The Turkish Empire moved Muslim nomadic tribes from Asia to this region to replace its Bulgarian population and culture.

In his History of Gabrovo as a settlement with a special martial statute, 12th to 19th centuries, Boris Stanimirov pointed out how freedom-loving and confident Vardun Bulgarians were.

With regard to this is the interpretation of Stefan Chureshki in his publication "The List of Bulgarian Princes", where he talks about a tzar’s inscription from 1281 found near Vardun.

Vardun is in the north of the Gerlovo area, a valley enclosed by the Balkans from the south, and by the Preslavska mountain from the northeast.

A modern interpretation (based on unknown premises) claims that Tsika was the capital of the tribe of Severs.

According to legend, locals believe that the spring water can cure illnesses, including kidney and stomach problems.
