Last to enter and speak would be the Confessor. Horacio had the short interim of peace quite boring. He was privy to all sorts of of hypocrisy and gluttony, even if he didn't take part in it. He saw many an obese Priest or Imperial official in hedonistic acts, which frankly disgusted him. Despite his girth the Confessor ate like a bird and his only real indulgence was recaf so strong one would doubt if an Astartes could stomach it. 

He prayed much in the time that was spent in between, but he didn't do it on his knees on a Chapel. No, that was for either those who had faith as strong as his, yet not his status or those who had his status and wanted to make a public show of their piety before quietly inviting whores through the back door of their office. Horacio thought of the old story of Arius and the farmer he learned on some shrine world he couldn't quite be arsed to remember at the moment. There once was a great Priest named Arius, feared by  heretics and xenos alike whilst respected and adored by Imperials for his knowledge of Imperial Catechisms. The Priest believed himself to be the most pious man alive, until one night he saw an apparition, something the Emperor himself sent to speak to the man. It told him that he was pious indeed, but there were those more pious than him, one of few such people upon the highest peak of the world he was on named simply Holdten. Arius wasn't sure if he should be outraged or humbled, and decided upon both until he went to the mountain's peak. There he met a humble man, a poor miner with the oldest and rusty machinery to do the Emperor's work. He asked Holdten what was the secret of his piety, of his prayer that made him even more pious in the eyes of the God Emperor of man. He was confused, and bowed before Arius. He replied that he knew of no prayers for he was illiterate, and unlearned. Whenever he had time to go to the Chapels upon the planet he did the same thing as when he prayed at home. The man simply spoke every letter, word, and even mark of punctuation he knew, and hoped that the Emperor would assemble these words for him into his hopes for mankind, and that for him he would simply be given another day in service of his God. Arius at this point realized that from the heart and soul, not from pathetic and purely material things like the brain and memory came one's divinity, devotion and piety. 

Horacio rather liked the story. It kept him from arrogance, and it put those people who needed a lesson in humility right in their place. If anything, the story also taught one to be practical. One's prayers to the Emperor were for naught if he didn't serve the God after that. The Emperor protected mankind, but mankind has to protect him. 

All of this raced through the Holy man's mind as he awoke that morning, knowing somehow that this day would be different. He looked through a few reports he was too tired to read the night prior that he left beside his rather tiny and cramped quarters. It was on a scroll that had a tendency to go back to it's rolled up state, so he had to place his shotgun on one end and his pistol on the other. He was about to pick up the scroll when he received communication via his vox-bead to check his dataslate. Annoyed, he started to make his recaf and read the small tablet, brightening up at the realization that he had a choice on whether or not to stay upon the world. Adventure called to the man,  as chances to spread the word rather than keep it in one place was exactly what he was good at. The Confessor banged his power maul on the door to his quarters which was promptly opened by a scribe who tried to hide a cough at the intense smell of Horacio's recaf. "Inform all pertinent that I shall be leaving the world. This new business has interested me." 

With that, the Priest washed himself off as best as he could in his time constraints, put on all parts of his attire and gathered up his other personal items. Satisfied, Horacio went off. As he saw the Sisters he had so recently served the Emperor with, he nodded respectfully and quietly said "Hullo." He did not have any input beyond that, yet. He only knew that some potentially nasty business was ahead of them, for he had not read the whole of his dataslate - he was still busy sipping the last of his vile recaf.
