Warlord of Mars Omnibus #2

In "Worms of Mars: Part One," John and his allies work to bring peace to a fractured region of Barsoom, even as the First Born resist the death of Issus. When Tars captures noble women of the First Born, John refuses to hold them hostage, earning the trust of Linea—whose warning reveals a terrifying threat: the high priest of Issus is preparing to activate a machine that could drain Barsoom’s atmosphere and kill all life on the planet. With Carthoris and Linea, John races to stop the ritual before it’s too late.

In "Worms of Mars: Part Two," John, Carthoris, and Linea descend into the depths of the Sea of Omean, racing against time to reach a hidden chamber housing a machine capable of unleashing catastrophic destruction across Barsoom. As they confront the device and shut it down, they face a deadly worm guardian that fatally wounds Linea. With her final breath, she calls upon the Black Pirates to end their war and forge peace with the red people of the surface.

In "Part One: The Shadow of the Temple," John races to save Dejah and Thuvia after discovering Matai Shang and Thurid’s secret plan to free them from the Temple of the Sun ahead of schedule. Pursuing them through treacherous terrain and evading capture at every turn, he finally tracks them to Shang’s mountain stronghold—only to lose them once more. With a new tracking device in hand and the last airship departing, John sets off on a desperate flight to reclaim his wife and the others before it’s too late.

In "Part Two: A Hero in Kaol," John crash-lands in the jungle realm of Kaol during his pursuit of Matai Shang’s airship. After rescuing a group of red men from a Tark ambush—only to discover their leader is Thuvia’s father—the two form an uneasy alliance to rescue their captives. With the help of the Jeddik of Kaol, who repairs John’s flier, they set out northward, but their flight over an icy mountain is abruptly interrupted when an unknown force takes control of the craft, sending them crashing into the wilderness.
