Black Amazon of Mars

Grimly Eric John Stark slogged toward that ancient Martian city—with every step he cursed the talisman of Ban Cruach that flamed in his blood-stained belt. Behind him screamed the hordes of Ciaran, hungering for that magic jewel—ahead lay the dread abode of the Ice Creatures—at his side stalked the whispering spectre of Ban Cruach, urging him on to a battle Stark knew he must lose!
Through all the long cold hours of the Norland night the Martian had not moved nor spoken. At dusk of the day before Eric John Stark had brought him into the ruined tower and laid him down, wrapped in blankets, on the snow. He had built a fire of dead brush, and since then the two men had waited, alone in the vast wasteland that girdles the polar cap of Mars.
Now, just before dawn, Camar the Martian spoke.
Stark.
Yes?
I am dying.
Yes.
I will not reach Kushat.
No.
Camar nodded. He was silent again.
The wind howled down from the northern ice, and the broken walls rose up against it, brooding, gigantic, roofless now but so huge and sprawling that they seemed less like walls than cliffs of ebon stone. Stark would not have gone near them but for Camar. They were wrong, somehow, with a taint of forgotten evil still about them.
The big Earthman glanced at Camar, and his face was sad. A man likes to die in his own place, he said abruptly. I am sorry.
