Esau Cairn, having defeated the ape-like man, "despoiled him" of his loincloth and dagger and fled into the hills away from additional man-like figures approaching in the distance. He is soon confronted with the dilemma of drinking eating and staying alive in an alien wilderness, occupied by predominantly feline predators. Wounded by one great beast he finds himself fleeing from a pack of small arboreal felines, up a tree and onto a niche I a cliff:

"Evidently their climbing ability did not include cliffs...Neither did they abandon their post. Stars came out, strange unfamiliar constellations, that blazed whitely I the dark velvet skies, and a broad golden moon rose above the cliffs, and flooded the hills with weird light; but still my sentinels sat on the branches below me and howled up at me their hatred and belly hunger...I can understand why our heathen ancestors worshipped the sun."

Esau Cairn is alone on a savage planet, teeming with beasts that are hungry for his flesh.
