Star Trek: Breaking Down The Discovery Season 3 Trailer
8. The Burn
We're familiar with David Ajala's new character, Cleveland “Book” Booker, from the previously released NYCC teaser trailer, but he gives us a little backstory for the world here.
Book tells Michael about "The Burn", which he describes as “the day the galaxy took a hard left and the Federation mostly collapsed." With numerous shots in this trailer showing the wreckage of what are likely Federation starships and starbases, as well as familiar alien species living amongst each other in a post-apocalyptic wasteland, it's clear some kind of catastrophe has befallen the United Federation of Planets.
But, keep in mind Book's description of the Federation of the 32nd century is that it is "mostly" collapsed and we see later in the trailer that there are remnants of the organization we once knew as well as a slick, redesigned UFP flag.
