WIP Big Bang poll (and commentary)

I'm going to do WIP Big Bang this year. I've done a quick narrowing down of fics I'd like to finish. Since I write in a wide variety of fandoms, I'm going to do a quick pitch for each of them regardless of fandom.

ETA: I've added "Scions of the Tomb" to the list, but unfortunately I can't put it in the poll. The blurb/teaser is in the comments.
