"Hereticus." I said, my tone neutral. Emmaline could see my eyes moving as thoughts whirred in my head. She had done some fine detective work, but something did not feel right. It felt as if the answer were right in front of me, but I needed to parse the facts. I glared at Lazarus for a brief moment, until Emmaline drew my eyes.

"Problem?" Emmaline asked, raising her brow. She wore a shimmering dress that suited her. I merely wore my usual fatigues and newly stitched jacket, now finally able to move about without half my torso bandaged up and crushing my ribs. I snapped my fingers for Lazarus to approach with his data slate, my hand out-held to retrieve it. Once in my hands I thumbed through the data. 

"On Havenos, he wore Malleus Power Armor. You not only need to be in my ordo, but one of the more esteemed members to even have the access to don such a blessed suit. Being of the Ordo Hereticus makes little sense," I explained. 

"Then he just found a Malleus Inquisitor and killed them?" Clara suggested. She seemed more able to think back to that day. Earlier the mere mention brought shudders to her, the inhuman dimensions of the eternal city having done its damage on her sense of self for some weeks. 

"That's highly unlikely for many reasons, and for an unordained, veritably impossible. Such a suit could devour the man within if they were found unworthy. No, no this makes me believe that he was not wearing what I believe he was wearing, or the information is wrong. Perhaps both." I remarked, a galactic map surging onto my screen, fingers sliding the expanse of space down as I veered the tablet's screen northward. "And you are wrong, Lazarus." 

"Pardon?" Lazarus asked, binary spewing forth a scant second after the statement. It was rare to see the Tech Priest rocked back on his heels. Selencia perked up. 

"You are wrong." I said simply, glancing at him. "I haven't known you to be wrong about an empirical fact since I've met you. The Orphidian subsector is quite close to Avignor. It's all within the Scarsus Sector of Segmentum Obscurus. And Emmaline's information of his origins is quite odd. Both Angevin and Ophidian are the names of relatively recent crusades in Imperial history." 

"The Ophidian sub was named after the crusade," Lazarus noted, though whether to try and regain a bit of dignity or to see if he was capable of answering correctly, I did not know. He was impossible to read to most humans, but I could see he was disturbed at his own failure at making a single incorrect statement. Lucius Raj watched the exchange with interest from the back, his super human eyes more accustomed to seeing small micro-twitches that betrayed emotion. 

"Correct. In fact it was one of the most successful crusades in the history of the Imperium. It was as if the forces of Chaos had fled after the fighting had barely started, hailed as a miracle and a sign of the Emperor's favor. The Angevin Crusade had a similar record, and is known in my Ordos as being one of the few crusades Ordo Malleus has openly aided in. I do not know the specifics of Ordo Hereticus and their conclaves, but I find it difficult to believe they would have one named after the Angevin crusade." 

"What exactly are you suggesting, Hadrian?" Emmaline asked, placing a hand on her hip. She seemed slightly put off at my interruption, and while I did not take any pleasure from it, she looked fetching when she was frustrated. "That my information is wrong?" 

"Not necessarily." I clarified, handing the dataslate back to Lazarus. "He may very well be Teritus Vorn of the Ordo Hereticus. However, he is not the true enemy. The Ordo Malleus does not go after men, but the very daemons of the warp, and when they are concerned, you trust nothing. This cabal has infiltrated every level of not only a Hive World, but now the Ecclesiarchy and the Inquisition? And he has developed away to strip millions of imperial citizens of their free will all on his own? This man, Teritus Vorn, is just a cog in a greater wheel. There are only two explanations. Either not every piece of information we received is truthful, or there is a much more sinister and devious aspect to their methods. One that might explain your information and Lazarus' misstep." 

"[i]Mors Logicae[/i]?" Lazarus responded, looking up from the dataslate I have granted him. On the screen, he had been granted access to the entire history of the phenomena. He could absorb the information quicker than I could explain, but I deigned to do so for the congregation listening. Urien watched in fascination and both Selencia and Emmaline glanced at one another before looking back at my position. 

"Discovered by Inquisitor Jaq Draco in the late 38th millennium, it is a taint of psychic origins, a ward. Some classify it as a 'disease of truth.' The [i]Mors Logicae[/i] activates when one approaches a certain subject intellectually, granting false leads and giving the researcher an inherently wrong mental synapse of the topic in question. Fortunately, Jaq Draco was able to dismantle it by learning two simple weaknesses. Firstly, the [i]Mors Logicae[/i] can only work when one does not consider its existence as the cause. Secondly, while it can alter ones perception of facts, it cannot alter facts themselves. It is a taste of the warp, but not chaos made manifest. Therefore, what we have seen is indeed fact, and now that we have acknowledged it is a very real possibility this alleged Teritus Vorn is utilizing it, then we cannot be fooled again unless it is by others who have been fooled." 

"That means all information we gather will be false, though," Clara surmised. 

"Not exactly. It only works on someone who is looking into a specific subject, as I said. For instance, this Teritus Vorn can land on Avignor, tell everyone he is Teritus Vorn, and he is an inquisitor, and he will have to convince them on his own. If someone there was to ask him his business on the planet specifically, he could tell them any lie he wished. However, if one were suspicious of his motives and deigned to pick them apart, everything they would hear or surmise regarding him would be scrambled by the neurons in their mind or the mind of others. Unless, of course, they suspected the use of [i]Mors Logicae[/i]. As we now do. His whereabouts or mundane activities would not be unknowable." 

Lazarus snapped the dataslate shut, and with a string of binary that sounded like a long sigh, he approached me and, to my surprise, patted me on the shoulder. I had been about to explain how the Ordo Angevin and Ophidian claim was likely based upon the [i]Mors Logicae[/i] choosing the two most illustrious words in the Scarsis sector to garner trust by local inhabitants, but Lazarus spoke first.

"Kronus would be proud," He whispered. I gave a smile.
