Foundation Date

Foundation Date (d100)
01	Ancient Origins: A most ancient and venerable house. This noble family can trace it's origins to pre-Imperium nobility from the Dark Age of Technology or further, going far back to the Age of Terra. Whether true or not, the fact that their house predates the Imperium means that this family is proud of it's origins, and may hold considerable power within the Imperium.
02-04	Age of Strife: This house was founded during the Age of Strife, and predates the Imperium by many millennia. Whether they fought against the Imperium and brokered an agreement, or worked with them the moment they were founded, this House boasts a rich and illustrious history. They may wield considerable influence within the Imperial war machine or bureaucracy.
05-07	Unification Wars: Since its inception, this House stood as a peer of the Imperium. Whether its founder was a Warlord or a dedicated servant of the Emperor from the beginning, this house played an integral role in laying the foundations of the Imperium of Man.
08-10	Great Crusade/Horus Heresy: Originating either on a newly conquered world or from the ranks of Imperial Army regiments embroiled in conflicts for or against the Emperor, this noble House emerged within the vast shadow of the Imperium. With a history possibly marked by participation in the pivotal battles of the Great Crusade and/or the horrors of the Horus Heresy, this family traces its roots to the times when the Emperor's radiance graced the heavens — or to the bleakest hours when traitorous legions plunged the Imperium into chaos.
