Alviss sat down on the floor and for the first time his face lost its look of anger. "It was long ago," he said. "More years than you mortals can reckon. But I was an adventurous lad and one night I crossed the bridge Bifrost from Midgard to Asgard. Asgard, you understand, is the land of the old gods, but I was safe there as long as it was dark. While I was there, I met Thrud, only daughter of Thor, god of the yeomen and peasants, dispenser of thunder. Aye, she was beautiful--more beautiful than you'd know, Kevan MacGreene--and I knew she was the lass for Alviss. It seemed that she felt the same way about me, despite the fact that she was three times my height. Hand in hand, we went to see Thor--faith and there's one for whom I would set bear traps every night if he were my father-in-law." "I gather that he turned you down?" Kevan said. "Worse," said Alviss. Rage and sorrow intermingled on his face. "By the beard of Daoine Glas, he tricked me. He said that Thrud could marry me and come away if I would answer thirteen questions. Bad cess to him, I agreed. His twelve questions were to give the names for the world, the moon, the sun, the clouds, the wind, the calm, the sea, the trees, the night, fire, wheat and beer in all the worlds of the Aesir, Vanir, giants, elves and gods." "What are they?" Kevan asked curiously. "There is no time to tell you, as you will see. But I was then fresh from visiting the worlds he'd mentioned and I knew the names well. We sat there in Thor's palace, Belskirnir, before a great roaring fire--Thor holding his great head in his hands as he listened, Thrud sitting beside me and holding my hand--and I recited the names. It was a long task and I didn't notice that it was daylight as I finished. I spoke the last name and then demanded Thrud's hand. Thor only grinned and pointed. I turned to look in the direction he was pointing and the last thing I saw in Asgard was the sun streaming through the window. As it touched me, I turned to stone." Two tears streaked down the dwarf's face and were lost in his red beard. "Why did you turn to stone?" Kevan asked. "It was the law of the land--and still is," said Alviss. "If the sun shines on any of the Little People while in Asgard, they turn to stone. Thor had tricked me. I would be there still if Hreidmar and Sindri hadn't come to rescue me. As soon as they carried me back to Midgard, the spell was gone and I was myself again. But Thrud was lost to me forever." "Why didn't you go back some night and get her?" asked Kevan. Being a practical man, he added, "Or why didn't she run away and join you?" "You're excessively stupid, even for a mortal," snapped the dwarf. "Once the spell had been upon me, I would turn to stone should I ever again set foot in Asgard. And it has been decreed that there are only three ways in which Thrud may ever leave Asgard. Hand in hand with her true love, carried over Bifrost by a mortal, or when she goes to Gimli after Ragnarok."
