"She half expected, despite her brave words, to come out upon the storied and familiar red-hot pave of hell, and this pleasant, starlit land surprised her and made her wary. The things that built the tunnel could not have been human. She had no right to expect men here. She was a little stunned by finding open sky so far underground, though she was intelligent enough to realize that however she had come, she was not underground now. No cavity in the earth could contain this starry sky."

“Now she took the sword back into her hand and knelt on the rim of the invisible blackness below. She had gone this path once before and once only, and never thought to find any necessity in life strong enough to drive her down again. The way was the strangest she had ever known. There was, she thought, no such passage in all the world save here. It had not been built for human feet to travel. It had not been built for feet at all. It was a narrow, polished shaft that cork-screwed round and round. A snake might have slipped in it and gone shooting down, round and round in dizzy circles—but no snake on earth was big enough to fill that shaft. No human travelers had worn the sides of the spiral so smooth, and she did not care to speculate on what creatures had polished it so, through what ages of passage.”

“Beauty is as tangible as blood, in a way. It is a separate, distinct force that inhabits the bodies of men and women. You must have noticed the vacuity that accompanies perfect beauty in so many women...the force so strong that it drives out all other forces and lives vampirishly at the expense of intelligence and goodness and conscience and all else.”

“It was a long way down. Before she had gone very far the curious dizziness she had known before came over her again, a dizziness not entirely induced by the spirals she whirled around, but a deeper, atomic unsteadiness as if not only she but also the substances around her were shifting. There was something queer about the angles of those curves. She was no scholar in geometry or aught else, but she felt intuitively that the bend and slant of the way she went were somehow outside any other angles or bends she had ever known. They led into the unknown and the dark, but it seemed to her obscurely that they led into deeper darkness and mystery than the merely physical, as if, though she could not put it clearly even into thoughts, the peculiar and exact lines of the tunnel had been carefully angled to lead through poly-dimensional space as well as through the underground—perhaps through time, too.”

“Nothing I have ever written was given the slightest deliberation. It was there in the typewriter and it came out, a total bypassing of the brain.”

“All about her, as suddenly as the awakening from a dream, the nothingness had opened out into undreamed-of distances. She stood high on a hilltop under a sky spangled with strange stars. Below she caught glimpses of misty plains and valleys with mountain peaks rising far away. And at her feet a ravening circle of small, slavering, blind things leaped with clashing teeth.”

“And not until then did she remember how fatal it is said to be to accept a gift from a demon. Buy, or earn it, but never accept the gift.”
