Description

The Iron Warriors were masters of siege warfare and the crushing of enemy fortifications—and they followed their fallen Primarch into Horus's heretical rebellion against Sol and the Emperor. Eternal rivals of the Imperial Fists, they often felt overlooked despite their sacrifices. Perturabo's burning anger and jealousy escalated into an inferno that saw his Iron Warriors decimate and burn entire worlds.

Prone to replacing damaged or lost limbs with mechanical implants, the threat of an Iron Warrior siege is enough to bring systems to their knees. Raised on the warring planet of Olympia, Perturabo honed his sharp tactics and strategies there, but his efforts were never appreciated by the Emperor. Wracked by bitterness and hatred for being overlooked, the brutal pacification campaign on Olympia drove Perturabo into madness. His betrayal of his brother Warmaster Horus unleashed a wave of rage, iron, and destruction that struck the Imperial Fists, the Empire itself—and ultimately the Emperor.
