These are all the tongues spoken by the peoples of the Avernan continent, both secret and open. Secret languages are marked in red, and may only be taught to members of a specific group to which the language belongs.
Arkash – The ancient language of the orcs. Since the Evari Republic's canonization as the one and only client state of the Valusan Imperium, it has been abandoned in public or formal settings, and is only spoken in private, between orcs.
Atiri - A secret dialect of Elari, the Valusan lingua franca. Used to record the information that Jan'Atir's followers so desperately pursue in the Collegiate libraries. Can only be learned by Clerics, Paladins, or Inquisitors of Jan'Atir, Conqueror of the Mind.
Boskar - The language that the nationless druids normally speak. Some innate magic in its syllables allows unfettered speech with animals, plants, the wind, and other aspects of nature. Replaces Druidic, and can only be learned by Druids.
Caril – Language of the Alarusian halflings. Frustrating to learn as a result of its complex grammar.
Elari - Lingua franca of the Valusan Imperium. Spoken mainly by Valusan humans and elves, but typically is learned by those who live near or do business with Imperial Provinces.
Einjalr – Language of the Stygian island peoples. As a result of its similarity to Norgranr, the Korvathi language, speakers of Einjalr are easily understood by natives of the Baronies.
Marish - Language of the unholy devils of the Nine Hells. Curiously, it is also spoken on occasion by intelligent denizens of the Dark Plane. Replaces Infernal and Abyssal.
Norgranr – Language of the Korvathi humans, halflings, and dwarves. Usually learned in conjunction with the student's race's native tongue (e.g. humans learn Valman, halflings learn Caril, dwarves learn Tebarach).
Tebarach – Language of the Montish dwarves. Spoken by natives of Monthold, or any that wish to do business with them.
Umbari - The language of arcane magic, spoken and written by wizards the world over. Replaces Draconic, and can only be learned by wizards.
Valman - Language of Orinari, Colinari, and Garish humans and halflings, comprised of three major dialects; Orinari, Colinari, and Garish. Most residents of northern nations (i.e. north of the Evari Republic) understand this language.
