LMAO! I should word that better, huh. I do not know how to word it. It's fine I suppose in that kind of world. Fate Stay is great!! But I was hoping to take inspiration from writing our own lore.

I would go with that personally. Inventing "Ancient heroes that changed the world through card magic only to be forgotten" feels more in keeping with the genre. Like how the none of the egyptian god cards in Yogioh were actual gods from mythology.
