Most interesting lesser known gods?
Norse Myth is one of those great works that I find profoundly interesting because of how much we have to work with, and how much you can extrapolate from the linguistics, the traditions of the Norse and their habits, and the names of places and epithets of characters. It kind of opens up doors to lesser known characters and deities that people don't necessarily talk about.
To me, it's characters like Ullr or the "Mightest Aesir" mentioned exactly once in a stanza. I find them interesting, the two in different ways, because of how little we know about them. We can only speculate or work with what we know of them.
Do you guys have any favourites like that? Or lesser known details about the gods?
