Valles Marineris

Valles Marineris appears in Red Rising Saga.

Valles Marineris emerges as a pivotal Martian landmark that transforms from a mere geographical reference in the early books to a critical strategic theater in the later saga. Initially absent from the narrative, this vast canyon system becomes central to the escalating conflict between the rising Republic and the Society remnants. By Dark Age, it serves as both a physical battleground and a symbolic representation of Mars itself—ancient, unyielding, and ultimately the stage for humanity's most desperate struggles for control of the Red Planet.
