Vali and Narvi: adults or children?
Some writers depict Vali & Narvi as children. Others depict them as adults... So what's the truth?
Well, officially, Vali & Narvi's ages are never plainly stated. The Eddas only say they are Loki & Sigyn's sons.
However, I do believe there Snorri left us some clues in different stories - maybe not directly about Vali & Narvi, but through some other characters, we can make our own opinion.
As far as I'm concerned, I see Vali and Narvi as young kids, because it makes sense. They are often aged up because people don't want to see their favorite gods killing children in such a gruesome way. Same reason why they are erased 🙄 Another reason why is because writers switch up Angrboda and Sigyn's places, making Loki meet Angrboda after Sigyn… Which was never the case. When Angrboda was introduced after the 12th century, it was pretty clear she was supposed to be his first wife, not a mistress 🙄 To anyone who read the Eddas and the sagas, it's pretty obvious because it's implied. Hel, Fenrir and Jormungandr are all adults. Hel has lovers, Fenrir has kids, Jormungandr is grow and has cameos in some of Thor's stories. I also believe they're kids because of the way Snorri treats the other kids of the gods. As I said, the 3 special kids got grown up stuff of their own, but they're not alone in that
Forseti, Baldr's son, has his own title and hall. Same for Ullr, Sif's son. One of Thor's sons even kill a giant. And Thrud has a Dwarf boyfriend and becomes a Valkyrie. But Vali and Narvi? Nothing about them, except for their death. It makes me believe it's because they just did not have the time 😭 All I can say is that I'm 💯 convinced their older siblings adored them and that even though they were badly treated by the gods, they accepted their fates, but once their little brothers were butchered, all hell went loose and Ragnarok truly started.
