Aurvandil was a renown warrior in Norse Mythology, and the husband of Gróa.
Norse Mythology[]
The names Aurvandil or Earendel (Old Norse: Aurvandil; Old English: Ēarendel) are cognate Germanic personal names, continuing a Proto-Germanic reconstructed compound *auzi-wandilaz "luminous wanderer", in origin probably the name of a star or planet, potentially the morning star (Eosphoros). Recall that also the word 'planet' means wanderer.

Aurvandil was a Norse warrior who was married to Gróa, a seiðr. At some point, Thor asked for Aurvandil's help for a quest in Vanaheim. During the quest, Aurvandil was intentionally killed by Thor. He returned to Gróa and lied to her about Aurvandil's fate, saying he suffered from a frostbite during a battle and had to be carried away, until Thor lost him in a tundra.
In search of her missing husband, Gróa started collecting ancient tomes and their runic incantations to augment her prophetic powers. In response to this, Odin hid the truth about Aurvandil's death with a spell.
Gróa was eventually killed by Odin after she refused to share her knowledge about Ragnarök with the Allfather. Odin revealed the truth about Aurvandil's death, and then proceeded to strangle Gróa, taking her life and her knowledge.
