EPISODE VII
THE FORCE AWAKENS

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

Emboldened by the Jedi’s
absence, soldiers of the
evil FIRST ORDER have
risen from the shadows
of an Imperial fortress
to claim supremacy over
all star systems beyond
the fragile New Republic.

Desperate to unite these
planets in RESISTANCE,
a militia armed in secret
by the New Republic has
sent its pilots in search of
the last Jedi, seeking to
restore the light of hope
to the darkening stars….
