I spat a curse as my rounds ricocheted off his blessed armor, wondering why in the emperor's wisdom this chaos filth had been able to attain such a sacred item. I managed to get off four shots in the time it would take an average gunman two, but still Vorn managed to get away. I was thankfully Emmaline was alive, at least. When he had flashed us with whatever device he had discharged, I had foolishly encouraged Emmaline to pursue. I was so used to having more team-members, I had always signed my lover's death warrant. I caught up in short order, sliding over to my aide and embracing her. 

"Are you hurt?" I began to ask, but she sneezed wildly, her shoulderguard striking me in the upper lip. Blood burst from my nose and gums, flecking my lips. I was stunned for a brief moment and Emmaline's eyes widened in shock and guilt. 'Had-' She began, but I shook my head. "Don't worry on it now. I had Gwydyn fetch the car. But we have to hurry." 

"He's gone, we need to make it back to Fulstes," She lamented, but with my pride she did not seem perturbed by nearly being killed a minute prior. 

"No, we can still catch him." I remarked, getting to my feet. She blinked curiously, lifting herself up as well. I reloaded my autopistol with a swift execution and kept it unholstered. "That was a personal teleporter," I said with distaste. Despite my liberal viewpoint on psykers and metahumans, I shared my ordo's disdain for certain practices and technologies that were theorized to bring one closer to the warp. Teleporters were one of those loathsome feats of engineering, but as all things heretical, Hadrian had studied them. "He could only travel one hundred meters with it, and that's without taking warp disruption and landscape into account."  

"Then let's go," She said, hefting her bolter. 

"Aye sister," I said, granting myself a small smile. She returned it a thousand fold, and we moved as one, past the long gallery of the now-ruined mosaics and into an antechamber furnished with busts of now long dead cardinals. Had I time to pause I would have almost thought it a form of righteous masturbation, as the bust of the recently dead Cardinal was at the very center of the room, all eyes gazing in his direction, his arms outspread to accept all praise to his person. We slid past his holiness and entered the tail end of the compound, hurrying down a large stairway, pilgrims screaming in surprise at our brandished weapons. 

I believed I caught a flicker of movement turning the corner out of the archway at the far end of the chamber. Emmaline saw it too, springing off the last six steps, hitting the ground without pause as she raced ahead. I was not going to be left behind, making my own jump and landing in a roll, sprinting just behind her. As we ran under the arch, I holstered my gun and grabbed my power sword, getting the sudden thought that it might be the better weapon if we caught up to him once again.
