A/N: Ringing in the new year by posting a oneshot for Rogue One. I loved the movie, but this is, well, how it should have ended. I do not own Star Wars nor Star Trek.

Beam 'Em Up, Scotty!

Captain James T. Kirk of the U.S.S. Enterprise, NCC-1701, was not having a good day. First, he was in the middle of a nice cup of coffee when the Enterprise was pulled into some kind of singularity and spit out… somewhere. That somewhere, at least, was a tropical planet of some kind.

But then things went south when that somewhere turned a war zone as they were hailed by some officer representing something called the First Galactic Empire. Said Empire, upon calling their ship "Rebel scum", had immediately opened fire. The Enterprise's shields were holding for now, though.

And then the giant moon appeared out of nowhere. Even Spock was having a hard time wrapping his head around what was obviously a giant weapon.

"Mr. Sulu…" Kirk said, trying to regain his bearings. "How many people are down there?"

"Thousands, sir," Sulu answered.

"Captain," Spock interjected. "We cannot interfere with this conflict. It is quite clear that this Empire is trying to quash a rebellion of some kind."

"You saw that moon!" Chekov shouted from his seat before Kirk could answer. "That's not quashing a rebellion, that's overkill!"

"Captain," Uhura chimed in from her place at the comm station, "a large transmission is being beamed up to one of the ships in the rebel fleet."

"Try to intercept," Kirk ordered.

"Working on it…" Uhura murmured, only to shout a few seconds later, "I got something… it looks to be… plans of some kind."

Kirk looked out the viewport, to the battle raging around them and the moon-sized weapon beyond. "I think I know."

Spock seemed to pick up on this. "Plans to the weapon…"

It was then that the moon fired, a pulse of bright green light racing down to strike the planet below.

"Mr. Sulu-"

"On it. We can't beam all those people up at once, the transporters can't handle that."

"Find a few, then."

"Got 'em. Two lifeforms, headed towards a beach. The shockwave will reach them in two minutes, ten seconds."

Plenty of time. Kirk radioed down to Engineering. "Scotty, we got two lifeforms down there about to get pulverized. Beam 'em up."

"Aye, Captain! Give me a few seconds… got 'em! Ha ha!"

"Mr. Spock, Uhura, with me," Kirk ordered. "Mr. Sulu, you have the conn. Get us out of here."

"Aye, Captain."

"Captain," Scotty's voice came over the comm, "Our guests look a lit beat up; I'm sending 'em off to Sickbay."

"Acknowledged, Scotty."

Jyn Erso awoke to a bright light in her eyes.

"Agh!" she moaned. "Wh-where am I?"

"Easy there, miss," an unfamiliar voice said. "You're safe. I'm Leonard Mccoy, but call me 'Bones'. And you are..?"

Jyn wasn't sure about all of this, but what harm could it do? "Jyn."

"Lovely name. Well, Jyn, welcome to the USS Enterprise."

"The… Enterprise?"

"The captain'll explain later to you and your companion. For now, rest; you two look like you've been through hell."

"Cassian? Where is he?"

"He's out like a light on your right."

Jyn looked over, and sure enough, Cassian lay just a few feet away, asleep, alive.

A few days later, Jyn and Cassian returned to Yavin IV, beating the Death Star by a matter of hours. The Enterprise, with all its weaponry and technology, proved crucial to the success of the Rebels in the ensuing battle.
