I was browsing apocalyptic plot devices at [link=http://tvtropes.org]TVTropes[/link], when a thought hit me: how would those sort of stories work in SW? Of course they can't have an actual "end of the world" plot, but how could it work? What kinds of apocalypses (apocalypsi?) could work? Zombies? A virus? Droid takeover? Ewoks escaping the confines of Endor and unleashed upon an unsuspecting Galaxy?
