Atellus watched, from the corner of his eye as he kept his head straight forward, as people he assumed to be other members of the retinue enter. First came a priest of of the ecclesiarchy, introducing himself as a Confessor named Ignacius Christus. An older man than Atellus, looking somewhat grizzled and dressed in the robes that one would expect a man of the faith to be wearing. He was in the middle of idly guessing Ignacius' true age when a subtle sense of 'wrongness' washed over him, forcing Atellus to stand straighter as he tried to figure out its source. Whatever it was, it was different than the same feeling that Atellus picked off psykers.

As a voidborn, Atellus spent his entire childhood, hell, nearly all of his life, aboard a spacefaring vessel, and a decent amount of that time aboard was spent in warp transit. Perhaps it was because of this that Atellus had always found himself a little more sensitive to the more subtle aspects of the warp, compared to most planetbound imperial citizens, and while he was by no means a psyker, he had always found that he could pick up on certain 'feelings' and 'auras' such that seemed to follow most psykers around. And as such, Atellus felt it rather distinctly when the feeling of wrongness from earlier seemed to smother the room, quashing the psychic presence that was present in the room earlier, and seemingly foretelling the arrival of another member of the Inquisition, an Interrogator, Atellus would learn a few moments later. The sudden shock of this feeling actually forced Atellus' head to snap towards the woman, staring at her as he tried to comprehend what had just happened.

Next would come a tech-priest, introducing himself as a Magos of all things, followed by a member of the Imperial Guard, although the medical jacket the man wore over his armor either hinted at some form of eccentricity or a medical background of some kind. The last two to enter were more members of the ecclesiarchy, rather puritanical hardliners if their manner of speech was any measure of character, and their gear gave off a few rather heavy hints of it too. Atellus then started as an assassin dropped down from above, taking place besides the Inquisitor, obviously ready for hostile actions, with her hands on her weapons like that, and Atellus bristled slightly, getting more and more nervous at the situation he found himself in. He had stuck himself into a hell of a bad place to be, it seemed, stuck into a group with a Magos, an assassin, and two sadistic looking women who would probably be willing to tear him to shreds at the slightest sign of heresy, if the Interrogator and the Inquisitor weren't willing to already. The others, Atellus could handle well enough, seeming like normal enough people, but these people... These were people in high places, capable of killing him with ease and likely capable of doing it without even getting a slap on the wrist. He found himself questioning if he was needed here in the first place.

He did his best to turn his attention to the Inquisitor as introductions were done and the briefing was stared, Atellus visibly trying to relax as he lowered his rifle to point at the floor, though he was still rather stiff due to his nervousness. He learned that they were after a Navigator, a powerful psyker to be sure. Atellus had done some time guarding the hallways leading up to the Navigator's station, as well as their rooms, both of which were rather unpopular amongst the other armsmen, and so he knew a little bit about them. The most memorable thing about them he had learned was that they were capable of seeing the Astronomican, the literal Light of the Emperor, his presence within the warp. He wondered how someone capable of seeing such a thing was capable of turning to Chaos themselves...

He shook his head of such thoughts, turning back to look at the Inquisitor as he asked for questions. "If you'd pardon my intrusion, Inquisitor... What brings Astradas here of all places? Is he simply following the warband around? And if so, why? If he has knowledge of such an artifact, surely the man would be chasing it down."
