Terra has suffered a rupture in its history and technological progress. No one knows the stories of the people of the past, nor of the heroes and glories of ages gone by. They seem to have been forgotten in some corner of history.
Only when the Heroic Spirits revived did everyone seem to learn of Terra's glorious past!
Did the Knight King, wielding the holy sword, once lead Kazimierz, establish the first Round Table of Knights, and wage war across the land?
Did the Saint, a peasant girl who stepped forward in a time of crisis, lead Gaul to glory?
Did Ivan the Terrible rule Ursus through absolute might and hegemony?
And what of the heroes and demigods from the Age of the Gods? Did they all leave behind their own glorious legacies?
At this moment, everyone on Terra understood one thing: their ancestors had all been rich and powerful!
Chen: "So you're a Heroic Spirit too?"
Emiya: "I'm not, I haven't. I'm just an ordinary, nameless hero."
