Insight
Adventurer
I'm pretty keen to develop a group history and build to that rather than a specific concept (though I may be barking up the wrong tree here, what with all the concepts already submitted) and since Insight has given us the green light to do some world-building I think we should run with it.
I mean, we have the time and all. A week.
Any group would need to encompass all the possible PCs.
-------
Idea the 1st: PCs are the founders of a border town nearish where the adventures start. This would allow the inclusion of all the submissions as 'NPCs' and alternates.
-------
Idea the 2nd: PCs all got together initially at the reading of a Will. The Will stipulated that they do tasks A, B, C, etc. Around task H or so, they'd discovered that they sorta had something good going and kept it up after the Will was properly executed.
-------
Idea the 3rd: Sort of an obvious one, the PCs are agents of a King or Council and do work chiefly for the Crown (or Council). They are all identified by a signature cloak they wear (when on official business) that gives their band it's name, The Red/Skull/Mist/Star/Stone/Dark Cloaks.

Not the 2nd idea, please. It's too close to something you'll be doing later. I like taking the initiative, though!
