Here’s another revision of the crawl that I rather like. This one will probably be what I go with.
Episode VII
THE FORCE AWAKENSLuke Skywalker has vanished. In his absence, the sinister FIRST ORDER has risen in secret from the ashes of the fallen Empire.
Failing to convince the New Republic to combat this emerging threat, General Leia Organa mobilizes a covert RESISTANCE to gather allies from the farthest reaches of the galaxy.
Desperate for her brother’s help, Leia has sent her most trusted pilot on a daring mission to Jakku, where a clue has been discovered to Luke’s whereabouts…
This is good! I also like “fallen”, but if you wanted to use a word closer to fractured, you could also say, “from the ashes of the shattered Empire.”
