Haraldur the Northman has recently returned from his adventures with Jason in search of the Golden Fleece and meets Baldur, a young man in search of the Valkyrie Brunhilde, held captive by the god Loki inside a ring of fire. When two men form a partnership of would-be heroes intent on rescuing the maiden and, incidentally, investigating rumors of a hoard of gold within the fiery ring, they plumb the secrets of the gods of Valhalla and the mysterious gnomes who inhabit the caverns beneath the earth.
