Another take on this ‘border territory’ idea:
EPISODE VII
THE FORCE AWAKENS
It is a time of darkness.
Luke Skywalker, striving
to restore the legendary
Jedi Order, has vanished.
With the shadow of evil
rising across the worlds
of the New Republic, a
few desperate Senators
have secretly called upon
a daring RESISTANCE to
search for the last Jedi
within the domain of the
vengeful fallen Empire.
Answering this call, the
ace pilot Poe Dameron
has discovered a clue to
Luke’s location on the
desolate world of Jakku,
unaware that the sinister
FIRST ORDER now rules
these darkening stars…
This feels pretty natural, except for the final lines where it implies that nobody knows about the First Order at all, which isn’t true.
Alternately:
EPISODE VII
THE FORCE AWAKENS
It is a time of darkness.
Luke Skywalker, striving
to restore the legendary
Jedi Order, has vanished.
With the New Republic
overwhelmed by turmoil,
a few desperate Senators
have secretly called upon
a brave RESISTANCE to
search for the last Jedi
within the domain of the
evil FIRST ORDER, heir
to the fallen Empire.
Answering this call, the
ace pilot Poe Dameron
has discovered a clue to
Luke’s location on the
desolate world of Jakku,
unaware of the shadow
now rising to extinguish
the darkening stars…
This one puts a lot of information in the second paragraph, but the upshot is that the First Order is established before the final lines and those can be put to use in hinting at Starkiller Base as well as setting up the first shot.
