TMC back story doesn't give the sword a name.  Once the game itself begins, it starts out as the Picori Blade, and when it's reforged it's called the White Sword.  It's not called the Four Sword until after you infuse it with the power of the Wind Element.

Look, I'm not trying to discourage you; I'm just giving you what I know to be truth.

Okay fine. I give up you win. You may now deliver coup de grace I'm prone. I too are a D'n'D Freak.

I knew I heard gustaf somewhere but i wasnt sure who it was but yeah it is the king guy that sounds right. But in the very beginning remember it tells you a legend about a hero that locked away all the evil monsters. :)
