'Aye; a cosmic source was turned against him. But now that source is again in his hands, and he will see that it is not stolen again.'

'And what is this d.a.m.nable source?' demanded Conan irritably.

'It is called the Heart of Ahriman. When Acheron was overthrown, the primitive priest who had stolen it and turned it against Xaltotun hid it in a haunted cavern and built a small temple over the cavern. Thrice thereafter the temple was rebuilt, each time greater and more elaborately than before, but always on the site of the original shrine, though men forgot the reason therefore. Memory of the hidden symbol faded from the minds of common men, and was preserved only in priestly books and esoteric volumes. Whence it came no one knows. Some say it is the veritable heart of a G.o.d, others that it is a star that fell from the skies long ago. Until it was stolen, none had looked upon it for three thousand years.

'When the magic of the Mitran priests failed against the magic of Xaltotun's acolyte, Altaro, they remembered the ancient legend of the heart, and the high priest and an acolyte went down into the dark and terrible crypt below the temple into which no priest had descended for three thousand years. In the ancient iron-bound volumes which speak of the Heart in their cryptic symbolism, it is also told of a creature of darkness left by the ancient priest to guard it.

'Far down in a square chamber with arched doorways leading off into immeasurable blackness, the priest and his acolytes found a black stone altar that glowed dimly with inexplicable radiance.

'On that altar lay a curious gold vessel like a double-valved sea-sh.e.l.l which clung to the stone like a barnacle. But it gaped open and empty. The Heart of Ahriman was gone. While they stared in horror, the keeper of the crypt, the creature of darkness, came upon them and mangled the high priest so that he died. But the acolyte fought off the being - a mindless, soulless waif of the pits brought long ago to guard the Heart and escaped up the long black narrow stairs carrying the dying priest, who before he died, gasped out the news to his followers, bade them submit to a power they could not overcome, and commanded secrecy. But the word has been whispered about among the priests, and we of Asura learned of it.'

'And Xaltotun draws his power from this symbol',' asked Conan, still skeptical.

'No. His power is drawn from the black gulf. But the Heart of Ahriman came from some far universe of flaming light, and against it the powers of darkness cannot stand, when it is in the hands of an adept. It is like a sword that might smite at him, not a sword with which he can smite. It restores life, and can destroy life. He has stolen it, not to use against his enemies, but to keep them from using it against him.'

'A sh.e.l.l-shaped bowl of gold on a black altar in a deep cavern,' Conan muttered, frowning as he sought to capture the illusive image. 'That reminds me of something I have heard or seen. But what, in Crom's name, is this notable Heart?'

'It is in the form of a great jewel, like a ruby, but pulsing with blinding fire with which no ruby ever burned. It glows like living flame-'

But Conan sprang suddenly up and smote his right fist into his left palm like a thunderclap.

'Crom!' he roared, 'What a fool I've been! The Heart of Ahriman! The heart of my kingdom! Find the heart of my kingdom, Zelata said. By Ymir, it was the jewel I saw in the green smoke, the jewel which Tarascus stole from Xaltotun while he lay in the sleep of the black lotus!'

Hadrathus was also on his feet, his calm dropped from him like a garment.

'What are you saying? The Heart stolen from Xaltotun?'

'Aye!' Conan boomed. 'Tarascus feared Xaltotun and wanted to cripple his power, which he thought resided in the Heart.

Maybe he thought the wizard would die if the Heart was lost. By Crom - ahhh!' With a savage grimace of disappointment and disgust he dropped his clenched hand to his side.

'I forgot. Tarascus gave it to a thief to throw into the sea. By this time the fellow must be almost to Kordava. Before I can follow him he'll take ship and consign the Heart to the bottom of the ocean.'

'The sea will not hold it!' exclaimed Hadrathus, quivering with excitement. 'Xaltotun would himself have cast it into the ocean long ago, had he not known that the first storm would carry it ash.o.r.e. But on what unknown beach might it not land!'

'Well,' Conan was recovering some of his resilient confidence, 'there's no a.s.surance that the thief will throw it away. If I know thieves - and I should, for I was a thief in Zamora in my early youth - he won't throw it away. He'll sell it to some rich trader. By Crom!' he strode back and forth in his growing excitement. 'It's worth looking for! Zelata bade me find the heart of my kingdom, and all else she showed me proved to be truth. Can it be that the power to conquer Xaltotun lurks in that crimson bauble?'

'Aye! My head upon it!' cried Hadrathus, his face lightened with fervor, his eyes blazing, his fists clenched. 'With it in our hands we can dare the powers of Xaltotun! I swear it! If we can recover it, we have an even chance of recovering your crown and driving the invaders from our portals. It is not the swords of Nemedia that Aquilonia fears, but the black arts of Xaltotun.,

Conan looked at him for a s.p.a.ce, impressed by the priest's fire.

'It's like a quest in a nightmare,' he said at last. 'Yet your words echo the thought of Zelata, and all else she said was truth. I'll seek for this jewel.'

