The Black Fang

The Black Fang was a group of assassins in Fire Emblem:Rekka no Ken who were located in Bern and led by Brendan Reed. They originally set out to do good (but illegal) work fighting corrupt nobles, but they were later taken over by Nergal and his morphs. The members of the Black Fang from when they were doing good are often referred to as the old fang. During the course of the game most of the fang is either wiped out or joins your side. Brendan Reed was the leader of the Black Fang until his death at the hands of Sonia, a morph of Nergal and his second wife.

Four Fangs
The four most powerful warriors in the Black Fang are the Four Fangs, who are made up of Linus, the Mad Dog, Lloyd, the Silver Wolf, Ursula, the Blue Crow, and Jaffar, the Angel of Death. Past members of the Four Fangs are the Death Kite, Jerme and Pascal, the Crazed Beast. Legault was once a member of the Black Fang, and his power was said to rival the Four Fangs.
