Director J.J. Abrams hasn't shot a single roll of film, and 'Star Wars: Episode 7' has already sparked more rumors than we can count. But this one might actually be something worth paying attention to.

According to sources at Schmoes Know, Abrams has sent out a casting breakdown that, if accurate, reveals the basic gist of the movie's storyline, as well as what looks like its two main characters. This is obviously nothing you want to read if you're trying to stay spoiler-free before 'Star Wars: Episode 7' arrives in theaters in 2015, but if you just can't help yourself, here goes. Ready?

Storyline: Two 17-year-old twins, a girl and a boy, are trained by their uncle Luke to be the greatest Jedi’s in the galaxy. Problems arise when the male twin turns to the dark side.

Jaina Solo – Female, 17 years old, lead. – Jacen’s twin sister, one of the greatest Jedi’s in the galaxy, trained by her uncle Luke Skywalker.

Jacen Solo – Male, 17 years old, lead – Jaina’s twin brother, one of the greatest Jedi’s in the world. A loner who is constantly struggling with the idea of what’s right and what’s wrong. Starts to turn to the dark side. Full of conviction that what he is doing is the “right thing." Will eventually become Darth Caedus.

This isn't the first time we've heard that 'Star Wars: Episode 7' would focus on the Solo kids, and it also jibes with the return of original stars Mark Hamill, Harrison Ford and Carrie Fisher. As the Schmoes report points out, these characters should be familiar to anyone who's spent time with the 'Star Wars' Expanded Universe, and seeing their names here -- as well as their lightsaber-wielding uncle's -- should be a source of comfort to fans who've worried about the EU's place in the franchise now that Disney is running the show.

On the other hand, it's probably worth taking this report with a giant grain of salt (or glitterstim spice) -- the 'Star Wars' galaxy has been thick with rumors ever since Disney announced that new movies were in the works, and we surely haven't seen the last of them. Still, it's intriguing to consider the possibilities, and the Jacen/Jaina storyline is one worthy of building a new trilogy around (albeit one whose contours will be familiar to anyone who watched the originals). At the very least, it'll be interesting to see where this leads.
