Age of Sigmar
Era of the Beast
After the disturbances in the Realm of Ghur during the Era of the Beast, he has led several great crusades into Thondia through Vensoth Bay to free the lands of perceived tyranny and monster of anybody not part of the Bileblood Court. These crusades as led them to fight the Orruk Warclans, the tribes of Chaos and any beast they chance to encounter.
Marrowblade and his powerful army can be enlisted for aid by other forces beyond the Bileblood court, but such envoys often risk getting eaten or infected by the delusions of the king, which only the strongest minds can resist.
