I’m still thinking about my ‘Sith Fleet as the MacGuffin’ idea, so I came up with a crawl:

The iron grip of the FIRST ORDER has spread to the farthest reaches of the galaxy. Whispers of a long abandoned IMPERIAL FLEET circulate the core worlds.
GENERAL LEIA ORGANA dispatches secret agents to gather intelligence while SUPREME LEADER KYLO REN, determined to crush the RESISTANCE, searches the galaxy for this rumored fleet.
Meanwhile REY, the last hope of the Jedi, researches ancient Jedi texts hoping to find clues to defeat her dreaded rival…

I feel like it’s missing something, and I feel like the last sentence can be improved. Keep in mind, with this version, the opening would pan down to the Resistance base where Rey is levitating.
