>>40103859Nothing warmer than nuclear hellfire, right?
Spoiler explanation ahead, I really recommend just giving it a read
Not really, though;
nuclear desruction of Ohio, Earth is more used as a plot piece to add meat to the MC and do some world-building for the new world he'll find himself in, as well as transition into that world itself.
It's kinda overdramatic toward the end of the whole nuclear destruction thing but is otherwise done surprisingly well, especially in the follow through of what the story does with it after-the-fact.
