A legendary king of Britain. Also called King of Knights.
Altria is a childhood name and, upon being raised as a king, she began to be called King Arthur.
In a age when chivalry had lost its beauty, with a holy sword in her hands, she brought about a brief moment of peace and final prosperity to Britain.
A man in historical fact, but it seems that in this world she was a cross-dressing beauty.
One of the ideal kings that approves a virtuous life, a virtuous livelihood for the people.
A character with no faults that aided the weak and broke the strong.
Calm, cool and collected; an honor student who is always serious.
...that being said, although rarely mentioned, there is something of a sore loser in her: she does not go easy on any kind of competition and gets greatly vexed upon losing.
A natural talent to command an army corps.
In group battles, the abilities of one's own army are raised.
Honest and upright, a king that sticked to with selfless devotion.
The knights fell on their knees before such righteousness and the people found the hope to bear poverty.
Her royal principles was not for the sake of a handful of warriors, but to govern the many, powerless people.
Rank: A++ Type: Anti-Fortress
Not a man-made weapon, but a Divine Construct forged by the planet. A Noble Phantasm that stand at the top of all holy swords.
It is not the sword, but its scabbard that truly possesses an outstanding ability. However, that scabbard has been forever lost.
The conclusion of Arthurian Legends marks the end of the age of knights.
Although King Arthur managed to repel the aliens*, she was not able to avoid the ruin of the land of Britain itself.
The rebellion of Mordred - one of the Knights of the Round Table - caused the country to be split into two, and the castle of knights, Camelot, lost its light.
At Camlann Hill, King Arthur defeated Mordred, but also sustained a wound herself and fell on her knees.
Just before drawing her last breath, she gave custody of the holy sword to her last loyal retainer, Bedivere, and departed from this world.
It has been said that, after death, she was carried to Avalon - the utopia, paradise that does not exists anywhere in this world - and will save Britain again in the far away future.
The theme played during her Noble Phantasm is "Excalibur" from Fate/hollow ataraxia.
In the North American release of Fate/Grand Order her name was changed to Altria Pendragon instead of retaining the long accepted Artoria Pendragon. This has lead to controversy within the fanbase between those preferring the original name, Artoria Pendragon, and those who prefer the official name given by the North American release. Technically neither are actually wrong though for the sake of seniority, and the past Fate works that use the name Artoria, the name Artoria is utilized as "Official" by the fanbase despite technically Altria being "Official" as well based off the North American release of Fate/Grand Order. Nonetheless this has lead to confusion among newer and less experienced Fate fans who only know her by her North American Fate/Grand Order name of Altria Pendragon.
