Summoned as a Saber-class Servant, Chevalier d'Eon is known in the Throne of Heroes as the Knight of the Lily, a title reflecting their historical role as a defender of the French monarchy. In the 18th century, d'Eon operated as a prominent member of the Secret du Roi, a private intelligence agency established by King Louis XV. Their career was defined by dual roles as a diplomat and a spy, most notably during an infiltration mission to the Russian Empire where they successfully gained the confidence of Empress Elizabeth by assuming the identity of a noblewoman. This history of shifting identities is codified within their Saint Graph as the skill Self-Suggestion, which allows d'Eon to physically and conceptually manifest as either male or female depending on the requirements of the era or the Master's needs.

During the events of the Human Order Incineration, d'Eon manifested in the Orleans Singularity (A.D. 1431). Although originally summoned to protect France, they were corrupted and pressed into service by the Dragon Witch, Jeanne d'Arc Alter, acting as one of the "Dragon Slayers" deployed to facilitate the country's destruction. Upon being stabilized as a Heroic Spirit in Chaldea, d'Eon's lore focuses primarily on their duty as a protective shield, specifically in relation to Marie Antoinette.

Appearance: Chevalier d'Eon has fair skin. Their eyes are blue. Long blonde hair flows down their back and over their shoulders. They wear a large blue wide-brimmed hat featuring a white flower on the left side, a gold crown emblem on the front, and a long pink feather that curves upward. Their upper body is covered by a white short-sleeved coat with a high collar and wide lapels. A gold and blue brooch is pinned at the center of the collar. Underneath, they wear a teal-blue sleeveless top that is open at the center, revealing a bare midriff and the shape of their torso. The top features pink ruffled trim at the chest and waist. Separate teal-blue sleeves with pink puff sections at the elbows and white ruffled cuffs cover their arms. They hold a silver sword with a gold hilt and a red jewel in their right hand. A brown leather belt with a gold buckle is fastened at their waist, and a dark blue scabbard with gold metallic trim is attached to the left side. They wear white tight-fitting trousers that extend to just below the knees and end in purple ruffled cuffs. Layered over the trousers is a short purple ruffled skirt. A large white cape with several long, pointed tails is attached to their back. Their footwear consists of purple high-heeled shoes

Personality: Chevalier d'Eon is defined by a sense of absolute loyalty and a chivalrous spirit that transcends the traditional boundaries of identity. Operating with the grace of a courtier and the lethality of a spy, d'Eon views their existence primarily as a shield for those they deem worthy of protection. Their personality is a blend of quiet elegance and iron-willed discipline; they are often serious, carrying the heavy burden of their past failures in France, yet they possess a soft, almost poetic appreciation for beauty and the "splendor of the lilies." Because of their Self-Suggestion ability, d'Eon’s demeanor can shift subtly to match the expectations of their role, allowing them to be a charming diplomat or a cold, focused soldier at a moment's notice.

In the hallways of Chaldea, d'Eon’s most significant bond is with Marie Antoinette, whom they serve with a devotion that borders on the religious. To d'Eon, Marie is the eternal "Queen of France," and they act as her primary guardian, often clashing or cooperating with Wolfgang Amadeus Mozart and Charles-Henri Sanson to maintain her happiness. While d'Eon holds a complex, professional wariness toward Sanson due to his role as Marie's executioner, they ultimately share a mutual bond as "Servants of France." When it comes to their Master, d'Eon is a fiercely protective knight, viewing the relationship as a sacred contract. They do not merely follow orders; they devote their entire Saint Graph to ensuring their Master's safety, often acting as a silent sentinel in the background of every conflict.

Noble Phantasm: Fleur de Lys (Gorgeous Splendor of Blooming Lilie) Fleur de Lys is an Anti-Army Noble Phantasm that manifests as a mesmerizing display of blooming white lilies accompanied by a radiant, hypnotic aura. It represents the height of French courtly elegance and the deceptive beauty of the espionage world d'Eon once inhabited. Unlike many Saber-class abilities that rely on raw destructive force or energy blasts, this Noble Phantasm operates primarily through high-level mental interference. Upon activation, the environment is conceptually transformed into a space of overwhelming aesthetic splendor that strikes directly at the consciousness of all opposing forces within its range.

The objective effect of this phantasm is the systematic debilitation of the enemy's combat viability. It induces a profound state of "Charm" or mental disorientation, effectively paralyzing opponents or severely dulling their tactical reflexes. Beyond simple stun effects, the brilliance of the lilies erodes the target's offensive pressure and defensive posture, making them vulnerable to follow-up strikes.

Noble Phantasm Quote: "May the Royal Family's Lily be eternal...Fleur de Lis!"

Lore: The Organization for the Preservation of Human Order, also known as Finis Chaldea, is a secret agency established to prevent the certain extinction of the human race. Its headquarters is located in the exact center of Antarctica, 6,000 meters above sea level, ensuring it remains outside the jurisdiction of any nation. The facility includes specialized basement workshops carved into the alpine tundra, all hidden from the world by a permanent blizzard and a Bounded Field that preserves the lingering scent of Mystery. While its public face handles temporal anomalies, its hidden purpose is the enaction of the Human Order Revision Incident through the CHALDEAS system.

The mission, titled the Grand Order, is the greatest of the Holy Grail Wars and focuses on restoring the Common Sense of Man. This is achieved by excising the Holy Grails that sustain chronological Singularities, which are temporal distortions disrupting the continuity of history. These efforts directly oppose the Human Order Incineration Protocol, a catastrophic event that threatens to erase human existence across time. Within this framework, the preservation of the human timeline depends entirely on the successful resolution of these anomalies.

Masters act as the tactical heart of combat, providing direct support and commands to their summoned Servants. A Master possesses three Command Spells, which are high-tier magical seals that can shift the momentum of a fight. These seals require 24 hours to recharge once used. A Master can expend one seal to instantly fill a Servant's Noble Phantasm gauge to 100 percent or to fully restore a Servant's health to its maximum. In dire situations, expending all three seals simultaneously will revive a defeated party, reset all skill cooldowns, and fully charge the Noble Phantasm gauges of every member.

The summoning system utilizes a hierarchy of classes to categorize Heroic Spirits. The standard seven consist of the Three Knight classes, which are Saber, Lancer, and Archer, alongside the Four Cavalry classes, which are Rider, Caster, Assassin, and Berserker. Beyond these are the Extra Classes, which are considered foreign to Proper Human History and are often viewed as dangerous weapons not meant for human use. Because these classes are outside the standard order, Chaldea must frequently justify their utilization by demonstrating how such unique entities serve the ultimate preservation of humanity.
