THE SHADOW FROM THE LAND OF THE THREE SUNS
"I went nearer the stone temple, and a huge doorway loomed in front of me. Within that portal were swirling shadows that seemed to dart and leer and try to snatch me inside that awful darkness. I thought I saw three flaming eyes in the shifting void of a doorway, and I screamed with mortal fear. In that noisome depth, I knew, lurked utter destruction—a living hell even worse than death. I screamed again. The vision faded."
“So in the year of the Black Goat there came unto Nath a shadow that should not be on Earth, and that had no form known to the eyes of Earth. And it fed on the souls of men; they that it gnawed being lured and blinded with dreams till the horror and the endless night lay upon them. Nor did they see that which gnawed them; for the shadow took false shapes that men know or dream of, and only freedom seemed waiting in the Land of the Three Suns. But it was told by priests of the Old Book that he who could see the shadow’s true shape, and live after the seeing, might shun its doom and send it back to the starless gulf of its spawning. This none could do save through the Gem; wherefore did Ka-Nefer the High-Priest keep that gem sacred in the temple. And when it was lost with Phrenes, he who braved the horror and was never seen more, there was weeping in Nath. Yet did the Shadow depart sated at last, nor shall it hunger again till the cycles roll back to the year of the Black Goat.”
"Where I had, in the landscape itself, seen the twisted, half-sentient tree, there was here visible only a gnarled, terrible hand or talon with fingers or feelers shockingly distended and evidently groping toward something on the ground or in the spectator’s direction."
