It has been theorised that the sacrifice of the Thirteenth at Messonia was at the command of the Emperor, for just five years later the Legion would be meet with their Primarch and gain access to the vast manpower reserves of his home world Tiberia.  Fresh genetic material from [[Uriel Salazar]] invigorated the Legion physically, but his moral presence was even more significant.  Salazar's selfless dedication to the Imperium and its peoples, his great humility, and his tremendous self-discipline made him the embodiment of the Thirteenth's principles.  More than just a leader or a father, he was his gene-sons' ideal.  The Primarch's first command was to set aside the name "Iron Angels".  Uriel explained to his men that such a moniker was boastful and unfitting for their mission.  In place of that grand title, he styled the Thirteenth as ''"The humble fellow-soldiers of the Emperor and His justice"'', but they would be more commonly known as '''The Justiciars'''.

Uriel never officially rebased his Legion to Tiberia and always hailed Ancient Terra as the cradle of the Justiciars.  However, in reality, the Thirteenth moved much of their recruiting and training infrastructure to the Primarch's homeworld very early on.  The Eleventh Expedition Fleet officially rejoined the Great Crusade in 820.M30 under Uriel's command, but it would not embark on major campaigns again until 824.M30 when the first classes of Tiberian recruits joined the Legion.  Other Expedition Fleets, at first commanded by Cadigan's veterans, soon followed in the footsteps of the Eleventh and the Justiciars won many splendid victories for the Imperium under their own banner.  Almost as important were the many independent Compliance Groups that went to the aid of other Imperial forces confronted by Sorcerers.  The skills of the Unification Wars had not been forgotten by the Thirteenth Legion, and they hunted witches all across the Milky Way.  Their talents were also used in the fight against psychically-potent Xenos, such as the Eldar.

As the Great Crusade began to reach the fringes of the Astronomican's light, the Justiciar's mission slowly changed.  The Space Marines were too few to hold the vast frontiers of the young Imperium on their own, let alone expand it.  Human warriors of the enormous [[Imperial Army (Hektor Heresy)|Imperial Army]] were committed to the spearheads of the Crusade in ever-increasing numbers.  In addition, many officially compliant worlds harboured treasonous intent.  Uprisings flared up across the Imperium, often led by psykers.  To combat the threats within the Imperium, Uriel began to break up his Expedition Fleets into more Compliance Groups spread thinly throughout the Galaxy.  Although their lack of concentration robbed the Justiciars of the laurels won by other Legion at the end of the Great Crusade, they gladly gave up honour for duty.  Their small bands were indispensable to the merely mortal soldiers of the Imperial Army confronted by the terrors of the Warp.

Yet for every witch-led rebellion that the Justiciars put down, two more sprang up elsewhere.  Uriel Salazar became obsessed with understanding the pattern of these revolts, believing that if he could discover a logic to such events he could better deploy his far-flung forces.  For all the nobility of his purpose, Uriel's great project led him into darkness.  The logic that he worked to understand was the unfathomable intelligence of the Chaos God Tzeentch, the Changer of Ways.  Every new insight twisted the Primarch's great mind towards the paths of Chaos.  When [[Aubrey The Grey]] came to claim the Thirteenth for the Traitors, Uriel willingly knelt before the Arch-Traitor and solemnly pledged his men to Hektor's cause with the words he had once used to affirm his loyalty to the Emperor:

''He wills it''.
