Warlord of Mars: Fall of Barsoom Vol. 1: Collection

100,000 years before the time of John Carter! Barsoom is a dying world: its once mighty oceans are receding and its atmosphere grows more tenuous by the day. The Orovars, who have dominated for a million years, are on the verge of extinction at the hands of the Green Hordes and the emerging Red Martians. Two Orovars - a Scientist and a General - race against time to save their people before Mars plunges into barbarism!
