Languages

Dune Whispers:  The language of a multiracial reclusive group of desert-dwelling nomads who don't interact much with civilized folk.

kel-'Renīyah:  The predominant language of the Two Kingdoms.  Ratfolk speak a variant called kel-Fahrenīyah.

The Laughter of the Desert:  Gnolls are not fashioned for human speech, but they can shape words around their natural sounds. In doing so, they speak two tongues at once; their yips and snarls and howls carry meaning amongst themselves that is hidden from their human listeners.  The language of the gnolls is, in truth, a dialect of Dune Whispers.  However, the gnolls are hardly a civilized group and tribes sometimes spend generations without interacting with each other.  Therefore, although gnolls from most tribes can understand each other (with quite a bit of effort), a character must name the specific tribal dialect they speak and understand when taking this language.

Vyarĭsitkŭ Językŭ: The language of the Aporuëna realm of Vyarisid.
