Specialists in the technological needs of their Legion, Techmarines are trained in the rites and secrets of the Mechanicum. They tread a fine line of loyalty between Legion and the Machine Cult of Mars but their duty comes above all other concerns, tasked as they are with overseeing the maintenance and manufacture of their Legions arsenal. Techmarines are often found in the heart of battle, repairing damaged vehicles and incanting words of supplication to beleaguered machine-spirits.
