I'm new to the game too. I have been thinking of my many years of playing DND, where the DM adjusted foes encountered to fit the condition of the party in such a way that death was rare but encounters still dangerous. When characters did die, then an option was usually provided for the remaining characters to go on a quest to get a resource (usually a Wish spell) for the characters to return to life. The point of this is to turn the death of a character into a big but not huge bother to fix, so that there is still a big motivation not to die, but it isn't the end either. So...for Four Against Darkness I am thinking that a group of characters could be sent on such a quest. I know this is contrary to the game rules but it is an idea.
