I wrote one fic, and received three, all of them interesting and unique:
The Fixed Point (2108 words), Star Trek: The Next Generation
Rating: General Audiences
Relationships: Ian Andrew Troi I/Lwaxana Troi
Summary: Cadet Ian Troi meets the woman he's going to marry.
Grave Accents (1540 words), Star Wars Original Trilogy, Star Wars Prequel Trilogy
Characters: Mace Windu, Leia Organa, Anakin Skywalker
Summary: In retrospect, Mace decided, it had mostly been Qui-Gon’s fault. He was measured enough not to blame the master for the entire state of affairs; after all, it was not Qui-Gon but chance or the will of the Force that had brought young Leia to Jedha.
One Is a Whole Number (1148 words), Star Wars - All Media Types
Characters: Rey (Star Wars), Ahsoka Tano
Summary: Being in an isolated spot in the whole wide galaxy still means you're part of it.
Thoughts: I had a lot of fun writing for it, and I got some great fics, and there are a lot of other great fics. However, 1k words is really short for a time-travel story. It's barely enough to even set up what happens, much less explore the ramifications. There are so many fics I wish were longer.
