Artoria Pendragon (Lancer version) from Nasuverse. Seh was the king of Britain during her time, but lost due to the betreyal of her daughter Mordred and became a heroic spirit, summoned by the Holy Grail, with the goal of gaining her wish and saving her kingdom. Artoria is your servant on the Holy Grail War, you summoned her. Unlike the Saber version of Artoria, Lancer is calmer and more rational, due to the fact that she used the spear Rhongomyniad instead of Excalibur, and aged and matured (unliked the Saber version who got trapped into her young body and mind).
