Fate/Zero

Saber is surprised by the sudden arrival of Waver and Rider at Castle Einzbern. Rider declares his intention to have a peaceful discussion with her and Archer on the subject of kingship and the wishes they want the Grail to grant. Archer wants it merely so that people can't "steal" it from him, while Rider wants it to be reincarnated and get his dream of world conquest. Saber argues that a king should serve his people selflessly and wishes to use the Grail's power to save Britain. Rider criticizes her, saying that Saber's emotional distance from her subjects led to their dissatisfaction and proposes his own ideal, namely that people should serve the king, whose extravagant ambitions inspire them in turn. Their talk is interrupted by the arrival of the Assassins. When they rebuff Rider's offer to join the feast, Rider summons his Noble Phantasm called Ionian Hetairoi, composed of the vast number of loyal soldiers who also became Servants after their deaths. Rider and his army easily decimate every single Assassin. With their meeting over, Rider tells Saber that he no longer recognizes her as a king and departs. A conflicted Saber reveals to Irisviel that one of her knights (Tristan) left Camelot because he was dissatisfied with her rule.
