But how do your characters come back to earth? They've experienced perhaps great adventures, now there's a lull in the action as they come to terms with what they've just gone through. How do they handle that? I love The Lord of the Rings for many reasons but the portrayal of Frodo becoming more and more tired as the stress of what he has to do becomes more and more of a burden is realistically shown. On the assumption your characters are not super heroes who never get tired or out of sorts, how do your characters handle setbacks, tiredness, illness etc?
How do they pick themselves up from "earth" to get back to their "mission"? Who helps them and how? Plenty to think about there!
