The Otter's Ransom

Odin, Hœnir, and Loki, travelling together through the world as they liked to do, came to a waterfall where an otter lay dozing over a salmon it had just caught. Loki, never able to pass up an easy kill, threw a stone and killed it on the spot — pleased with himself, the story says, for taking an otter and a salmon in a single throw. It is the mythology's most consequential piece of idle cruelty: a god killing an animal for sport, not knowing or caring what it was.

That night the three gods sought lodging at a nearby farm belonging to a magician named Hreiðmarr, and, making conversation, showed off their catch. The otter was no ordinary animal — it was Hreiðmarr's own son Otr, who spent his days fishing in that shape, as some men in the old stories could. The gods had killed their host's child under his own roof while asking for a bed. Hreiðmarr and his remaining sons, Fáfnir and Reginn, seized the three gods and bound them. Their lives, and their freedom, would cost a weregild: the otter's skin stuffed with gold, then covered on the outside until not one whisker showed.

What is a weregild, and why gold?

Weregild — literally "man-price" — was the payment Norse and wider Germanic law demanded in place of blood vengeance: a fixed compensation that let a killing be settled without a feud. Hreiðmarr's price was savage but lawful by the old rules, and it is the hinge the whole story turns on, because it forced Loki to go looking for an amount of gold that essentially did not exist above ground. He was released alone to raise it, on the promise that the other two gods would be held as hostages until he returned.

Loki went to Rán's net — the fishing net belonging to the sea-goddess Rán — and used it to catch the dwarf Andvari, who lived as a pike in a waterfall and guarded a hoard great enough to cover the debt several times over. Loki stripped him of everything, gold down to the last ring, and Andvari begged to keep one small item back: a ring called Andvaranaut, which had the power to breed more gold from itself. Loki refused and took it too. Cornered and furious, Andvari laid a curse on the ring and the whole hoard behind it: everyone who owned it from then on would be destroyed by it. Loki, rather than absorbing that risk himself, carried the curse straight to Hreiðmarr's door along with the payment — passing it on intact, the way he passed on most things.

The skin that would not quite cover

Back at the farm, the gods stuffed Otr's skin with the dwarf's gold and stood it up for Hreiðmarr to inspect. He walked around it and found one whisker still showing through, uncovered — the letter of the ransom unmet by a hair's width. Odin, who had taken a private liking to Andvaranaut and meant to keep it back for himself, was forced to give up the ring to close the last gap. The curse passed into the pile complete, every piece of it now belonging, by the world's own accounting, to Hreiðmarr's household.

It did not take long to collect. Fáfnir killed his own father within days for sole possession of the hoard, then withdrew to a wasteland called Gnitaheiðr and turned into a dragon to guard it — greed made literal, a man transformed by what he refused to share. His brother Reginn, cut out of the inheritance entirely, spent the better part of a generation raising and training a foster-son, the young hero Sigurðr, purely to use him as a weapon against his own brother. Reginn reforged the shattered sword of Sigurðr's father, sent him to kill Fáfnir, and planned to keep the gold for himself once the dragon was dead — a plan that ended with Sigurðr killing Reginn too, on the advice of birds who warned him he was next.

Downstream: the fall of the Völsungs

The gold rolled on from there through the whole tragic matter of the North: it passed to Sigurðr, then by treachery and love-magic to Brynhild and Guðrún and the Burgundian kings, carrying death to nearly everyone who touched it, exactly as Andvari had promised. It ends, generations later, sunk in the river Rhine, taken out of circulation by people who had finally learned what it cost to hold it. Three gods skipping a stone at an otter on a riverbank is, when the ledger is added up, the opening entry of the entire Völsung cycle — a war, a dragon, a dynasty, and a hoard, all invoiced from one careless afternoon.

In the primary sources

The story's oldest surviving telling is in Reginsmál, a poem in the Poetic Edda that frames the killing, the ransom, and Andvari's curse as backstory delivered by Reginn himself to young Sigurðr, setting up the saga to follow. The thirteenth-century Völsunga saga retells the whole episode in prose as the opening chapter of its sweeping account of the Völsung and Niflung families, and is the source most readers know it from today. Snorri Sturluson gives a third version in Skáldskaparmál, in the Prose Edda, where the tale exists chiefly to explain why gold is called "otter's ransom" and "Andvari's inheritance" in skaldic kennings — poetry's own footnote to a myth about a debt that was never really paid off, only moved along.
