I am not sure about making the Republic so directly dependent on a single Jedi for its survival, even Luke. It kind of infantilizes them to make it so all they need is a consultation with Luke. Keep in mind, even Snoke believes that the threat of Luke isn’t the man himself but the ‘new Jedi’ that he may inspire.

As for crisis, I put it back in the first paragraph because it was in the third. I think when we get to that third paragraph it’s nice to have a term to encapsulate everything that’s happened so far.

EPISODE VII
THE FORCE AWAKENS

The galaxy is in crisis.
Luke Skywalker, sworn
to rebuild the legendary
Jedi Order, has vanished.

With the Jedi now facing
extinction, agents 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.

Unable to end this crisis
without the mighty Jedi,
the Senate has secretly
authorized the mission
of a brave RESISTANCE
to find their lost hero and
restore the light of hope
to the darkening stars….
