Freya

Vanir-born Queen of the Aesir and leader of the Valkyries
It is said that in order to end the war between Vanir and Aesir, Freya married Odin. Whether this was out of love or because of politics is unknown. What is known is that she loves her son Baldur and would do anything for him. So once the immortal Baldur was killed she rallied her Valkyries to wipe out the traitor Loki and her forces of Ragnorok
