The dwarves were master craftspeople. One dwarf, Andvari, forged marvelous creations. He often took the form of a fish and, one day, he swam to the land of the water nymphs, who guarded mounds of gold. When the nymphs laughed at his appearance, Andvari grew infuriated and seized their gold. With it, he crafted himself a special ring. Iseult Gillespie shares the Norse myth of the cursed ring.
