Bronze Fang was once the leader of the of the anarchist group Maelstrom, who preached the destruction of the Imperium's government. In return, he would have them replaced by Warlords, leaving the land in blood-soaked anarchy.
There were beasts that backed him, sickened by the new Emperor and clearly corrupt government. These beasts became the group known as Maelstrom, and they made their first move in Bugs of 1732. Sinking an Imperial vessel, they sent back a sole survivor to tout the skill of their attacks.
