This is sort of buried in RS' old lore. For whatever reason, use of the Infernal Language survived in Burthorpe even after the fall of the Zarosian Empire. My guess is the mountainous terrain isolated it from other cultural influences. In any case, when formally speaking to an Imperial Guard, the language, as understood by humans, is indentified as "Latin." I believe "Latin" just the word in human "common" for the infernal language.
