User blog comment:SingMeloetta/Theory:Where is Elza From?/@comment-26426093-20170616011444

Nice theory about her nationality being Belgian, but before reading this blog I'd already narrowed it down to either Italy or France.

If we are talking about her royal bloodline on the other hand, then I could also point out that Monaco and Luxembourg are also strong candidates; both countries are still monarchies and share various cultural links with France and Belgium/Germany respectively. Both of these countries, despite their tiny size also happen be among the richest per capita in all of Europe, which explains how Elza (or her parents) could easily purchase and modify any cruise ship and turn it into Venus Ark.
