Extremely durable and heavily armed Canticles of the Omnissiah combat walker unit.
Kastelan Robots are ancient monstrosities that stamp to war, each an unliving giant assigned a deadly purpose by its master. Soulless, these metallic golems are given thought only by the doctrina wafers in their recessed chestslots and the Cybernetica Datasmiths that program their every move. These machines are walking relics from aeons past, and all the deadlier for it—the air nearby thrums with power, bullets ricocheting from repulsor fields that glow like golden cages around them. Volleys of phosphor blasts and promethium incinerate their foes wherever they may hide, and crushing fists bring ruin wherever they strike. The violence meted out by each maniple is as inspiring to the Omnissiah's faithful as it is terrifying to his foes.
