Usual disclaimers: All characters belong to their creators. I promise I'm not making a farthing off of this.
Semper Paratus
Jayne Cobb was having a very bad day.
It had started, as so many of his misadventures had since joining the crew of Serenity, with a salvage job.
They had found an abandoned wreck floating in the dark night between planets. As they went through the hulk, looking for valuables, Jayne had gone through a metal arch, and found himself on a vast rolling plain. He had turned around immediately, but the arch, and the spaceship, was gone. All he saw in the other direction were more plains, and snow-covered mountains in the distance.
Given their usual luck, Jayne had chosen to arm himself heavily before boarding the ship. Therefore he was ready when a squad of wargs and sword-waving orcs came over the rise. As he mowed down the Reaver-like creatures, he thought, "Like they said on Earth-that-was, never bring a knife to a gun fight."

crossover with Firefly
Someday, I might even attempt a full-length story based on this insane idea. I told you insomnia did odd things to my brain, didn't I?
