Viðar is the son of Oðin and the jotuness Grídr. Known as a highly skilled warrior he is cited as being nearly as strong as Þor. We do not have a lot of surviving lore about him aside from the one story in Ragnarök. Below are two prayers I composed to honor him after he contacted me for a chat. Funnily enough it happened in a grocery store where he got really excited about waffles for an offering. Go figure!
Viðar, silent-Ás
Son of Oðin, Shoe-wearer
Counselor for the All-father
Avenger, Huntsman, Woodsman
I honor you this day
Walk with me that I show wisdom in all my counsel and bring honor to my path
Warrior, I give you hail and thanks!
A second invocation looks like this –
Viðar, son of Oðin – All-father,
Silent Ás, Huntsman, Woodsman, Counselor
You whom avenge your father,
Guide well my path as through the woods of life I travel
Lend your counsel and aid as I face my own trials.
Great Warrior, Hail!
