Saber (セイバー, Seibā?) is a Saber-class Servant able to be summoned by the Protagonist in the Grand Orders of Fate/Grand Order.



Saber's True Name is Fergus mac Róich (フェルグス・マック・ロイ, Ferugusu makku Roi?), a brave warrior from the Celtic mythology's Ulster Cycle.[1] A man who established a corner of the Knights of the Red Branch. A member of the Knights of the Red Branch, a magic sword-user that is also known as the friend and foster father of the hero Cú Chulainn.[1][2] He took Cú Chulainn from his mother Deichtine to serve as a soldier for Ulster.[3] His wife is a goddess of the forest, a Divine Spirit.[1]

He was the king of Ulster until being tricked out of his throne by Conchobar mac Nessa.[2] Later after Cú Chulainn returned from the land of shadows, Conchobar had Fergus's sons killed "out of lust for young women", causing Fergus to leave the knight order and defected to Ulster's enemy Connacht.[1][3] At the outbreak of the greatest war in Ulster legends, he stayed beside his lover Medb, queen of Connacht, and displayed his valour.[1]

Spurring on queen Medb of Connacht out of hatred for Conchobar, they went to war with Ulster, where he managed to corner Conchobar during the decisive battle.[2][3] He was kept from revealing his true prowess due the fact Cu Chulainn was in Ulster, but still reached the point where he was one step away from slaying King Conchobar.[1] Fergus was prevented from killing Conchobar, and was said to have redirected his rage over it upon three hills, using Caladbolg to blast the tops cleanly off them.[2]

Due to the Geis exchanged with Cú Chulainn at this occasion, he will achieve victory almost unconditionally in case there is a rematch with him. At the time of the second invasion of Ulster, Queen Medb was scheming her revenge against Cú Chulainn and she concluded that "Fergus existence will become a bother" and did not invite him to the battlefield. Afterwards, he was assassinated by a jealousy-driven King Ailill, Medb's husband. Even now, Fergus' reputation as a magnificent brave warrior has been left for posterity.[1]



He is known for his great generosity, who didn't felt envy nor fear.[1]

His wish for the Holy Grail is to "once again "get along" together with my wife and Medb". In other words, he wants a three-way with the two of them.[1]

Other appearancesEdit

Fergus is mentioned in Lancer's flashback in Fate/hollow ataraxia.[3]


Fergus was said to be the pride of the Red Branch Knights.[3] He wielded the sword Caladbolg, said to be Cú Chulainn's natural enemy.[2]

A great glutton that possessed matchless vigor and libido. There are not that many humans who can compare to his peerlessness.[1]
