I hope I'm cool enough to be here, [and do we just post short stories? or are there plots we right about?]
In the forum at large, anything goes. This thread specifically deals in short stories related to the prompts posted each week; the stories can be one-shots if you like, self-contained chapters that build on the same characters and universes if you want. We've had authors write about events in class storylines, in faction/galactic lines, and in completely made-up plots set before, during, or after the canon storyline events.
