I would like to read about the final mission/loss of the Enterprise B. Haynes' Enterprise Guide touched on an end but I'd like an account told. If the B was MIA, it'd be cool to see a story where her wreckage is found.
I would also like to see a tale of the ring-ship Enterprise told as a primitive space travel story (and could be a great first contact tale).
I love hostory so tales that concrete the legacy of the Enterprise would be great.
Lastly, I want to see the return of the Voth.
