it tapped into my primal sci-fi mind.
There was a title of a Star Trek episode – the name was so wonderful to my ears:
The city at the edge of forever
it was a nod to Doctor Who, but done in a Star Trek way.
The title is just wonderful though. strong combinations of words are not easy to find — you could just easily say “frontier” — but to say it’s at the “edge of the known world”, well that flair is irresistible.
