In this world, there are things of a truly barbaric nature. Women, tired of the tame above ground fighting arenas hear tales of a place where they can win huge paydays if they are willing to strip away their civility.
A place that rewards sadism, suffering and sin. A ring where two women enter, cloaked in their robes, only to remove them and show their naked forms for a bloodthirsty crowd. Where they engage in pugilism till one woman is left a shell of her former self. But even then, there is no mercy to be offered. No helping hand. No stoppage.
The fights only stop when one woman is truly broken and dead. Till then her foe can commit all manner of atrocities upon her in search of a bigger payday. This is the NFFB.
