You guys are awesome--thank you so much!

Hinoto-no-Ryuji, I've taken it as a kind of "everyone knows the Common Language" handwave, since other race-specific languages have always been implied with the naming conventions, but you don't actually see characters speaking in those tongues. Also, even before this expansion, a number of Othard-related characters would often say something like "in our tongue, we would say X," where the X would often be a recognizable Japanese word for us. The NIN job storyline stands out to me as an obvious example, because Oboro gives you the password to enter the dojo and tells you not to worry about what it means. XD (I believe it's kaede but it's been awhile. But as a joke I think you have the opportunity to say kaeru instead!)
