The Ossiarch Bonereapers faction in Warhammer Age of Sigmar is a relentless and disciplined army of skeletal constructs, meticulously crafted by Nagash, the Supreme Lord of the Undead, to enforce his iron will across the Mortal Realms. Unlike typical undead, the Bonereapers are not mere reanimated corpses but intricately designed warriors, forged from the bones of fallen heroes and villains alike, animated by the dark sorceries of their creator. Each soldier is a masterpiece of necromantic engineering, combining the strength and skill of countless warriors into singular, formidable beings. The Ossiarch Bonereapers are led by the indomitable Mortarch of the Necropolis, Katakros, and are driven by an unyielding purpose: to collect the tithe of bones owed to Nagash. Their legions include the elite Mortek Guard, the terrifying Kavalos Deathriders, and the hulking constructs known as Gothizzar Harvesters. With a strict military hierarchy and an unwavering dedication to their grim task, the Ossiarch Bonereapers march with precision and efficiency, embodying the cold, calculated vision of Nagash’s dominion over life and death.
