The Diamond Throne

Prologue
    Ghwerig and the Bhelliom – From the Legends of the Troll-Gods
    At the dawn of time, long before the ancestors of Styricum slouched, fur-clad and club-wielding, out of the mountains and forests of Zemoch onto the plains of central Eosia, there dwelt in a deep cavern lying beneath the perpetual snows of northern Thalesia a dwarfed and misshapen Troll named Ghwerig. Now, Ghwerig was an outcast by reason of his ugliness and his overwhelming greed, and he laboured alone in the depths of the earth, seeking gold and precious gems that he might add to the treasure-hoard which he jealously guarded. Finally there came a day when he broke into a deep gallery far beneath the frozen surface of the earth and beheld by the light of his flickering torch a deep blue gemstone, larger than his fist, embedded in the wall. Trembling with excitement in all his gnarled and twisted limbs, he squatted on the floor of that passage and gazed with longing at the huge jewel, knowing that its value exceeded that of the entire hoard which he had laboured for centuries to acquire. Then he began with great care to cut away the surrounding stone, chip by chip, so that he might lift the precious gem from the spot where it had rested since the world began. And as more and more it emerged from the rock, he perceived that it had a peculiar shape, and an idea came to him. Could he but remove it intact, he might by carefulcarving and polishing enhance that shape and thus increase the value of the gem a thousand-fold.
    When at last he gently took the jewel from its rocky bed, he carried it straightaway to the cave wherein lay his workshop and his treasure-hoard. Indifferently, he shattered a diamond of incalculable worth and fashioned from its fragments tools with which he might carve and shape the gem which he had found.
    For decades, by the light of smoky torches, Ghwerig patiently carved and polished, muttering all the while the spells and incantations which would infuse this priceless gem with all the power for good or ill of the Troll-Gods. When at last the carving was done, the gem was in the shape of a rose of deepest sapphire blue. And he named it Bhelliom, the flower-gem, and he believed that by its might all things might be possible for him.
    But though Bhelliom was filled with all the power of the Troll-Gods, it would not yield up that power unto its misshapen and ugly owner, and Ghwerig pounded his fists in rage upon the stone floor of his cavern. He consulted with his Gods and made offerings to them of heavy gold and bright silver, and his Gods revealed to him that there must be a key to unlock the power of Bhelliom, lest its might be unleashed by the whim of any who came upon it. Then the Troll-Gods told Ghwerig what he must do to gain mastery over the gem which he had wrought. Taking the shards which had fallen unnoticed in the dust about his feet as he had laboured to shape the sapphire rose, he fashioned a pair of rings. Of finest gold were the rings, and each was mounted with a polished oval fragment of Bhelliom itself. When it was done, he placed the rings one on each of his hands and then lifted the sapphire rose. The deep, glowing blue of the stones mounted in his rings fled back into Bhelliom itself, and the jewels that adorned his twisted handswere now as pale as diamond. And as he held the flower-gem, he felt the surge of its power, and he rejoiced in the knowledge that the jewel he had wrought had consented to yield to him.
    As the uncounted centuries rolled by, great were the wonders Ghwerig wrought by the power of Bhelliom. But the Styrics came at last into the land of the Trolls. When the Elder Gods of Styricum learned of Bhelliom, each in his heart coveted it by reason of its power. But Ghwerig was cunning and he sealed up the entrances to his cavern with enchantments to repel their efforts to wrest Bhelliom from him.
    Now at a certain time, the Younger Gods of Styricum took counsel with each other, for they were disquieted about the power which Bhelliom would confer upon whichever God came to possess it, and they concluded that such might should not be unloosed in the earth. They resolved then to render the stone powerless. Of their number they selected the nimble Goddess Aphrael for the task. Then Aphrael journeyed to the north, and, by reason of her slight form, she was able to wriggle her way through a crevice so small that Ghwerig had neglected to seal it. Once she was within the cavern, Aphrael lifted her voice
