Hârn has many human languages but most are derived from either ancient Jarinese or ancient Northern Lythian tongues brought to the isles by invading tribes over 1,000 years ago.
Each barbarian nation has a tribal language and Religious organizations have Temple tongues, some secret. The Gypsy Night People speak Elbythian.
The Elves (Sindarin), Dwarves (Khuzdul) and monstrous Ivashu all have their own tongue.
