This story takes place in 2268 (CE) in the third year of the U.S.S. Enterprise mission, after the starship’s response to a distress call from a colony on Beta XII-A (“Day of the Dove”).
And in 2292 after the collapse of the Klingon Empire and the Romulan Star Empire alliance, and just prior to the explosion of the Klingon moon, Praxis (Star Trek VI: The Undiscovered Country).
And in 2024.
All because of a missing woman.
