Marentina is an isolated yellow Martian city on the Red Planet’s North Pole that is ruled by the wise and just Jeddak of the North, Talu, who is in rebellion against his tyrannical uncle, Salenus Ull, Jeddak of Jeddaks of Okar.
“Nestled in a deep valley lay a city of Martian concrete, whose every street and plaza and open space was roofed with glass. All about lay snow and ice, but there was none upon the rounded, domelike, crystal covering that enveloped the whole city. Then I saw how these people combated the rigors of the arctic, and lived in luxury and comfort in the midst of a land of perpetual ice. Their cities were veritable hothouses, and when I had come within this one my respect and admiration for the scientific and engineering skill of this buried nation was unbounded. . .
