His name means all-wise. He was a member of the dwarf race. In return for the weapons he forged for the gods he was promised Thrud, Thor's daughter, in marriage. Thor did not like this arrangement and devised a test of knowledge to stop the marriage. He told Alvis that he had to prove that his great wisdom made up for his small stature. Thor prolonged the test until sunrise when the rays of the sun fell upon the dwarf; all dwarves turned to stone if touched by the sun's rays.
