"Or any three or four clans," admitted the slayer. "But some day a man will rise and unite thirty or forty clans, just as was done among the Cimmerians, when the Gundermen tried to push the border northward, years ago. They tried to colonize the southern marches of Cimmeria: destroyed a few small clans, built a fort-town, Venarium — you've heard the tale."

"So I have indeed," replied Balthus, wincing. The memory of that red disaster was a black blot in the chronicles of a proud and warlike people. "My uncle was at Venarium when the Cimmerians swarmed over the walls. He was one of the few who escaped that slaughter. I've heard him tell the tale, many a time. The barbarians swept out of the hills in a ravening horde, without warning, and stormed Venarium with such fury none could stand before them. Men, women, and children were butchered. Venarium was reduced to a mass of charred ruins, as it is to this day. The Aquilonians were driven back across the marches, and have never since tried to colonize the Cimmerian country. But you speak of Venarium familiarly. Perhaps you were there?"

"I was," grunted the other. "I was one of the horde that swarmed over the walls. I hadn't yet seen fifteen snows, but already my name was repeated about the council fires."

Balthus involuntarily recoiled, staring. It seemed incredible that the man walking tranquilly at his side should have been one of those screeching, blood-mad devils that poured over the walls of Venarium on that long-gone day to make her streets run crimson.

"Then you, too, are a barbarian!" he exclaimed involuntarily.

The other nodded, without taking offense.

"I am Conan, a Cimmerian."

"I've heard of you." Fresh interest quickened Balthus' gaze. No wonder the Pict had fallen victim to his own sort of subtlety! The Cimmerians were barbarians as ferocious as the Picts, and much more intelligent. Evidently Conan had spent much time among civilized men, though that contact had obviously not softened him, nor weakened any of his primitive instincts. Balthus' apprehension turned to admiration as he marked the easy catlike stride, the effortless silence with which the Cimmerian moved along the trail. The oiled links of his armor did not clink, and Balthus knew Conan could glide through the deepest thicket or most tangled copse as noiselessly as any naked Pict that ever lived.

"You're not a Gunderman?" It was more assertion than question.

Balthus shook his head. "I'm from the Tauran."

"I've seen good woodsmen from the Tauran. But the Bossonians have sheltered you Aquilonians from the outer wilderness for too many centuries. You need hardening."

That was true; the Bossonian marches, with their fortiied villages filled with determined bowmen, had long served Aquilonia as a buffer against the outlying barbarians. Now among the settlers beyond Thunder River here was growing up a breed of forest men capable of meeting the barbarians at their own game, but their numbers were still scanty. Most of the frontiersmen were like Balthus — more of the settler than the woodsman type.

The sun had not set, but it was no longer in sight, hidden as it was behind the dense forest wall. The shadows were lengthening, deepening back in the woods as the companions strode on down the trail.

"It will be dark before we reach the fort," commented Conan casually; then: "Listen!"

He stopped short, half crouching, sword ready, transformed into a savage figure of suspicion and menace, poised to spring and rend. Balthus had heard it too — a wild scream that broke at its highest note. It was the cry of a man in dire fear or agony.

Conan was off in an instant, racing down the trail, each stride widening the distance between him and his straining companion. Balthus puffed a curse. Among the settlements of the Tauran he was accounted a good runner, but Conan was leaving him behind with maddening ease. Then Balthus forgot his exasperation as his ears were outraged by the most frightful cry he had ever heard. It was not human, this one; it was a demoniacal caterwauling of hideous triumph that seemed to exult over fallen humanity and find echo in black gulfs beyond human ken.

Balthus faltered in his stride, and clammy sweat beaded his flesh. But Conan did not hesitate; he darted around a bend in the trail and disappeared, and Balthus, panicky at finding himself alone with that awful scream still shuddering through the forest in grisly echoes, put on an extra burst of speed and plunged after him.

The Aquilonian slid to a stumbling halt, almost colliding with the Cimmerian who stood in the trail over a crumpled body. But Conan was not looking at the corpse which lay there in the crimson-soaked dust. He was glaring into the deep woods on either side of the trail.

Balthus muttered a horrified oath. It was the body of a man which lay there in the trail, a short, fat man, clad in the gilt-worked boots and (despite the heat) the ermine-trimmed tunic of a wealthy merchant. His fat, pale face was set in a stare of frozen horror; his thick throat had been slashed from ear to ear as if by a razor-sharp blade. The short sword still in its scabbard seemed to indicate that he had been struck down without a chance to fight for his life.

"A Pict?" Balthus whispered, as he turned to peer into the deepening shadows of the forest.

Conan shook his head and straightened to scowl down at the dead man.

"A forest devil. This is the fifth, by Crom!"

"What do you mean?"

"Did you ever hear of a Pictish wizard called Zogar Sag?"

Balthus shook his head uneasily.

"He dwells in Gwawela, the nearest village across the river. Three months ago he hid beside this road and stole a string of pack-mules from a pack-train bound for the fort — drugged their drivers, somehow. The mules belonged to this man" — Conan casually indicated the corpse with his foot — "Tiberias, a merchant of Velitrium. They were loaded with ale-kegs, and old Zogar stopped to guzzle before he got across the river. A woodsman named Soractus trailed him, and led Valannus and three soldiers to where he lay dead drunk in a thicket. At the importunities of Tiberias, Valannus threw Zogar Sag into a cell, which is the worst insult you can give a Pict. He managed to kill his guard and escape, and sent back word that he meant to kill Tiberias and the five men who captured him in a way that would make Aquilonians shudder for centuries to come.

"Well, Soractus and the soldiers are dead. Soractus was killed on the river, the soldiers in the very shadow of the fort. And now Tiberias is dead. No Pict killed any of them. Each victim — except Tiberias, as you see — lacked his head — which no doubt is now ornamenting the altar of Zogar Sag's particular god."

"How do you know they weren't killed by the Picts?" demanded Balthus.

Conan pointed to the corpse of the merchant.

"You think that was done with a knife or a sword? Look closer and you'll see that only a talon could have made a gash like that. The flesh is ripped, not cut."

"Perhaps a panther — " began Balthus, without conviction.

Conan shook his head impatiently.

"A man from the Tauran couldn't mistake the mark of a panther's claws. No. It's a forest devil summoned by Zogar Sag to carry out his revenge. Tiberias was a fool to start for Velitrium alone, and so close to dusk. But each one of the victims seemed to be smitten with madness just before doom overtook him. Look here; the signs are plain enough. Tiberias came riding along the trail on his mule, maybe with a bundle of choice otter pelts behind his saddle to sell in Velitrium, and the thing sprang on him from behind that bush. See where the branches are crushed down.
