Both valkyries appear in Heimskringla where they seem to be the same being, and are otherwise listed separately in the valkyrie lists in the Poetic Edda poems Völuspá and Grímnismál, the longer of the two valkyrie lists in Skáldskaparmál yet Skögul appears alone in the shorter of the two.
Haakon and his men die in battle, and they see the valkyrie Göndul leaning on a spear shaft.
Göndul comments that "groweth now the gods' following, since Hákon has been with host so goodly bidden home with holy godheads."
Haakon hears "what the valkyries said," and the valkyries are described as sitting "high-hearted on horseback," wearing helmets, carrying shields and that the horses wisely bore them.
The poem continues, and Haakon becomes a part of the Einherjar in Valhalla, awaiting to do battle with the monstrous wolf Fenrir.
