外来的挑战(14)
The cone-shaped terrestrial beings kept the one existing cube in a special shrine as a relique and basis for experiments, till after aeons it was lost amidst the chaos of war and the destruction of the great polar city where it was guarded. When, fifty million years ago, the beings sent their minds ahead into the infinite future to avoid a nameless peril of inner earth, the whereabouts of the sinister cube from space were unknown.
This much, according to the learned occultist, the Eltdown Shards had said. What now made the account so obscurely frightful to Campbell was the minute accuracy with which the alien cube had been described. Every detail tallied—dimensions, consistency, hieroglyphed central disc, hypnotic effects. As he thought the matter over and over amidst the darkness of his strange situation, he began to wonder whether his whole experience with the crystal cube—indeed, its very existence—were not a nightmare brought on by some freakish subconscious memory of this old bit of extravagant, charlatanic reading. If so, though, the nightmare must still be in force; since his present apparently bodiless state had nothing of normality in it.
