EPISODE VII
THE FORCE AWAKENS

It is a time of darkness.
Luke Skywalker, striving
to reforge the legendary
Jedi Order, has vanished.

Emboldened by the Jedi’s
absence, warriors of the
evil FIRST ORDER have
risen from the shadows
of an Imperial fortress to
conquer isolated worlds
beyond the reach of the
fledgling New Republic.

Desperate to unite these
planets in RESISTANCE,
a fearless militia loyal to
the New Republic has
sent its most daring pilot
to find the last Jedi and
restore the light of hope
to the darkening stars….
