Pyotr

Pyotr is an enterprising peasant from Aleksandrovka. He befriended Amadeo de Luca after the latter's virtuoso performance at Gavrilo's funeral, and brought him to his house for food, drink, and a bath. There, he threw his daughter, Darya, at the foreign VIP, with whom he also wants to go into some sort of business. Ever since then, he has been trying to track Amadeo down, so far, without much success.
After the group returned from Zmiihorod, Pyotr had a long chat with Lada Kolova concerning the state of his daughter.
After the group felt like they had to leave town following Irina's death, Pyotr's family was also expelled from the village (partly, it seems, for his connections to Lada and the rest of the group. He found his way to Vashti's cave a little ways outside Aleksandrovka, where he once again encountered the group, which had returned from the Old Watermill. Tentative agreements were made for them to safely conduct his family to Vyshemila. 
Pyotr has a wife, and aside from Dasha, six other children, who all left the village with him.
