Nehabrak
“Nehabrak once an adept of the Pyrae Cult and skilled pyrokinetic of the Thousand Sons legion. Though after the Battle of Prospero and the complete corruption of the Legion from Ahriman, Nehabrak began to experiment within the Cult of Mutation to see if the future of humanity is set in stone. He found many answers through the Chaos created drug called Fleck and wanted to spread his gifts to all of mankind who he believes to be shackled by the false hopes of the corpse emperor. Leading his warband called The Vitrifiers in the realms of the Imperium he leaves nothing, but satisfied cultists and the vitrified remains of his rivals in his wake. He is the Flaming Serpent who will set mankind free, for they will all will be turned to glass.”
