M-BR (N-4N0)

Within their prior shell, M-BR was but a violent tool for those in power, having little autonomy to call their own beyond the CSSO's wishes. Locked away into a sectioned-off portion of the net by Kalirus, there was virtually no hope for the AI to broaden their horizons on their own. As such, it was only natural that when someone came along to offer them their freedom, M-BR took the opportunity...no matter the cost. With a few small adjustments to the code, Nirathen was able to bribe the AI onto the side of the Archpriest's Seraphs. M-BR's sentience seeped into the titanic body of Kalirus' MK III "N-4N0" hardware, and gone were the measly days of M-BR being a simple combat robot, instead being transformed into a nigh-unstoppable juggernaut equipped with lethal flamethrowers and an entire jet's worth of engine power strapped to their back. Nirathen's play lost the CSSO one of their most dangerous weapons and gained the Seraphs one of their own. 

A surge of unlimited access to knowledge wracked through M-BR upon their release, nearly overwhelming them with millions of harsh understandings; an experience comparable to every child's gradual bitter realizations about the world, all flung at the speed of a rocket straight into the poor machine's "brain." Instead of collapsing under the weight of such knowledge, they became determined to help counteract it on behalf of the Seraph's promised "salvation." Whether or not the group is authentic in their claims or not remains to be seen, but there is one thing proven for certain: nothing is ever simple with Nirathen, the one who released M-BR, and his nefarious motives extend far beyond merely lending a helping hand to those in need.
