Stumped...plotwise

So after helping my Penny with her plot, I've found I'm at a loss with mine.
Although I am using the Labyrinth for inspiration, I would really prefer to not just make a steampunk version of the same story. I want an interpretation.

But that is causing problems since I don't know where to start.

Maybe I should approach this how I would directing a play. Of course, one does not generally change the plot when doing this, but it could help me figure out the most important elements of the story and figure out how to work them together there.

Somehow I need to figure this out. And maybe that's how. After all, I can come up with all the outlandish plot ideas, but in the end its gotta go back to the basics.

So to the excerptlopedia!
