Niðhad

He appears as Níðuðr in the Old Norse Völundarkviða, as Niðung in the Þiðrekssaga, and as Niðhad in the Anglo-Saxon poems Deor and Waldere.

[1] In Völundarkviða,[2] Níðuðr appears to be a king of Närke (the Njars) and captures Völund.

For revenge, Völund killed the king's sons when they visited him in secret, fashioned goblets from their skulls, jewels from their eyes, and a brooch from their teeth.

One day during a war expedition Niðung found out that he had forgotten his magic victory stone Siegerstein.

Velent later returned in disguise to Niðung's kingdom and gave the daughter a love philter.

The plan failed because the princess' magic knife showed her the danger before she had imbibed the potion.

Wanting revenge, Velent seduced and impregnated the princess and killed Niðung's two sons, making table ware of their bones.

To help his brother, Egil shot birds and collected their feathers, of which Velent made a pair of wings.

In the poem Deor there is a stanza which refers to an Old English version of the legend of Welund and his captivity at the court of Nithad: The third stanza of Deor is ungrammatical and obscure in meaning, but some commentators have inferred that it focuses on Niðhad.
