Doing it for "nyrond", I discover that this is still current as the name of one of the countries in the D&D realm of Greyhawk. As far as I'm aware this is parallel coinage: I had the first ever Greyhawk supplement to the original D&D set not long after it first came out, but as far as I remember it didn't mention Nyrond. I don't remember where the word first came from, but it's far too late for either of us to change it now....
