Insiders

Deep within Kerberos Station, pipe crawler Sachi Inside is dying of the planet-killing Hibravian virus. In a state of delirium, the agoraphobic girl agrees that in exchange for life, she will not only leave her pipes, but even the station. A sentient plant wraps around her, guides her to an exiting ship, and adheres to the hull.
Captain Karasi Kwei is not pleased to discover a stowaway, but the crew thinks there's money to be made on the plant, and the fact that both the Eastern Star Corporation and the Elysium Empire are tracking it confirms its value. However, none of that matters when the entire crew falls sick with the incurable Hibravian.
But Sachi's plant is more than it seems. All they have to do is fight the mercenaries, survive the virus, evade the Elysium Empire, and navigate a fluctuating microwave wall, and they just might save the universe.
