In a parallel universe where Admiral James Leyton succeeded in his coup d'état against the Federation Council, the Federation is sent into a devastating civil war. Jonathan Masters leaves Starfleet after the loss of the USS Swiftfire (NCC-76125) and joins the Maquis in their struggle to protect their homes from the rampaging Klingon Empire. However, he has little interest in the fate of the Maquis or the Demilitarized Zone. He only has one goal: to gain bloody vengeance on those who have caused him pain: the Klingons.
- This episode was originally written as part of an anthology set in the Star Trek: Pendragon universe. Later it was moved out of that universe into a new one that was inspired by Pendragon. The story was taken offline in 2013 to undergo these changes.
- The reboot of the series in 2016 has thrown up questions as to if this particular story will be continued due to possible changes in the new continuity. However, prime timeline counterparts of characters from this story will appear in Star Trek: The Farthest Star.
- The title comes from lyrics from the song, "Lost" by VAST.
- While the story is set in an alternate universe the point of divergence is the Star Trek: Deep Space Nine episode "Paradise Lost" where Admiral Leyton's coup against the Federation Council was successful instead of failing.
