Lamplighter Below

The Wave nearly ended Tahama. No one knows why it happened. Someone has to find out.
A deep patrol Crawler rolls into the Pale. Small crew. Dangerous mission. Mars volunteers without explaining himself, not to the crew, not to anyone.
The old world is still down there, broken and buried and full of things that used to be people. That's expected. What isn't: something is organizing those things.
Not everyone comes home.
The mist doesn't care about bravery.
Lamplighters do.
