The Volkvolny is the flagship of Sturmhond's fleet. Tamar Kir-Bataar says that he captured it from a Zemeni pirate that was picking off Ravkan ships near Os Kervo, and liked it so much that he took it for his own flagship.
It is a sleek schooner that is fast and silent. Every inch of the ship is used; for example, the crew sleeps on the foredeck, in hammocks that can be rolled up and replaced by the gun. Since the ship is outfitted with every kind of Grisha, including a Corporalki healer, there is no need for a otkazat'sya surgeon onboard. Instead, the surgeon's cabin becomes Tamar's berth. It is just big enough for a chest and two hammocks.
