After an epic odyssey spanning the galaxy, a disparate team of con artists, scientists, and Firewall agents have finally cornered their quarry. There will be no more chases around the solar system or to a distant exoplanet. No more undercover missions or political intrigue. Now, there is only victory or death. A TITAN has taken over a remote Bernal Sphere habitat in the outer system. It appears to be damaged or only partially operational, as there are gaps in the station's defenses, gaps large enough for the team to enter the habitat and attempt to stop it.The secrets that lay at the heart of the station may change the future of transhumanity, if the team survives long enough to report back to Firewall. Duality concludes NOW!
