In Forget-Me-Not Bombshell, the London Firm, ruled by the Butcher Brothers, takes center stage with Anya Volkov, the daughter of the Russian Bratva, jetting off to the UK to fulfill her marital obligations to Danny, the Butcher of London, commonly referred to as the unhinged twin. Becoming shackled to Danny is a death sentence, and Anya refuses to go down without at least sticking a knife in his back first.
Unlike the Greek Pantheon, the Bratva believe only that the Gods are real. It is both a spiritual and military order, and up until the Covenant Wars, the Bratva were the most feared soldiers on Earth, but after the Covenant Wars, they were banned, and now the remnants of their society operate in secret.
The leadership of the Bratva is based out of Moscow and is led by the Kalashnikov Brothers, two blond, blue-eyed Russian men, the spitting image of Vladimir Putin. The two manage their affairs through an all-seeing mirror that resides in a crystal ball. So what is it with the mirror and the Bratva? Why is it such a prominent plot point? Are they just a group of Russian Berserkers? Well, it all comes down to the Bratva being the only people in the pantheon of gods who don't have an obsession with human sacrifice - as human sacrifice isn't necessary for a God to manifest (unlike the Greek gods, who can't manifest without human sacrifice). If they can scare off everyone else, then they're in the clear.
The Kalashnikov Bratva are a very advanced cybernetic society, making them even more advanced than Earth's space race. In fact, they are the only known cybernetic race in the known universe, and they can pilot space far more efficiently than human beings.