'It holds the destiny of Aquilonia,' said Hadrathus with conviction. 'I will send men with you-'

'Nay!' exclaimed the king impatiently, not caring to be hampered by priests on his quest, however skilled in esoteric arts. 'This is a task for a fighting man. I go alone. First to Poitain, where I'll leave Albiona with Trocero. Then to Kordava, and to the sea beyond, if necessary. It may be that, even if the thief

intends carrying out Tarascus' order, he'll have some difficulty finding an outbound ship at this time of the year.'

'And if you find the Heart,' cried Hadrathus, 'I will prepare the way for your conquest. Before you return to Aquilonia I will spread the word through secret channels that you live and are returning with a magic stronger than Xaltotun's. I will have men ready to rise on your return. They will rise, if they have a.s.surance that they will be protected from the black arts of Xaltotun.

'And I will aid you on your journey.'

He rose and struck a gong.

'A secret tunnel leads from beneath this temple to a place outside the city wall. You shall go to Poitain on a pilgrim's boat. None will dare molest you.'

'As you will.' With a definite purpose in mind Conan was afire with impatience and dynamic energy. 'Only let it be done swiftly.'

In the meantime events were moving not slowly elsewhere in the city. A breathless messenger had burst into the palace where Valerius was amusing himself with his dancing-girls, and throwing himself on his knee, gasped out a garbled story of a b.l.o.o.d.y prison break and the escape of a lovely captive. He bore also the news that Count Thespius, to whom the execution of Albiona's sentence had been entrusted, was dying and begging for a word with Valerius before he pa.s.sed.

Hurriedly cloaking himself, Valerius accompanied the man through various winding ways, and came to a chamber where Thespius lay. There was no doubt that the count was dying; b.l.o.o.d.y froth bubbled from his lips at each shuddering gasp. His severed arm had been bound to stop the flow of blood, but even without that, the gash in his side was mortal.

Alone in the chamber with the dying man, Valerius swore softly.

'By Mitra, I had believed that only one man ever lived who could strike such a blow.'

'Valerius!' gasped the dying man. 'He lives! Conan lives!'

'What are you saying?' e.j.a.c.u.l.a.t.ed the other.

'I swear by Mitra!' gurgled Thespius, gagging on the blood that gushed to his lips. 'It was he who carried off Albiona! He is not dead - no phantom come back from h.e.l.l to haunt us. He is flesh and blood, and more terrible than ever. The alley behind the tower is full of dead men. Beware, Valerius - he has come back - to slay us all-'

A strong shudder shook the blood-smeared figure, and Count Thespius went limp.

Valerius frowned down at the dead man, cast a swift glance about the empty chamber, and stepping swiftly to the door, cast it open suddenly. The messenger and a group of Nemedian guardsmen stood several paces down the corridor. Valerius muttered something that might have indicated satisfaction.

'Have all the gates been closed?' he demanded.

'Yes, your Majesty.'

'Triple the guards at each. Let no one enter or leave the city without strictest investigation. Set men scouring the streets and searching the quarters. A very valuable prisoner has escaped, with the aid of an Aquilonian rebel. Did any of you recognize the man?'

'No, your Majesty. The old watchman had a glimpse of him, but could only say that he was a giant, clad in the black garb of the executioner, whose naked body we found in an empty cell.'

'He is a dangerous man,' said Valerius. 'Take no chances with him. You all know the Countess Albiona. Search for her, and if you find her, kill her and her companion instantly. Do not try to take them alive.'

Returning to his palace chamber, Valerius summoned before him four men of curious and alien aspect. They were tall, gaunt, of yellowish skin, and immobile countenances. They were very similar in appearance, clad alike in long black robes beneath which their sandaled feet were just visible. Their features were shadowed by their hoods. They stood before Valerius with their hands in their wide sleeves; their arms folded. Valerius looked at them without pleasure. In his far journeyings he had encountered many strange races.

'When I found you starving in the Khitan jungles,' he said abruptly, 'exiles from your kingdom, you swore to serve me.

You have served me well enough, in your abominable way. One more service I require, and then I set you free of your oath.

'Conan the Cimmerian, king of Aquilonia, still lives, in spite of Xaltotun's sorcery - or perhaps because of it. I know not. The dark mind of that resurrected devil is too devious and subtle for a mortal man to fathom. But while Conan lives I am not safe. The people accepted me as the lesser of two evils, when they thought he was dead. Let him reappear and the throne will be rocking under my feet in revolution before I can lift my hand.

'Perhaps my allies mean to use him to replace me, if they decide I have served my purpose. I do not know. I do know that this planet is too small for two kings of Aquilonia. Seek the Cimmerian. Use your uncanny talents to ferret him out wherever he hides or runs. He has many friends in Tarantia. He had aid when he carried off Albiona. It took more than one man, even such a man as Conan, to wreak all that slaughter in the alley outside the tower. But no more. Take your staffs and strike his trail. Where that trail will lead you, I know not. But find him! And when you find him, slay him!'

The four Khitans bowed together, and still unspeaking, turned and padded noiselessly from the chamber.
