The Queen's Shadow
Each region and country has its own language though some have similarities and are very close. There is no ‘common’ language between the lands.
A character may have a variety of levels of understanding for any given language.
Kel’edonian – Most likely your Native Tongue.
Merthdonian – may have some knowledge of this if family is merchant, diplomat, noble etc.
Southern Tribes – a collections of dialects of one language “Dyshanian” Which ever form of Dyshanian you speak you can understand all with only a few words which are unique to each tribe.
Ancient Rythanian aka witches tongue – Rarely heard or learnt unless taught by the order of the sisters few outside the order have any understanding of this tongue, only shadows are taught the language in Kele’donia but that is not generally known.
Herdonian may have some knowledge of this if family is merchant, diplomat, noble etc.
Teraifanian may have some knowledge of this if family is merchant, diplomat, noble but it is less common to trade and travel here due to the civil wars.
