It's either too far east or too far west for me, depending on which "home" I look from, for the north-south dimension to matter.
For all I know, it could be Argentinian or belonging to southern Norway, and maybe it's not the cryptic part after all!
If we take coinage to mean coining a term, we should look for terms that appeared specifically in the south. Ernil i Pheriannath? Holbytla? Incanus? Tark? Fell Riders?
Incidentally, is the password MELLON? If so, it's probably the most ingenious password to make!
