Valtian was the language of the Valtian Empire, which has survived in a great many extant works and other texts from the time of the empire. It is now the language (in the form Neo-Valtian) of scholarship and international communication in Epiros and Notios, and is in many places the language in which religious rites are conducted.

The Valtians left a sizable corpus of their written language, but the script used to write Valtian is unlike anything used in southern Epiros or Notios today, largely because of the Pallatians imposing their own script (brought over from Anatios) upon the "civilised" nations of south-eastern Epiros after the founding of Lokren. Scholars and sages have been able to decode the initially-mystifying alphabet, though, and Neo-Valtian is now used by the highly educated and the upper class to transcend the language barrier between scholars and diplomats of different nations.

When spoken out loud, some Valtian words bear a superficial resemblance to Lokrenian, due to the descendant languages of Valtian spoken in Epiros that were absorbed into the language of the ruling Lokrenians during the Age of Dominion. For much of Lokren's history, the majority of the population spoke one of the Epirian languages descended from Valtian, but as the number of Pallatian settlers grew and the empire expanded, so too did the number of Pallatian (and Ardryn) words that found their way into the vernacular of the kingdom. Each language influenced the other, but due to the greater part of the population speaking an Epirian tongue, the original vernacular was largely able to hold its form. Modern Lokrenian thus bears more than a passing resemblance to Valtian, even though much of its vocabulary has a completely separate origin.
