The ordeal fleeing on the Valkyrie, and the subsequent landing seemed like it took about a month for this Arbites' sensibilities. They had been running around without much in the way of provisions or rest for longer than most guardsmen would be used to. Thankfully Herold was made of stern stuff. The steel of the Imperium and the emperor's strength gave power to his limbs and fed his indomitable reserve, and without a complaint he headed into the Titan complex with the rest of the party. Though he did marvel at the sheer scope and size of the architecture. 

The fact there were no bodies at first was odd indeed, but he felt there would be living or dead guardsmen sooner or later, and he was right. Mostly dead, but the woman they found provided some valuable information. Herold restocked on all of his ammo, preferring to keep the weapons he was familiar with. They had served him well enough so far, the flamer and shotgun would do intense damage in the close quarter's corridors of the facility. 

He kept his weapons loaded but unused as long as the newly chaotic Orks began to rip each other to shreds. Unfortunately and miraculously, they seemed to form some sort of cohesion after a few brutal moments. A stormboy even attempted to attack them, and soon they were having to deal with a green tide. The Arbites stepped forward and hefted his flamer, igniting the air with super-heated liquid, the brilliant flare reflecting off of his visor, showcasing his perpetually grim frown. 

He made sure to scorch and melt whatever Greenskin was not ignited by Angsar. The green and red fire of the two Imperial sent the horde's screaming. Skin melted off the Ork's hides, and their weakened bones snapped under the weight of their Xeno bulk. Herold even fancied he heard pitiful begging screams, something almost unknown to these insane beasts. He allowed himself one of his rare grins, and halted his stream of death once the entire corridor was aflame.  

He switched weapons then, his combat shotgun at the ready to shatter any enemy that had survived.
