I don’t remember the story in general. But it would be cool to have a game that shows the first Exault. I remember thinking it was Marth. But if I’m not mistaken Grima attacked Archanea a thousand years ago. And Marth was even older. And that was when some changes happened until the Chrom and Lucina era.
Do you think you can explore more?
I have to go after curiosities and remember what happened in the game.
Although there is always a Master Sword in Fire Emblem with a change of time and generation. It seems that the most fun in the same game is still Judgral.
