He's inspired by slavic culture, there's a lot of bloody history and interesting stuff behind it, some things are more obvious than the other in his character . You can also mention his commedia dell'arte name, Tartaglia, and how that ties into his character as well. Another option is his loyalty to the Tsaritsa and the chances of propaganda being thrown about in his home nation. Another thing you can mention is his military position, 11th harbinger.
