Re: Help me select a ship
It isn't clear to me which era your story would be taking place in. TOS? TMP? Post-TMP? Pre-TNG? TNG? DS9/VOY? Post-VOY?
It's easiest in most of these eras to suggestion a Constellation-class vessel, which would seem to be a new design in roughly the TMP era. If your story were set in TOS/TAS or TMP, you might want to look at a Miranda variant (one without the torpedo "roll bar").
It was never clear to me what era the Centaur-class vessels
came from, maybe post-TMP. Depending on the era of your story, one of these might be ideal.
The stories begin 10 years after Nemesis.
The meaning of the apocalypse is the opposite of what most people think. It does not mean the end of the world; it means the revealing of hidden secrets and the beginning of a heaven on earth. The apocalypse is starting now.
