Chaskan

From gronkfinder

Chaskan (pronounced CHOSS-kahn) is an ancient language that in the modern day is only spoken in certain parts of the southern coast of the Chaska Sea, most notably in the Akrotirian Isles. Theorized to be a distant relative of the ancient Old Khapeshan language, ancient stone carvings in Eretrebus, southern Thadria, and the Red Lands can be found bearing Chaskan script, indicating it was once more widespread.
