{{Main|Imperial Reformation (Hektor Heresy)}}

Following the crisis of the Heresy, [[Gaspard Lumey]] leads the Imperium for a decade as the '''First Lord''' of the High Lords of Terra.  His tenure is marked by military consolidation and the formation of Segmentum Commands under his remaining brothers, [[Arelex Orannis]] (Lord Pacificus), [[Brennus]] (Lord Obscurus), [[Onyx the Indestructible]] (Lord Ultima), and [[Shakya Vardhana]] (Lord Tempestus).  In 031.M31, Lumey appointed Arelex Orannis as his successor and took up the post of Lord Pacificus.  During the transition period the two Primarchs presided over the sundering of the Legiones Astartes and the foundation of the Imperial Navy, Imperial Guard, and Space Marine Chapters.

Orannis's rule as First Lord was characterised by a remarkable period of rebuilding, particularly in the war-ravaged Sol system.  Unlike Lumey, who had avoided humanity's cradle and ruled more often than not from the command centre of his flagship, Orannis brought the seat of Imperial government back to Terra.  The sire of the War Scribes oversaw the construction of whole hives dedicated to the administration of the Imperium.  He also smoothed the constant religious struggles between Mars and her daughter worlds, ensuring that the Red Planet received aid from the younger Forge Worlds so that it, too, could be restored to something of its pre-war glory.

Following the regimes of the Primarchs, control of the Imperial administration was passed over to the High Lords of Terra.  For two centuries, these mortal men and women gradually took up the task of running the Imperium while the sons of the Emperor defended the frontiers and occasionally travelled to Sol to impart their wisdom to the council.  But by the third century of M31, the Loyalist Primarchs had all departed the scene of history and the Imperium of Mankind would finally be ruled by mortals.
