Frodi. The son of Frey, a god of peace. Under his direction two giantesses turned a pair of magic millstones which ground out gold according to his wish and filled his coffers. Excited by greed he forced them to labor, allowing rest only long enough for the singing of one verse. When Frodi, himself, slept, the giantesses changed their song and proceeded to grind out an army of troops to invade the land. These troops represent the Vikings.
