Off the top of my head, trek lit also narrated the genesis wave disaster,
I never read those books; they certainly never had much in the way of emotional consequences in other books. I seem to remember that the gender of Nurse Ogawa's kid was different in them vs in the
Titan series, and that the last book in that series (
Genesis Force) featured, in essence, a
Star Trek version of the X-Men.
the Cold equations 3 destruction,
Haven't read that one yet. I'm only halfway through Book II. No spoilers, please.
the millenium trilogy war end federation defeat,
Oh, we're counting alternate timelines that get erased from history?
Okay.
Well, there was that time the Federation was losing a war to the Klingons in an alternate timeline. (TNG: "Yesterday's
Enterprise")
And that time the Federation was erased from history. (
Star Trek: First Contact)
And that time that the entire galaxy was consumed by an anti-time anomaly billions of years ago. (TNG: "All Good Things...")
And that time Earth was destroyed by the Xindi in the year 2153. (ENT: "Twilight")
And that time the Federation was erased from history by the survival of Edith Keeler in the 1930s. (TOS: "The City on the Edge of Forever")
And that time the Federation was forced to abandon Deep Space 9 to the Klingons after a Dominion-subverted Klingon government came to dominate the Alpha Quadrant of the 2400s. (DSN: "The Visitor")
And that time the entire Sol system was vaporized in the 29th Century by the ineptitude of 20th Century entrepreneur Henry Starling. (VOY: "Future's End")
And that time the eastern United States was conquered by Nazi Germany in the 1940s. (ENT: "Storm Front")
Even books not geared toward large body counts depict loss of iconic symbols - DS9,
You mean like the destruction of the original starship
Enterprise? (
Star Trek III: The Search for Spock)
Or the destruction of the starship
Enterprise the audience had spent the most time with, the
Enterprise-D? (
Star Trek: Generations)
Or the destruction of the much-loved
U.S.S. Defiant? (DSN: "The Changing Face of Evil")
most of the voyager fleet.
Is the rest of that fleet really "iconic?"
And since we're talking about alternate timelines, we should probably mention the sheer number of times
Voyager has been blown up.
