I like the crawls above - tried taking the best elements of all of them, but with respectful nods to the way JJ likes his stories to unfold:

The dead speak! The villainous COUNT DOOKU has returned, to herald the return of his dark master, EMPEROR PALPATINE. Dooku is killed by Admiral Pryde, but not before revealing a secret Sith technique to create a new galactic navy where each ship gets its own Death Star laser!

Luke Skywalker’s message of hope has reached the far corners of the galaxy, and the civilians of countless worlds are almost committed - they need just one more famous hero to come and get them before they rise up to join the resistance against the evil FIRST ORDER and also the new and bigger FINAL ORDER.

Meanwhile, Rey has read in the Jedi texts that her force bond with Kylo Ren is a FORCE DYAD, which is one of the reasons she’s very powerful. But could there be another, darker source of her power? Watch the movie to find out! Also Finn will be there.
