Re: The Children of Kings
Or, in the Abramsverse had an earlier Enterprise that wasn't a Constitution class. Was it ever refereed to as Constitution class or by NCC-1701? Either way, it's not Prime Universe.
With the exception of 'Black Snow', I saw nothing that precluded this from taking place in the Prime universe. Even then I thought the author attempted to make it wash with 'Balance of Terror'.
