Typical indeed of the male inhabitants of Opar was the lone watcher upon the outer city wall, a short, stocky man with matted hair and beard, his tangled locks growing low upon a low, receding forehead; small, close-set eyes and fang-like teeth bore evidence of his simian ancestry, as did his short, crooked legs and long, muscular ape-like arms, all scantily hair-covered as was his torso. As his wicked, blood-rimmed eyes watched the progress of the party across the valley toward Opar, evidences of his growing excitement were manifested in the increased rapidity of his breathing, and low, almost inaudible growls that issued from his throat. The strangers were too far distant to be recognizable only as human beings, and their number to be roughly approximated as between two and three score. Having assured himself of these two facts the watcher descended from the outer wall, crossed the space between it and the inner wall, through which he passed, and at a rapid trot crossed the broad avenue beyond and disappeared within the crumbling but still magnificent temple beyond. Cadj, the High Priest of Opar, squatted beneath the shade of the giant trees which now overgrew what had once been one of the gardens of the ancient temple. With him were a dozen members of the lesser priesthood, the intimate cronies of the High Priest, who were startled by the sudden advent of one of the inferior members of the clan of Opar. The fellow hurried breathlessly to Cadj. “Cadj,” he cried, “strange men descend upon Opar! From the northwest they have come into the valley from beyond the barrier cliffs—fifty of them at least, perhaps half again that number. I saw them as I watched from the summit of the outer wall, but further than they are men I cannot say, for they are still a great distance away. Not since the great Tarmangani came among us last have there been strangers within Opar.” “It has been many moons since the great Tarmangani who called himself Tarzan of the Apes was among us,” said Cadj. “He promised us to return before the rain to see that no harm had befallen La, but he did not come back and La has always insisted that he is dead. Have you told any other of what you have seen?” he demanded, turning suddenly upon the messenger. “No,” replied the latter. “Good!” exclaimed Cadj. “Come, we will all go to the outer wall and see who it is who dares enter forbidden Opar, and let no one breathe a word of what Blagh has told us until I give permission.” “The word of Cadj is law until La speaks,” murmured one of the priests. Cadj turned a scowling face upon the speaker. “I am High Priest of Opar,” he growled. “Who dares disobey me?” “But La is High Priestess,” said one, “and the High Priestess is the queen of Opar.” “But the High Priest can offer whom he will as sacrifice in the Chamber of the Dead or to the Flaming God,” Cadj reminded the other meaningly. “We shall keep silence, Cadj,” replied the priest, cringing.
