Gróa is a völva and practitioner of seiðr, the wife of Aurvandil the Bold.
In the God of War Series
The Lost Pages of Norse Myth
Gróa was a gifted seer who at some point married Aurvandil, a warrior. At some point, Thor asked for Aurvandil's help for a quest in Vanaheim. During the quest, Aurvandil apparently suffered from a bout of frostbite and had to be carried by Thor, who eventually lost Aurvandil in the tundra.
After his disappearance, Gróa traversed the Realms looking for ancient tomes that would augment her prophetic powers in order to discover Aurvandil's fate. In the process, Gróa became one of the most powerful seers in the Realms, so powerful in fact that even Odin often asked for her knowledge.
However, she still could not find out anything about her husband's whereabouts. After reading the runic incantations in an ancient tome, her powers became so great that she saw a vision about Ragnarök: a three-year winter (the Fimbulwinter) where the Realms quaked and the skies split, a horrible terror emerging with a flaming sword, an enormous wolf (Fenrir), Gods fighting against each other (The Aesir-Vanir war), and a white ghost from another land with his son.
Odin felt her vision, and paid a visit to Gróa's library, demanding for what she knew about Ragnarök. Gróa hesitated, and Odin threatened to kill her, just like Thor had killed Aurvandil. After hearing this, Gróa refused to tell Odin anything, before being strangled to death by Odin, who took all her knowledge in the process.
- Gróa was the first person to ever foresee the coming of Ragnarök.
