I can't recollect the term nor find it in any norwegian dictionaries. If I do a websearch on it, I only get scattered stuff about a Black Metal band.

Given those bands' tendency to favor Norse mythological names and the old Norse words in general, you might be better off asking for a translation from Icelandic (which I don't speak, unfortunately, though I might be able to ask my grandmother who grew up there :)

Icelandic, due to being so isolated after being settled by vikings originally, is about the closest one can find to old norse nowadays. It does have sort of an 'old norse' sound to it (either ferdazyn or ferdasyn) so I reccomend you try that. Good luck. :)
