The Sons of the Perverter are a dangerous Chaos Warband that currently torments the Gallican Sector. The Warband used to be the Silver Lions Chapter which turned to Chaos. The Warband would become its current incarnation after it was taken over by the Chaos Space Marine Sorcerer Galkran Vornost, better known as Galkran the Perverter. The Warband has stopped acting as a combined unit since the death of Galkran, but they remain active within the Gallican Sector, operating individually or in small groups to cause pain and mayhem to all they come across.
