Aside from cosmetic differences is there a real difference? From what I've heard the sword of might is really Excalibur and together they can be an all-powerful weapon capable of reshaping the cosmic.

But on their own what is the difference? As far as I can tell they grant the exact same abilities. The only thing I can tell is one is the path of violence, but why is that such a choice?

And why was Lionheart unable to see her children for choosing the sword and why did Brian not tell her?

thanks
