Legend Theory

I have a theory. All the legends (excluding Aran) inherit something.

Aran: He's the original legend so...
Evan: Inherits the dragon/method of fighting with a dragon.
Dual Blade (Yes, I know it isn't confirmed but, due to some of the videos and my theory, he could be the legend.): Inherits the method of fighting with two blades, due to Syl finding scrolls or something showing how to fight like that. (This part isn't my theory, it is someone else's, but I don't know his/her name.)
Bowman Legend: Inherits this: http://www.southperry.net/showthread.php?t=37082, although, that one is a flawed theory.
Pirate Legend: Inherits a gun/knuckler (depending on if he's a gunslinger or brawler) that can level up as you advance. Or it's the mechanic and inherits fighting with a robot or the robot he fights with.

So, what do you think?

It IS confirmed. The Dual Blade is confirmed not to be a legend.

The only thing Aran and Evan have in common is that they communicate with their weapons: Mir the Dragon and Maha the Polearm.

Then the theif inherits some method of fighting or something.

Those are the only things we KNOW of.
