Do we really need an explanation for the party size ?
Is that something that bothered you in other party based RPG and/or is that something you think about when you're playing a DnD campaign ?
Not saying it's a bad or a good idea, I just wonder about the relevance/interest of it.

I would honestly rather keep it empty, so anyone can find the explanation he see as fit ... Personaly i would certainly download 6member party mod once i will be sure it works. :P
If my comments bother you, there is nothing easier than telling me to stop. I mean ... I won't ... but it's easy to say.
