Comprised of mutated 'Viper Knights', the Order of The Flaming Sun was a chivalric order of monster hunters which once resided within the city of Shariz. Led by the secretive Ser Menge, the order was mainly tasked with uprooting infestations of monsters and beast which spread across the desert. Despite early noble intent, the order quickly began to devolve into fanaticism, oftentimes disregarding human life in pursuit of their goals. With the return of the Primarchs of the Sun at hand, the order fell into service to Primarch Arkhan, who operated from their subterranean crypt for a time, attempting to harness the power of The Great Ankheg. It is believed that the orders mutated knights were created from dark rituals performed upon the decaying corpse of The Great Serpent may suns ago.
