Slavic was a language spoken by Eastern European and some German cities in the Black Centuries and following Traction Era. It is, as the name suggests, of Slavic origin, meaning it is decended from such languages as Russian, Romanian and even some Greek.

It probably has a different Alphabet to Anglish and Frankish, considering it's Russian decent. Many Ice Cities spoke the language, suggesting it orginated in the North-East of Europe.
