Nerthus
Nerthus is the personification of earth.
She is a vanir goddess, with an all encompassing scope over fertility. She has say over anything that thrives on the land, whereas her now husband Njord encompasses all that thrives in the sea.
Following Ragnarok, she returns to Vanir to take rule of the realm along with her new husand Njord; the sea personified. Together they rule over the land and the sea; but not over its people. On this world, so lush with life; both Njord and Nerthus declared everyone equal upon Vanaheim, and gave the ruling of it to its people. Instead they have taken on a more nature based role, and retreated to the wilds along with her husband. They have not been seen for many years.
