As well as a Boyar we also have this equally brutal-looking Boyarina who is ready to chop off some heads. I love that she's got her battle pipe at the ready, able to puff along as she slaughters her foes.
I think you can guess the Eastern European/Russian influences present here amongst the range! They are all hats and sparkly gold. I think it's a very fun alternative look for an army of Dwarves and matches well with their nature.
