Mars's vast Olympus Mons naval base, where Alex sees youthful military confidence masking a system that may be quietly failing.
Hecate Base is a major Martian Navy installation tunneled into Olympus Mons, with broad corridors, base housing, checkpoints, bars, administrative centers, and a culture shaped by deployments and military aspiration. It is where Alex Kamal trained and served, and he returns to find that people know him as the Rocinante's famous pilot.
Behind the familiar rituals, the base holds a dangerous secret. Commander Winston Duarte acknowledges that the Navy may no longer know where its assets are, and the programmer Duarte names as a source is found dead in base housing before Alex can speak to him.
A vast buried Martian military complex of wide corridors, transit walkways, security checkpoints, base housing, service ads, and severe Navy administrative spaces inside Olympus Mons.
Hecate is the institutional heart of Mars's Navy and a place where its declining control becomes visible.
