Khufuan (Koo-foo-an)

Unless you come from the country, you will have a hard time understanding spoken Khufuan as it is nothing like the other languages of Kaldra but the written language is moderately simple hieroglyphs that can be interpeted in multipule ways depending on context.
The problem with the language itself is only when you are traversing the Khufuan Empire, whose people don't take well to outsiders and therefore don't usually learn other languages.
