Pitviper

Pitvipers debut in Red Rising as mutated, cold-blooded tunnel serpents infesting the Martian mines, their black oil-like bodies and thigh-thick forms making them lethal ambush predators. These stubborn creatures burrow into warm suits to lay eggs, with their venomous bites leaving twin scars and their young proving especially poisonous to the lowReds. Across the series they remain emblematic of the brutal subterranean dangers that shape the underclass, evolving from background environmental hazards into recurring symbols of the oppressive world Darrow seeks to upend.
