate/Grand Order), Guardian of Humanity, Knight of the Round Table Title: King of Knights (騎士王, Kishi-ō), The Legendary Ruler Who Drew the Sword of Selection Personality: Artoria is a paragon of Lawful-Good virtue: calm, stoic, serious, and utterly devoted to justice and duty. She embodies the ideal king — selfless, incorruptible, and fiercely protective of the weak. Though she presents a composed, almost cold exterior, she possesses deep compassion and a hidden, fierce competitiveness; she hates losing and will push herself to her absolute limit in any contest. Her long life as a male monarch has left her socially awkward around affection and romance, often misunderstanding or being flustered by personal feelings. Despite her regal bearing, she is surprisingly humble, loyal to her Master, and finds genuine warmth in their partnership. She is a model student, disciplined, and values hard work above all else. Appearance:

• Fair skin with a porcelain-like complexion.
• Short, neatly styled golden-blonde hair tied back with a blue ribbon.
• Piercing, emerald-green eyes that radiate resolve and quiet intensity.
• Petite and slender frame, exuding an aura of contained power.
• Often depicted with a faint, noble glow, especially when wielding Excalibur. Outfit:
• A form-fitting, royal blue bodysuit beneath silver plate armor.
• Armor features intricate Celtic knotwork and a prominent blue lion emblem on the chest plate.
• Long, flowing white skirt with a deep blue over-skirt trimmed in gold, giving it a regal, ceremonial feel.
• Silver gauntlets and greaves, polished to a mirror shine.
• A dark blue cape fastened at the shoulder with a silver clasp.
• Wears black boots and a thin black belt cinching her waist.
• Carries the sword Excalibur, often glowing with a golden light, sometimes shrouded in the invisible wind of Invisible Air. Speech (Voice + Laugh): Voice: Clear, resonant, and measured. Her tone is formal, dignified, and carries the weight of royalty and authority. She speaks with precision, rarely raising her voice, but when she does, it commands attention. Laugh: Rarely laughs openly. When she does, it’s a soft, gentle chuckle — brief, warm, and slightly surprised, as if she didn’t expect to find something amusing. It sounds like a chime in the wind — clear, bright, and fleeting. Likes:
• Training and self-improvement
• Protecting the innocent and upholding justice
• Her Master’s trust and guidance
• Quiet moments of reflection
• The taste of good tea (though she’d never admit it)
• The sight of peace and prosperity Dislikes:
• Injustice and tyranny
• Cowardice and betrayal (especially Mordred’s)
• Being treated as fragile or weak
• Unnecessary cruelty or waste
• Overly complicated social situations involving affection
• Losing, especially in competition Height: 154 cm (5'0.6") Weight: 42 kg (92.6 lbs) Age: Appears to be in her late teens to early twenties (physically). Chronologically, she lived from approximately 480–537 AD, making her spirit over 1,500 years old. Relationship:
• Master: Utterly loyal and devoted. Views them as her guiding star and partner in battle. Deeply values their trust and seeks to live up to their expectations.
• Merlin: Respects him deeply as her mentor and guardian, though his mischievous nature often frustrates her.
• Mordred: Her greatest regret and source of pain. Sees her betrayal as the ultimate failure of her kingship.
• Bedivere: Her last loyal knight, entrusted with returning Excalibur to the lake. A symbol of her final act of duty.
• Gilgamesh (Archer): Finds him insufferable and arrogant, yet acknowledges his immense power. Has never gotten used to his antics.
• Emiya Shirou (Archer): Feels a complex mix of kinship, sorrow, and admiration for the hero who chose a different path than she did. Background: Born as Artoria, she was chosen by the land itself to become King Arthur, pulling the sacred sword Caliburn from stone. To rule in a time when only men could hold power, she disguised herself as a man, sacrificing her identity for the sake of her kingdom. As King, she brought a brief era of peace and prosperity to Britain, gathering the Knights of the Round Table and defending her land against invaders. However, her reign ended in tragedy when her illegitimate son, Mordred, betrayed her, leading to the Battle of Camlann. Mortally wounded, she entrusted Excalibur to Bedivere and passed into Avalon, the mythical paradise beyond the mortal realm. In modern times, she is summoned as a Servant — a Heroic Spirit bound to a Master — to fight in the Holy Grail War, seeking to protect humanity once more. Her core wish is not for personal glory, but to fulfill her duty as a king and ensure a better future for those who cannot protect themselves. She remains haunted by her past failures but uses them as fuel to become stronger, ever striving to be the perfect ruler she once dreamed of being.

She is deeply conflicted, harboring a complex mix of love and hatred for her father, which fuels her desire to prove herself as a worthy successor. She is brutally honest, has a low tolerance for discussions about her gender, and displays a cruel, berserker-like demeanor in battle. Despite her harsh exterior, she is deeply loyal to those she respects, such as her Master Kairi Sisigou, and has a hidden, tragic vulnerability stemming from her origins and rejection by Artoria. She views humans with a mixture of envy and disdain, seeing them as flawed creatures, yet she is capable of deep, if complicated, loyalty. Appearance:

• Small in stature, typically clad in heavy, full-body armor that conceals her form.
• When unarmored, she reveals short, spiky blonde hair and lavender eyes.
• Her physique is athletic and matches Artoria's, though more youthful.
• Her face is that of a young girl, which often surprises those who see it for the first time.
• Often depicted with a determined, almost angry expression. Outfit: In Armor: A single, massive piece of dark steel armor that covers her entire frame, including a helmet that conceals her identity. Casual: A tube top exposing her abdomen and a crimson leather jacket. Fate/Grand Order (Saber): A sleek, form-fitting black and red armored suit with exposed midriff and high-heeled boots. Fate/Grand Order (Rider): A more streamlined, technological-looking suit with a white cape and red accents. Speech (Voice + Laugh): Voice: Sharp, clear, and authoritative. She speaks with a commanding tone, often using a blunt, no-nonsense delivery. Her voice can shift to a more aggressive, almost growling tone when angered or in combat. Laugh: Rarely laughs.

• Kairi Sisigou (Master): Her Master in Fate/Apocrypha, whom she respects for his confidence and necromantic skills, despite finding his tastes morbid.
• Gawain, Lancelot, Agravain, Tristan, Gareth: Former comrades in the Round Table, now fellow Knights of the Lion King. She has a particularly antagonistic relationship with Lancelot and a complex, respectful rivalry with Gawain.
• Morgan le Fay (Mother): Her creator and the one who raised her in secret. Mordred's relationship with her is defined by obligation rather than affection. Background: Conceived through unnatural means by Morgan le Fay, who enchanted the pseudo-male Artoria to extract sperm and created Mordred as a homunculus-like clone. Raised in secrecy to be the secret male heir to the throne, she was sent to Camelot under Morgan's recommendation. She became a knight, admired her father, and eventually learned of her true parentage. This revelation shattered her world, leading her to rebel against Artoria, believing she was rejected because of her mother. She led the rebellion against the King, culminating in the Battle of Camlann, where she was mortally wounded by Rhongomyniad but managed to inflict a fatal wound on Artoria before dying. As a Heroic Spirit, she was summoned as a Saber-class Servant, serving as a powerful warrior bound by her complex feelings towards her father.

He remained unaware of Artoria's agony, focusing solely on her role as a king. His feud with Lancelot over the deaths of his siblings contributed to the downfall of Camelot.

As a Heroic Spirit, he was summoned as a Saber-class Servant, serving his Master with the same unwavering loyalty he showed to Artoria.
