History of North, Vidar (or widar) son of Odin Information

[knowledgeOfNord]

hi everyone, I was looking for information on the god Vidar, but the only source on the web seems to be wikipedia ... needless to say, I was looking for more detailed and accurate information about the god and maybe if he appears in Jos's list with another name, or if this god mentioned in the Ragnarok is just an allegory.
