We know from the framing story of The Good That Men Do that the Federation isn't about to go anywhere.
They're ignoring things from Indistinguishable from Magic
, so I don't see a big deal in ignoring things from an Enterprise book. But I didn't say fall, I said decline.
Besides Star Trek: The Fall
sounds far more dramatic than Star Trek: The Decline
It has been a while since I read IDM
, what are they ignoring?
