Ordo Chronos

Even amongst the ranks of the most learned of Ordo Calixis Inquisitors, few have ever heard the
name of the Ordo Chronos, and still fewer have any inkling as to its mission. It is thought that the Ordo
came into being as a result of the study of the effects of warp travel and the passage of time. It is common
knowledge amongst void farers that occasionally a vessel arrives at its destination much, much later than its
Navigator intended, the crew experiencing the passage of mere months for example, while in the material plane
many centuries passed. Such events are the subject of many dreadful tales, but are accepted as one of the risks
of warp travel. Far less common, however, are those occasions when a vessel has become embroiled in a warp
phenomena that has resulted in it being expelled from warp space at a point in time before it actually set out.
Though extremely rare, this is the subject of nightmare for superstitious void-farers the Imperium over.
The Ordo Chronos, so it is believed, was established in the Jericho Reach in order to combat any
temporal anomalies that might arise from these, and similar events. Its members became concerned that
travelers appearing in their past might somehow alter the proper flow of events, potentially interfering with the
fate of Mankind and the intentions of the Emperor. Over several centuries, the Ordo Chronus investigated
instances thought to be related to all manner of temporal phenomena, their work expanding beyond the original
warp-related events to others, perhaps of a deliberate nature.
And then, the Ordo Chronos simply disappeared. None know how many members the Ordo had, but it
appears that in a single moment, every Inquisitor linked to it vanished or went into hiding. Whispered tales
have appeared over the centuries, some hinting at the involvement of renegade factions within the Adeptus
Mechanicus and pursuit of certain technologies long forbidden to that ancient brotherhood. How and why the
Ordo Chronos vanished, and if its members may one-day return, remain the subject of legend amongst those
few who know they ever existed. Some, it is said, await that day, eternally vigilant against the doom such an
event might presage for the future of Humanity itself.
