Far beneath the surface of a planet wrapped in a toxic atmosphere, competing political ideologies stare each other down over a heavily militarised line that cuts through the city on their border. Among the dark rail tunnels and mine shafts are an unfinished treaty up for negotiation; a fanatical terrorist group with questionable backers; and ordinary people caught in the middle. In this claustrophobic environment, those who desire peace must act quickly or these tunnels will collapse in the fires of war.       _____   This story is based on a role-playing map game I GM'd awhile ago. The four main characters are based on the four players from that map game, and the general sequence of events follows the game as well.   Cover art: inncect (formerly astrxphoria) from wattpad.com, where this story was first published.
