Yidvi

Yidvi is the language of the people of Yidmark. Old Yidvian was the language spoken by the ancestors of both Valkavian and Yidvian alike. During the centuries of their separation, the tongues of both peoples diverged quite a bit to become modern Yidvi and Valkavian.

Writing System
Yidvian runes originated in the ancient tradition of yak-shaving. Yakherds would shave a variety of symbols into the fur of several of their yaks to indicate the history of the herd. A wide range of information was carried in these symbols, such as each field they stopped to graze in, the name of the Yakherd, the weather the yaks endured, and even how many yaks died and were born (as well as the circumstances around these events). It is thought that the earliest yak-shavings were inspired by the Gnomish alphabet which had begun to be used by the precursors to the Arthosian Empire during the late Silent Era.
