Warily the two Tecuhltli led Conan along the hall beyond the bronze door, and through chamber after chamber shimmering in the green fire. They saw no one, heard no sound. After they crossed the Great Hall which bisected the city from north to south, their caution was increased by the realization of their nearness to enemy territory. But chambers and halls lay empty to their wary gaze, and they came at last along a broad dim hallway and halted before a bronze door similar to the Eagle Door of Tecuhltli. Gingerly they tried it, and it opened at silently under their fingers. Awed, they started into the green-lit chambers beyond. For fifty years no Tecuhltli had entered those halls save as a prisoner going to a hideous doom. To go to Xotalanc had been the ultimate horror that could befall a man of the western castle. The terror of it had stalked through their dreams since earliest childhood. To Yanath and Topol that bronze door was like the portal of hell.
They cringed back, unreasoning horror in their eyes, and Conan pushed past them and strode into Xotalanc.
Timidly they followed him. As each man set foot over the threshold he stared and glared wildly about him. But only their quick, hurried breathing disturbed the silence.
They had come into a square guardroom, like that behind the Eagle Door of Tecuhltli, and, similarly, a hall ran away from it to a broad chamber that was a counterpart of Olmec's throne room.
Conan glanced down the hall with its rugs and divans and hangings, and stood listening intently. He heard no noise, and the rooms had an empty feel. He did not believe there were any Xotalancas left alive in Xuchotl.
"Come on," he muttered, and started down the hall.
He had not gone far when he was aware that only Yanath was following him. He wheeled back to see Topal standing in an attitude of horror, one arm out as if to fend off some threatening peril, his distended eyes fixed with hypnotic intensity on something protruding from behind a divan.
"What the devil?" Then Conan saw what Topal was staring at, and he felt a faint twitching of the skin between his giant shoulders. A monstrous head protruded from behind the divan, a reptilian head, broad as the head of a crocodile, with down-curving fangs that projected over the lower jaw. But there was an unnatural limpness about the thing, and the hideous eyes were glazed.
Conan peered behind the couch. It was a great serpent which lay there limp in death, but such a serpent as he had never seen in his wanderings. The reek and chill of the deep black earth were about it, and its color was an indeterminable hue which changed with each new angle from which he surveyed it. A great wound in the neck showed what had caused its death.
"It is the Crawler!" whispered Yanath.
"It's the thing I slashed on the stair," grunted Conan. "After it trailed us to the Eagle Door, it dragged itself here to die. How could the Xotalancas control such a brute?"
The Tecuhltli shivered and shook their heads.
"They brought it up from the black tunnels below the catacombs. They discovered secrets unknown to Tecuhltli."
"Well, it's dead, and if they'd had any more of them, they'd have brought them along when they came to Tecuhltli. Come on."
They crowded close at his heels as he strode down the hall and thrust on the silver-worked door at the other end.
"If we don't find anybody on this floor," he said, "we'll descend into the lower floors. We'll explore Xotalanc from the roof to the catacombs. If Xotalanc is like Tecuhltli, all the rooms and halls in this tier will be lighted—what the devil!"
They had come into the broad throne chamber, so similar to that one in Tecuhltli. There were the same jade dais and ivory seat, the same divans, rugs and hangings on the walls. No black, red-scarred column stood behind the throne-dais, but evidences of the grim feud were not lacking.
Ranged along the wall behind the dais were rows of glass-covered shelves. And on those shelves hundreds of human heads, perfectly preserved, stared at the startled watchers with emotionless eyes, as they had stared for only the gods knew how many months and years.
Topal muttered a curse, but Yanath stood silent, the mad light growing in his wide eyes. Conan frowned, knowing that Tlazitlan sanity was hung on a hair-trigger.
Suddenly Yanath pointed to the ghastly relics with a twitching finger.
"There is my brother's head!" he murmured. "And there is my father's younger brother! And there beyond them is my sister's eldest son!"
Suddenly he began to weep, dry-eyed, with harsh, loud sobs that shook his frame. He did not take his eyes from the heads. His sobs grew shriller, changed to frightful, high-pitched laughter, and that in turn became an unbearable screaming. Yanath was stark mad.
Conan laid a hand on his shoulder, and as if the touch had released all the frenzy in his soul, Yanath screamed and whirled, striking at the Cimmerian with his sword. Conan parried the blow, and Topal tried to catch Yanath's arm. But the madman avoided him and with froth flying from his lips, he drove his sword deep into Topal's body. Topal sank down with a groan, and Yanath whirled for an instant like a crazy dervish; then he ran at the shelves and began hacking at the glass with his sword, screeching blasphemously.
Conan sprang at him from behind, trying to catch him unaware and disarm him, but the madman wheeled and lunged at him, screaming like a lost soul. Realizing that the warrior was hopelessly insane, the Cimmerian side-stepped, and as the maniac went past, he swung a cut that severed the shoulder-bone and breast, and dropped the man dead beside his dying victim.
Conan bent over Topal, seeing that the man was at his last gasp. It was useless to seek to stanch the blood gushing from the horrible wound.
"You're done for, Topal," grunted Conan. "Any word you want to send to your people?"
"Bend closer," gasped Topal, and Conan complied—and an instant later caught the man's wrist as Topal struck at his breast with a dagger.
"Crom!" swore Conan. "Are you mad, too?"
"Olmec ordered it!" gasped the dying man. "I know not why. As we lifted the wounded upon the couches he whispered to me, bidding me to slay you as we returned to Tecuhltli—" And with the name of his clan on his lips, Topal died.
Conan scowled down at him in puzzlement. This whole affair had an aspect of lunacy. Was Olmec mad, too? Were all the Tecuhltli madder than he had realized? With a shrug of his shoulders he strode down the hall and out of the bronze door, leaving the dead Tecuhltli lying before the staring dead eyes of their kinsmen's heads.
Conan needed no guide back through the labryinth they had traversed. His primitive instinct of direction led him unerringly along the route they had come. He traversed it as warily as he had before, his sword in his hand, and his eyes fiercely searching each shadowed nook and corner; for it was his former allies he feared now, not the ghosts of the slain Xotalancas.
He had crossed the Great Hall and entered the chambers beyond when he heard something moving ahead of him—something which gasped and panted, and moved with a strange, floundering, scrambling noise. A moment later Conan saw a man crawling over the flaming floor toward him—a man whose progress left a broad bloody smear on the smoldering surface. It was Techotl and his eyes were already glazing; from a deep gash in his breast blood gushed steadily between the fingers of his clutching hand. With the other he clawed and hitched himself along.
"Conan," he cried chokingly, "Conan! Olmec has taken the yellow-haired woman!"
"So that's why he told Topal to kill me!" murmured Conan, dropping to his knee beside the man, who his experienced eye told him was dying. "Olmec isn't as mad as I thought."
Techotl's groping fingers plucked at Conan's arm. In the cold, loveless, and altogether hideous life of the Tecuhltli, his admiration and affection for the invaders from the outer world formed a warm, human oasis, constituted a tie that connected him with a more natural humanity that was totally lacking
