They come from below 2025-11-12 #10

The sump-sea air was damp amidst the ruins, old hab-lights flickering on and off as the followers of the Redemptionist faith sat around an old tunnel entrance. There was an almost electric tension in the air, Julius had seen House Delaque's plans for this ruined hab-block within the dancing flames. He alone understood the secret utterances in the revving of chainblades, and the signs painted by embers through the sky. He knew that faithless dogs would be here today, for the Emperor himself had willed him to know, and he saw fit to beat them to the punch before they could pollute another space. 

And beat them to the punch he did. Without warning 3 members of House Delaque stepped from the tunnel. Their mouths agape with shock and fear as a promethium barrel was kicked over and set alight from the Faithful's holy weaponry. Two of them were instantly set ablaze, with one quickly falling over and fully catching alight. The crackle of fat falling into the flame filling the air as his body burnt away at the holy pyre of apostates.

The other two scrambled away, one screaming as the flames ate away at his flesh. Julius knew there were more after him, the flames told him so. The hisses and snaps of flesh screamed it in his ears, and he roared in triumph. Casting his arms open in a sign of welcome to those attempting to clamber through the tunnel entrance the pyre roared ever higher. Flashing through the tunnel entrance and singing those still trying to come through it. He let out a chime of laughter, joy, at watching these heathens cower away from the flames in fear, as the flame itself seemed to surround him, yet he remained unharmed. 

Then, through their meddling, those of House Delaque turned the lights off. The darkness around him grew oppressive, and even seemed to smother out the fire before him. For a moment, the air was still, the footsteps of his opposition grew louder as they stepped closer towards their goal. His mind raced as the flames grew still, he felt a pang of fear at his heart before the momentary darkness ended, a simple flicker of lights in an abandoned section of the city. Nothing more, nothing less. He and the faithful were in control, and there was little the agents of the House of Whispers could do about it. He charged forth into the flames, striking at and batting away the blows of a psy-gheist before casting him backwards into the tunnel.

The fighting dulled down shortly after this, with many of the to-be pillagers and looters being turned away by His righteous flames. Those who were not smited by holy ordnances escaping back through the flames and living to fight another day.
