Horusian - The First Hour: The ideal of restoring the Emperor to the Imperium in mortal form is at the heart of the Inquisition's formation. In the dark days that followed Horus' invasion of Terra and the Emperor's internment in the Golden Throne in the early years of the 31st Millennium, the empire He had created was reeling in the aftermath of the galactic civil war and the Emperor's Ascension.Four individuals, trusted servants of the Emperor during the building of His galactic empire, gathered together to discuss what was to happen. They were divided in opinion, with two believing that the fledgling Imperium of Man could not survive without the Emperor to directly lead humanity, while the other two were adamant that the Emperor had ascended to a higher plane and that it was folly to interfere with the course of events as they had unfolded.The two Resurrectionists, known only as Promeus and Moriana, left Terra to begin their quest of bringing the Emperor back to life, while the two that remained acted quickly to establish themselves within the newly formed Senatorum Imperialis. Known to the surviving Primarchs as loyal servants, these two began to lay the plans for the formation of an organisation that would combat the efforts of the two dissidents. Thus were the seeds of the Inquisition itself sown.With the backing of the Primarchs, the two first Inquisitors made themselves known to the High Lords of Terra and began to recruit like-minded individuals from amongst the Adepts and warriors on Terra. Their dream of an organisation dedicated to the protection of the Emperor would not be realised in their lifetimes, even extended as they were by arcane technologies, and the Inquisition as it is known in the 41st Millennium did not fully come in to existence until the 32nd Millennium, by which time the Imperium itself and its many institutions were beginning to grow and spread across the galaxy.Promeus and Moriana were not idle during this time, and in the wake of the news of the Emperor's Ascension gathered together a following of their own, particularly amongst those cults and sects that were now appearing on many worlds claiming the deification of the Emperor. At some point Moriana and Promeus split, their goal still the same but Moriana determined to ruthlessly use whatever means necessary to achieve her aim.Fearful that Moriana would unleash unspeakable powers of Chaos to achieve her goal, Promeus created a small army of dedicated followers to combat the menace he believed she posed. These two factions clashed many times until Promeus' disciples prevailed and Moriana disappeared, probably into the Eye of Terror.As the Inquisition grew and its presence was felt further and further from Terra, it came into contact with the Promeans. Several hundred standard years had passed since the fateful first conclave, and even then the Inquisition, ever a confederacy of individuals rather than a single body, was pursuing several different agendas.The original intent, to prevent the reincarnation of the Emperor, had been diluted over the centuries, and when the Promeans were discovered fighting against an ill-specified Chaos threat, they were brought into the fold. Neither the Inquisitors that contacted the sect nor the Promeans themselves were aware of the irony of their cooperation, and thus the first Resurrectionist Inquisition faction was created.
