The question is whether Viðarr was conceived specifically to avenge Odin's death, as Vali was conceived to avenge Balder, or if he was groomed after birth to be the God of Vengeance, after Odin talked to the seeress. Vali kills Hodr at one day old, but Víðarr is spoken about in other tales, and is therefore not born immediately to perform a specific task. When Thor journeys to see Geirrod he stays with Gridr, who is at that point in cosmic history said to be the mother of Víðarr the Silent. Being a consort of Odin she helps Thor by giving him her staff, belt of strength and iron gloves. In Skaldskaparmal, Víðarr is sitting on Odin's benches, in his great hall, when Loki asks Odin if he is not welcome in his hall. Odin asks Víðarr politely to get up and allow Loki to sit down. Víðarr does as his father asks and lets Loki take his place on the bench. Víðarr also pours Loki a drink which leads to the rude toasts that the trickster makes.
Víðarr' s silence might be a ritual silence, in much the same way that his half brother Vali did not wash, or comb his hair, until he had avenged Balder. It is possible, I would say probable, that Víðarr will not utter a single word until after he avenges Odin' s death by killing the wolf - beast Fenrir. After he kills the great beast I am sure the " Silent God " will have plenty to say.
Víðarr is said, in Grimnismal to live in a land overgrown with brushwood and tall grass. It is here that Odin' s son : " Gets off the back of his mare. " This also shows once again that he was born long before Ragnarok began, and was not an " instant " fast tool of vengeance as was Vali.
Víðarr is said to be second in strength to only Thor. In his battle with Fenrir it is stated that he will take hold of the upper jaw of the wolf, and tear apart his gullet ( The throat ). The Silent God holds down the lower jaw of the great beast with a very special shoe. This shoe has been constructed by every piece of leather that people have cut out of their shoes, and thrown away as scraps. I interpret this to mean that not only does Víðarr take vengeance on Fenrir for killing Odin, but also, in a small way, we here in Midgard have a roll in the killing of the beast that takes the life our All - Father.
The great God of Vengeance will survive Ragnarok, he will not be harmed by Surt's fire, or by drowning waters, as will his half brother Vali, Thor's sons Magni and Modi, and Balder and Hodr. The lands of Asgard will be re - populated by the Sons, and grandsons of the All - Father.
I see Víðarr as a stoic God, who like Heimdall is very observant of his surroundings. He is silent out of a warriors ritualistic code, and he trains every day for the one event where he will shine greater than Sunna. He is a patient God who knows not exactly what day the terrible event will take place, but who must be ever ready to take his place in history, and lore. He is a God who will " speak " with his actions, and who will honor his father, and all of Asgard with his strength and resilience. He is Víðarr the great God of vengeance !
