Russian Empire, ancient noble families that own power, which is akin to magic, balls, champagne and the crunch of a French bun... There are two of them. One is young and the other is almost old. One was born in this world, the other arrived in it from afar. One is led by revenge, and the other by paternal duty. Perhaps these two are destined to change the whole world. And perhaps not. One of them is a terrorist. And the second is his own clan.
