I'm not expecting you to write long pieces; just write as often and as much as you want, and I'll move the story forward as needed, using new posts or adding to yours as needed. The point for you is making a few key decisions (i.e. go for the bridge or enginarium, help Xerza or shoot her in the head, that sort of thing), theer rest is just my attempt at A) adding background and integrating NPCs into the campaing and B) helping you get into the 40k mood (as presented by me - there are a million different 40k verses out there, but this one is mine).

And yes, you can gain xtra XP, items, contacts etc. Not a whole lot, but a little. Likewise you CAN die, but only if you're really really stupid (see, you don't die until your Fate Points are gone - but you don't want to start the campaign having spent all of them during the plelude ;-)
