Don't panic: the quotation marks above stand for "Story about." The scribbed idea before it also started with "Story about..." and so I was trying to save myself the agony of having to write it twice, which I have now done anyway, lo all these long years later.
So the complete prompt reads:
Story about God's favorite who falls, but doesn't know it.
I think originally I wanted to do some kind of epic/badass tale of a fallen archangel who's gone rogue and is still inflicting Old Testament wrath (now that I type all that out, it sounds suspiciously like the Kevin Smith movie Dogma), but this gives me an idea for a short play that could be both funny and meaningful. Pointed, even.
Who else wants to attempt this one?
