Created and woven into reality by God Kings who tired of addressing their subjects in different tongues, this language forces itself into the minds of all those who inhabit the Outer World. Most dislike speaking such an intrusive thing, thus its demeaning label.
The language of the sun and all things Light. Its sound is powerful and direct when spoken properly, with every sentence sounding like a decree.
Used the dead, forsaken and duplicitous. Dark Tongue is generally soft spoken and discrete, though it makes even horrors from beyond seem tempting.
The melodious tongue of those who dwell and sail between night and day. Famous for it's lengthy methods of explaining even the simplest of things.
The language of the Buried Kingdoms is more malleable than most; it is guttural but pleasant when spoken traditionally but humorous and rapid coming from Goblin dialects.
Perhaps the first language (perhaps not) this haunting speech is closest to Fade Song, save for that it resembles poetry rather than music. Elves, Fairies and the Unshaped use it in various meter.
The language of old Akenia, it now sees use primarily when researching ancient tomes and occasionally within esoteric magical societies. It is a flowery, valorous speech and often mourned by linguists around the world.
This language is compromised of simple one and two syllable words that relay information with alarming efficiency. It makes it surprisingly easy to translate via manual, much to the relief of Junkers the world over.
