Volsunga Saga - Chapter 14
REGIN'S TALE OF HIS BROTHERS, AND OF THE GOLD CALLED ANDVARI'S HOARD.
THUS the tale begins," said Regin, " Hreidmar was my father's name, a mighty man and a wealthy: and his first son was named Fafnir, his second Otter, and I was the third, and the least of them all both for prowess and good conditions, but I was cunning to work in iron, and silver, and gold, whereof I could make matters that availed somewhat. Other skill my brother Otter followed, and had another nature withal, for he was a great fisher, and above other men herein; in that he had the likeness of an otter by day, and dwelt ever in the river, and bare fish to bank in his mouth, and his prey would he ever bring to our father, and that availed him much: for the most part he kept him in his otter- gear, and then he would come home, and eat alone, and slumbering, for on the dry land he might see naught. But Fafnir was by far the greatest and grim- mest, and would have all things about called his.
"Now," says Regin, "there was a dwarf called Andvari, who ever abode in that force, which was called Andvari's force, in the likeness of a pike, and got meat for himself, for many fish there were in the force; now Otter, my brother, was ever wont to enter into the force,  and bring fish aland, and lay them one by one on the bank. And so it befell that Odin, Loki, and Hoenir, as they went their ways, came to Andvari's force, and Otter had taken a salmon, and ate it slumbering upon the river bank; then Loki took a stone and cast it at Otter, so that he gat his death thereby; the gods were well content with their prey, and fell to flaying off the otter's skin; and in the evening they came to Hreidmar's house, and showed him what they had taken: thereon he laid hands on them, and doomed them to such ran- som, as that they should fill the otter skin with gold, and cover it over without with red gold; so they sent Loki to gather gold together for them; he came to Ran, and got her net, and went therewith to Andvari's force, and cast the net before the pike, and the pike ran into the net and was taken. Then said Loki —
'What fish of all fishes,
He answered —
"Andvari folk call me,
 "So Loki beheld the gold of Andvari, and when he had given up the gold, he had but one ring left, and that also Loki took from him; then the dwarf went into a hollow of the rocks, and cried out, that that gold-ring, yea and all the gold withal, should be the bane of every man who should own it thereafter.
"Now the gods rode with the treasure to Hreidmar, and fulfilled the otter-skin, and set it on its feet, and they must cover it over utterly with gold: but when this was done then Hreidmar came forth, and beheld yet one of the muzzle hairs, and bade them cover that withal; then Odin drew the ring, Andvari's loom, from his hand, and covered up the hair therewith; then sang Loki —
"Gold enow, good enow,
"Thereafter," says Regin, "Fafnir slew his father and murdered him, nor got I aught of the treasure, and so evil he grew, that he fell to lying abroad, and begrudged, any share in the wealth to any man, and so became the worst of all worms, and ever now lies brooding upon that treasure: but for me, I went to the king and be- came his master-smith; and thus is the tale told of how I lost the heritage of my father, and the weregild for my brother."
So spake Regin; but since that time gold is called Otter-gild, and for no other cause than this.
 But Sigurd answered, "Much hast thou lost, and exceeding evil have thy kinsmen been! but now, make a sword by thy craft, such a sword as that none can be made like unto it; so that I may do great deeds therewith, if my heart avail thereto, and thou wouldst have me slay this mighty dragon."
Regin says, "Trust me well herein; and with that same sword shalt thou slay Fafnir"
