*Special DM permission required to learn these languages.
† There are many ancient languages, some are archaic forms of existing languages, some are dead languages with their own alphabets and structure. Only by studying examples of such languages, or by studying texts written about them, may such languages be learned.
A special note about the language of orcs and goblins, etc…
These creatures (orcs, goblins, and even ogres), specifically ones who dwell in areas outside their homeland, speak Gobtalk. This is a catch-all language for those creatures who either migrated to the Free Kingdoms during the last age, who are descended from the Ovar-Kin (from On-Vani-Ovar, the goblin nation), or are descended from the Nokol-Orai (the orcish invaders from the southern continent during the War of the Standard). The predominant language of these humanoids was adopted primarily due to the fact that such creatures a) are short-lived, b) are not intelligent enough as a race to retain more than one language, and c) these creatures for the most part, have become isolated from their parent nations and hence have lost such tongues to the melding of cultures.
