Arkhan the Black commands the Ossiarch Bonereapers with unmatched necromantic power as the most devoted servant of Nagash. This formidable leader rides into battle atop his dread abyssal Razarak, surrounded by swirling deathly magic and flanked by disciplined ranks of Mortek Guard and towering Morghast constructs—a force of skeletal warriors and devastating supernatural entities ready to dominate the battlefield.

Inside the Null Myriad Phalanx you'll find Arkhan the Black, a Mortisan Soulmason, four Morghast Archai (buildable as Morghast Harbingers), and 20 Mortek Guard. Perfect for launching a new Ossiarch Bonereapers army or bolstering an existing force, this set integrates seamlessly with the Null Myriad Army of Renown from the battletome.
