Skuld was one of the Norns, and she was also one of the Valkyries. Her name means necessity, and is related to Engl. 'scold', 'should', and 'shall'.

She appears in at least two Old Norse poems as a Valkyrie.

She saw valkyries
come from far and wide,
ready to ride
to Goðþjóð.
Skuld held a shield,
and Skögul was another,
Gunnr, Hildr, Göndul
and Geirskögul.

I will recite the names
of the valkyries of Viðrir (Odin).
Hrist, Mist, Herja,
Hlökk, Geiravör
Göll, Hjörþrimul
