Krathic is the ancient language of the Kratheri people who originated on the Continent of Za'har.

Today, the language is seldom used and considered almost a dead language. Only a few Kratheri scholars and sages are familiar with its speech and writing, and it is illegal to either speak or write the language throughout the realm of Thûle. This language is usually encountered along the Kratheri Peninsula, and only spoken there rarely. It has been forcibly replaced by an eastern dialect of Thannish.

On Corwyn, Many ancient ruins and former Kratheri buildings of the lost kingdom of Kerathos still carry the written form of this language as inscriptions, but very few can read the symbols or decipher them. Only on the continent of Za'har is the language commonly used today.
