The sight of machine bodies moving freely everywhere around him sent a turmoil of emotions through Vulkan.
He had remained here ever since boarding the Sword of the Void.
Vulkan still felt wary and uneasy around these machine bodies that called themselves Men of Iron.
His Progeny's past experiences had taught him the dangers of these silicon-based intelligences.
Yet he could detect no lies in anything the Men of Iron had told him.
Among the Primarchs, aside from Lion El'Jonson, the Lord of Drakes probably understood the threat posed by these iron clanks most clearly.
Before the Emperor had unified the Imperium, long before Vulkan had returned, his gene-Progeny had personally taken part in the brutal wars on Terra.

Tens of thousands of the Sons of the Fire Dragon, then still known as the Dragon Knight Legion, had followed the Emperor's orders and fought the machines of the Men of Iron left behind on ancient Terra.
Those terrifying war machines had lain dormant deep beneath Terra alongside their control core and factories. An accidental intrusion had triggered their alert, and under the control of the Storm Corridor Intelligence Nexus, they had dealt these sons of the Emperor a near-devastating blow.
Alloy bodies that neither bolter fire nor melta weapons could damage had rampaged through what had once been the Salamanders.

But in the end, those machine bodies had torn both his Progeny and their equipment to pieces.
Before those terrifying machines, the mighty Astartes had been as fragile as rag dolls.
Ceramite armor had become
