This week, somewhere in the third quarter of your story, something completely unexpected happens. Your characters must not see this coming, and preferably your reader won't either. Note this isn't the ending - you still have the final quarter in which to show us how your characters deal with whatever the buggery bollocks it was that just happened.

If you want a flashrule I will tell you what the unexpected event is. But, I don't want you to know what it is until you get to the point in your story at which the unexpected event occurs. Accordingly, flashrules will not be handed out until after sign-ups have closed.

If you want a hellrule I will give you a lego set from which you will derive your characters and setting.
