There has been a cathedral on Baraspine, straight at the terminator line of the tidally locked world, eternally in the twilight. For thousands of years, faithful had prayed there, pilgrims boarded the Chartist vessel to have a chance of glimpsing the famed golden lightning dancing in the spires during the sermon. One day, though, the doors of the cathedral were found closed and gunshots rang through its halls, the clergy throwing themselves at the assailants to prevent them from reaching the holy relic at the sanctum, the head of Saint Laurentius himself. They all died, of course, with the name of the Emperor on their lips.
As young Explorator Toros stepped over the bodies, barrels cooling down, she took pride in seeing something heathens never cared to notice all their lives. All their little cult built upon the singular mistake in its core, they never dared to question the core premises, rejected her diplomatic attempts to make things right and brought doom to both themselves and their flock. She threw away the gilded skull from the sanctum in pure disgust and reached the runes underneath it. For the first time in ten millennia, the cathedral rose up from its knees, faithful fleeing from the apocalyptic tremors of the God-Machine coming back to its senses, its roar ringing with all the pent-up rage of the long slumber.
Young Toros never cared to stop and consider what wretched thing exactly has brought the Titan to its knees. Young Toros knew better than to look for nuggets of truth, the legend of the old saint dying to ensure the containment of the old evil buried under the cathedral. Young Toros knew that she had a chance to revive a fallen Titan and would never allow herself to be distracted by such trivial superstitions. She was the only survivor deemed sufficiently clean. They had to glass a whole peninsula as a precaution. Techzorcism took a little over a century.
She learned her lesson well, never allowing herself to feel smart enough to be invincible, always mindful of dangerous assumptions informing her further actions. As she paced the room, running her fingers along the blasted walls and feeling the breeze from the shattered mosaic windows, she prayed to avoid the misguided faith into the wrong assumptions. She had to start from the very beginning. There has been an assumption that everyone would have made, something obvious and yet not axiomatic, something unchallenged.
"This is not a murder scene.", Secunda stopped in the center of the room, looking at the Omnissiah altar.
"I knew full well that I was not dying here, merely sent to this body. Which the killer, as of today, knew where to find.", she approached the altar, trying and failing to intone an infra-sound prayer with the organic vocal cords. "So, either they had prior knowledge of the location that they decided to act upon today... or they had managed to find it in the matter of weeks, during the general chaos of decapitation."
Her steps locked into a Fibonacci rhythm, straighening her thoughts and allowing her to look at the underlying facts. She turned right, and, step by step, started walking back to the center of the room tracing a Golden Spiral on the floor.
"They used a bolter, not a det-pack - selective killing, relatively minimized collateral to the laboratory. They killed the third and the fourth body of mine, the ones that were never truly intended to be active anyway, contaminated by the sin of gaining consciousness outside of proper protocol. They approached me and then they were notified, by the way of the bolter-fire, that someone else was there." she leaned to the side while making a bend. "They did not sacrifice their puppet to kill me, even though they could have. Fear, as they have been suddenly attacked? It's a puppet, likely piloted by someone organically incapable of feeling fear. Concern, as they did not want to lose an asset or leave evidence? Only someone painfully stupid would not install a dead-man switch detonator somewhere into the body, and I don't like the thought of having been murdered by someone painfully stupid..."
She reached the center again, just as the assumption came. Small rituals like this one have helped her. Stoll loved this one as well. Perhaps, with enough following, this little dance would be mandatory in three centuries. And in five more they would add censers and psychoactive smoke.
"Or they never wanted to kill me in the first place. They figured out someone else in the laboratory, which ensured that I would be released and not fade away in a clone vat. With mission accomplished, they had no reason to hang around and, hence, extracted.", having returned to the center of the room, Secunda massaged her temples. "If they did not want to take my life... they just wanted to take some of my time, some of my memories and some of the cogitator cores."
This question surfaced in her mind again. What the hell was she getting into before getting shot in the head?
She cleared her throat before sending a polite comm to November, double-signing it with Sororitas armour spirit and her own old Explorator cognomen.
"This bio-trash happens to know that the grand late Archmagos Toros has never been a very predictable boss. This bio-trash has reasons to suspect that, being very statistically-minded for logistics purposes, you have managed to figure out some method to the madness, approximating the baseline of the grand late Archmagos Toros behaviour. This bio-trash politely inquires whether the grand late Archmagos Toros had significantly deviated from the expected behaviour in the days preceing the termination of her bodily functions?
P.S This bio-trash politely informs you that Astra Militarum command happens to be looking for a missing package of lasgun chargepacks. As a keeper of order on Isohedron, you shall, doubtlessly, return those. It should be noted, however, that the current Olympia-pattern quotas mention Isohedron obligation to supply the charge-packs themselves - packs being charged at that point is something we do solely out of our commitment to the Imperial cause. As such, no crime would be committed if the shipment arrives in time."
Finally, Secunda has done the thing she was dreading to do all this time. She looked at the chrono-stamp. Memories were something forming her personality - even mindscars of the purged ones dwelled deep inside you, making you who you are. She was herself, even in spite of jumping bodies. She was herself, regardless of how many days, months, years, or decades of memories she irrevocably lost with this transfer. At least she hoped so.
