No room in the temple for a couple of refugees then?
Could have even pulled an SF staple and stuck them on prehistoric earth, making them the Preservers.
I mean, Kira was literally inside the Wormhole, but that didn't protect her from being nullified from history once the First Splinter Timeline branching event was retroactively prevented. The Prophets had no capacity to save them -- but they DID promise to do the very thing people in the last few posts were complaining no one did: remember and honor the First Splinter's heroes.
And once again, Coda is about how we respond to the inescapable fact that we are going to die and cannot escape this fact. Do we respond by embracing nihilism or existentialism? Coda is clearly on the side of existentialism and depicts the embodiment of nihilism (the Devidians) as evil and a threat to all life. Giving the characters a way to escape death would have undermined the thematic integrity of the story.
The reality is that Coda is in someways a fitting end for the litverse, as it fits well with some of its more less than hopeful bits.
I think Coda is very hopeful. It insists that death cannot prevent us from imbuing our lives with meaning.
