In a separate story, an ataman of the Don Cossack Host named Andrei Shadrin led a band of three Cossack sotnias to the Kumyk lands, founding a frontier town called 'Tersky' (location uncertain). This may have been partially motivated by his tense relations with Yermak Timofeyevich. He subsequently founded Andreyevo (the modern Endirey), which was said to be named for him.
