Randvér or Randver was viceroy of Sweden and the son of the Varangian Radbjart and Aud the daughter of Ivar Vidfamne. He was married to Ingild, the daughter of an unknown Swedish king. He was succeeded by his son Sigurd Ring.
According to Hervarar saga both Randver and Harald Hildetand and were the sons of Valdar and Alfhild, the daughter of Ivar Vidfamne.
When his brother Harald, had reclaimed Götaland (or Gotland depending on the manuscript), Randver died hastily in England, and was succeeded by Sigurd Ring as the king of Denmark (probably as Harald's viceroy).
So the king set forth this journey in seemly wise, and they fare till they come to King Jonakrs abode, and behold Swanhild, and have many thoughts concerning the treasure of her goodliness.
Yet because of the kings furthering, and all the matters that went herewith, is the wooing accomplished; and Swanhild went to the ship with a goodly company, and sat in the stern beside the kings son.
Good seemed that word to the heart of the kings son, and he spake to her with sweet words, and she to him in like wise.
