Draupnir


In Norse mythology, Draupnir is a gold ring possessed by the god Odin with the ability to multiply itself: Every ninth night, eight new rings 'drip' from Draupnir, each one of the same size and weight as the original.
Draupnir was forged by the dwarven brothers Brokkr and Eitri. Brokkr and Eitri made this ring as one of a set of three gifts which included Mjöllnir and Gullinbursti. They made these gifts in accordance with a wager Loki made saying that Brokkr and Eitri could not make better gifts than the three made by the Sons of Ivaldi. In the end, Mjöllnir, Thor's hammer, won the contest for Brokkr and Eitri. Loki used a loophole to get out of the wager for his head and Brokkr punished him by sealing his lips shut with wire.
The ring was placed by Odin on the funeral pyre of his son Baldr:

Odin laid upon the pyre the gold ring called Draupnir; this quality attended it: that every ninth night there fell from it eight gold rings of equal weight..

The ring was subsequently retrieved by Hermóðr. It was offered as a gift by Freyr's servant Skírnir in the wooing of Gerðr, which is described in the poem Skírnismál.

In popular culture

Draupnir is represented as a card in the Yu-Gi-Oh Trading Card Game. It has an effect that mimics the multiplication ability of the mythological version. If it is destroyed by another card's effect, you can add another "Nordic Relic" card to your hand.
DRAUPNIR was revealed as the key to a website that Neal Caffrey and Mozzie used to view their stolen Nazi U-boat treasure in "Taking Account", the seventh episode of the third season of White Collar.
It also appeared in episode 11 of as a tool to seal Loki's spirit.
The Draupnir is never called by name but is simply known as Odin's ring in the first three books of the Witches of East End novels. This ring allows the wearer to teleport to any place of the nine worlds, and a copy of equal power was once owned by Loki before it was destroyed by Freya.
