Sigrún

Sigrún (Old Norse: /ˈsiɡˌrũːn/; "victory rune" ) is a valkyrja in Norse mythology; the lover of the hero Helgi Hundingsbane.

Poetic Edda
Sigrún's story is related in Helgakviða Hundingsbana I and Helgakviða Hundingsbana II, in the Poetic Edda. The original editor annotated that she was Sváfa reborn.

Sigrún is meeted by Helgi Hundingsbane when she leads a band of nine Valkyrjur:

The two fall in love, and Sigrún tells Helgi that her father Hǫgni has promised her to Hǫðbroddr, the son of king Granmarr. Helgi invades Granmarr's kingdom and slays anyone opposing their relationship. Only Sigrún's brother Dagr is left alive on condition that he swears fealty to Helgi.

Dagr is however obliged by honor to avenge his brothers and after having summoned Óðinn, the god gives him a spear. In a place called Fjǫturlundr, Dagr kills Helgi and goes back to his sister to tell her of his deed. Sigrún puts Dagr under a powerful curse after which he is obliged to live on carrion in the woods.

Helgi is put in a barrow, but returns from Valhǫll one last time so that the two can spend a night together.

Sigrún dies early from sadness, but is reborn again as a valkyrja. In the next life, she is Kára and Helgi is Helgi Haddingjaskati, whose story is related in Hrómundar saga Gripssonar.
