Hel-light from Hela's halls!" And at her word, a most peculiar light pervaded the cave, and there was that about its luminance that actually affrighted. Again she spoke:
"Michael Commnenus, you utterly vile worm of the earth! You know that your doom is upon you—but as yet you know not why. O beast lower than the swine! Harken and remember my words even after eternity is swallowed up in the Twilight of the Gods! You are a modern, and know not that the self, the soul, is eternal, undying, changing its body and name in every clime and period, yet ever the same soul, responsible for the deeds of its bodies. You have even prated of your soul—when in fact, you are the property of the soul!
"Watch, now!" She pointed to the cave entrance. "Behold there the wisps of sea-fog gathering; and gradually will come the rising tide. And on the curtain of that cold, swirling mist, behold the pictures of the past—a past centuries old; a past wherein your craven, treacherous soul sinned beyond all pardon!
"Look you, too, Jarl Wulf Red-Brand, so that in all the days remaining to you upon Earth, you may know that his doom was just, and that Heldra is but executing a merited penalty!
"And while the shuttles of the Norns weave the tapestry of the sin of this Commnenus, I will tell all the tale of his crimes.
"In Byzantium reigned the emperor, Alexander Commnenus. Secure his throne, guarded by the ponderous axes and the long swords of the Varangians, the splendid sons of the Norse-lands, who had gone a-viking. Trusted and loved were the Varangs by the emperor, and oft he boasted of their fidelity, swearing on the cross of Constantine that to the last man would his Varangs perish ere one would flinch a step from overwhelming foes, citing in proof their battle-cry:
"'Valhalla! Valhalla! Victory or Valhalla!'
"Into the harbor of the Golden Horn sailed the viking long-ship, the Grettir. Three noble brothers owned her—Thorfinn, Arvid, Sven. With them sailed their sister . . . her fame as an Alruna-maid, prophetess and priestess, was sung throughout the Norse-lands. No man so low but bore her reverence. Sin it was to cast eyes of desire on any Alruna, and the sister of the three brothers was held especially holy.
"Between the hands of the Emperor Alexander Commnenus, the three brethren placed their hands, swearing fealty for a year and a day. Thirty fighting-men, their crew, followed wherever the three brothers led. And the great emperor, hearing of their war-fame from others of the Varangian guard, gave the brothers high place in his esteem, and held them nigh his own person.
"Their sister, the Alruna-maid, was treated as became her rank and holy repute. Aye! Even in Christian Byzantium respect and honor were shown her by the priests of an alien belief. But one man in Byzantium aspired more greatly than any other, Norseman or Byzantine, had ever dared.
"A Commnenus he, grand admiral of Byzantium's war fleet, nephew to the emperor, enjoying to the full the confidence and love of his imperial uncle. Notorious for his profligacy, he cast his libertine eyes on the Norse Alruna-maid, but with no thought of making her his wife. Nay! 'Twas only as his leman he desired her. . . . So, he plotted. . . .
"The three brothers, Thorfinn, Arvid, Sven, with their full crew, in the longship Grettir were ordered to sea to cruise against certain pirates harrying a portion of the emperor's coasts.
