Kyril Sindermann was the Primary Iterator of the 63rd Expeditionary Fleet during the latter days of the Great Crusade. He was a gifted speaker and master of rhetoric, and a staunch beliver in the secular society and ideals that the Emperor had imposed on the Imperium.
Sindermann had been the star pupil of the iterator Evander Tobias, who had trained the first iterators and had been intended to serve as Primary Iterator for Warmaster Horus's fleet. When his voice was crippled by cancer of the larynx, Tobias recommended Sindermann to go in his place.
Sindermann shared a strong bond with Luna Wolves Captain Garviel Loken, whom he had long mentored in the history of ancient Terra, and would often give the young Astartes warrior great tomes to read as part of his education in the Imperial Truth.[1a]
During the pacification of Sixty-Three-Nineteen, Sindermann and several remembrancers from the fleet were attacked by a foul daemon of Chaos which had possessed a Luna Wolves officer named Xavyer Jubal.[1b] This traumatic event led him to question his secular beliefs, and also to question why the Emperor had been so adamant in his refusal to acknowledge such entities. For many months, Sindermann sought answers in the vast libraries of the Vengeful Spirit.[1c]
Speaking with Euphrati Keeler, another witness to the possession of Jubal, Sindermann attempted to use fragments of text and images taken by the remembrancers to decode sections of the infamous Book of Lorgar. While reading aloud from the scripture, he became entranced and inadvertently summoned a fiery daemon which set about destroying the library archives. He was saved by the pious actions of Keeler, who had long held faith in the supposed divine influence of the Emperor, and exorcised the creature before falling into a coma.
This tested Sindermann's belief in the Imperial Truth even further, until he could no longer believe in it at all. He had seen too much proof that the old religions and sects had in fact been based in matters over which the average being had no control, and therefore they relied on higher beings to protect them. So did Kyril Sindermann accept the Emperor as his saviour, rather than his ruler.[Needs Citation]
During the battle for Isstvan III, Sindermann escaped from the Vengeful Spirit, along with Keeler and Mersadie Oliton, with the aid of Captain Iacton Qruze. They fled to the frigate Eisenstein, taken by Death Guard loyalists led by Nathaniel Garro,, and escaped the Istvaan system.
