This has me curious, I just read the Alien Spotlight story, a couple of days ago. I wasn't sure if it was a story that goes into late 2265 or sometime in 2266. I haven't read the Byrne story yet, but does something specfically place it in 2266?
It's a direct prequel to "Balance of Terror," showing how and why the Commander was sent on the mission depicted in that episode. Therefore it must take place very soon before BoT, only as much time as it takes to travel from Romulus to the Neutral Zone.
And I'm confused. The Alien Spotlight
Romulan story is
the Byrne story. So how can you have just read it and not read it yet?
