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!
This trade paperback collects the 5-issue series into one volume, with a
