Iron Warriors brush of daemonic attack

Despite the recent attack by the Death Guard, the Iron Warriors of Warsmith Stahl still refused to leave their fortresses, content to hoard their resources, munitions and military assets to themselves.
Having not only offended the disciples of Nurgle, the god Slaanesh now demanded Stahl fight, but as before, Stahl refused.

Outraged at being denied, Slaanesh sent its daemonic host to teach to stubborn Warsmith the error of his ways. On 2112.019M42 a host of Slaaneshi daemons ambushed Stahl and his bodyguard. Clearing the distance between the two forces rapidly the Daemons chittered and giggled as they threatened the mortals, in response, Stahl ordered his warriors acquire firing solutions while marching the slaves forward to block the daemonic charge. The Iron Warriors and their mortal slaves opened fire with Chaincannon, autogun and boltgun obliterating the Seekers and Fiends in a hail of shell and Daemonic gore.

The remaining Daemons struck the mortals in a single wave and literal fountain of gore erupted from the Iron Warriors mortal slaves. The mortal slaves died screaming, the few survivors desperately trying to flee but Stahl simply activated the slaves explosive collars, killing them and some of the Daemonettes. The Daemons dominated the battlefield and it looked for a moment like they would reach Stah, but rather than falter the Iron Warriors charged forward to meet them. Daemon were cut down in concentrated overlapping fire, Terminators, ordered to reinforce the position, teleported into the centre of the battlefield and added their weight of fire to the slaughter. Stahl himself charge the Daemon Prince leading the host and tore the heart out, capturing its soul.

Just as rapidly as it started, the ambush was over, the Slaanesh Daemons wiped out for the loss of expendable mortal slaves.

Over the coming days and weeks, reports began to come out of Minos and Enceladus. Daemon forges burned hot and troop transports ferried Astartes from their fortresses. Whatever had stirred them, the Iron Warriors were, once again, marching to war. The question was, who was the source of their ire this time?

Stahl sighed as he placed the Warp flask containing the heart of the Daemon Prince alongside the squealing flask of Marcus of the Emerald Serpent.

“Will they ever let us be?” the Warsmith asked to no one in particular.

At that moment the door to his sanctum whirred open as Norros entered with the data Stahl had ordered retrieved.

“The Dark Mechanicum concur with you Lord, it can be done”

Stahl closed his eyes, for a moment feeling the full weight of 10,000 years of ceaseless war and insane entities that called themselves gods. They had left the Eye for hatred, revenge, for freedom, but only found the insanity of a universe that worshipped a corpse that equalled the insanity of the Eye. They would all burn. Everyone that had crossed the IV would burn in the fires of his vengeance. He opened his eyes and glowered at his subordinate.
