And in my surge of nerdom I was going to toss another idea out there for a Harry Potter fandom.
Smuttly/slashy post wizard war.
I'd love to play Draco (PB Boyd Holbrook) three of four years after the last book. He' kind of lost it, left the wizarding world completely and is living in London. He ended on such a tragic, broken note that his mind has almost splintered and he's convinced himself that his entire life in the wizarding world was all made up. He's living in squats and just trying to deal with his fractured mind.
So someone from Hogwarts past (could be Harry, Cedric, another original character-I'm open to anything!) finds him in London or is sent to find him oooorrr...who knows? Maybe Harry is sent to find him. Like I said I'm still brainstorming.
But I DO know that angsty, dark, smutty goodness ensues.
