I couldn't remember what name I'd come up with for the living metal in the Lyriaverse, just that I couldn't call it mithril. And I couldn't find the name I'd come up with for it in any of my notes (I know I had one!). So I said, "Fuck it!" and came up with a new name. The new name is "ilufim," which is pronounced Élő fém, which is Hungarian, meaning "living metal." I was going through a whole bunch of different ones on Google Translate, listening to them, with the intention of mixing languages, when this one came up. It sounded too awesome to change, so yes, there's a purposefully respelled version of a Hungarian phrase for its name.
