After reading the Felwinter grimoire card. A few things about Felwinter were revealed. In a time before the consensus there were warlords who had the power of light and ghosts. They took territory and sometimes abused the land and its people. The iron lords sought to unify everyone. Felwinter went to a warlord Titan named Citan as an envoy of piece for the iron lords. After a heated debate Citan became enraged and tried to hammer of sol Felwinter. But before he could Felwinter aerial shoulder charged him. Apparently Lady Jolder taught him how to do it. Citan's ghost resurrects him and Felwinter kills him again with his famous shotgun Felwinters Lie. This time he killed Citan's ghost as well so Citan stayed dead as he was guardian. With Citan dead permanently, the iron lords gained his territory and freed it's people.
