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, plotting a return to Imperial rule.
Failing to convince the New Republic to combat this emerging threat, General Leia Organa gathers allies from the farthest reaches of the galaxy to form a covert RESISTANCE.
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…
You’re overthinking things now for sure. I like this second paragraph, but the first is too much. “Plotting its return to power” is perfect I think because, with the comma, it seems to imply that the First Order is plotting the Empire’s return to power.
