Editing The Justiciars (section)

===The Heresy===

Having his men scattered throughout the Imperium was at once help and hindrance to Uriel's new plans.  The Justiciars loyal to him swiftly went into action sabotaging Imperial infrastructure, disabling astropathic relays, and securing supply depots for the Traitor Legions.  However, some groups of the Thirteenth Legion refused to follow their Primarch into damnation.  These "Iron Angels", as they called themselves, were few in number but particularly adept at slaying the corrupted Librarians in thrall of Chaos.  Aside from dealing with their Loyalist brothers, Uriel's Justiciars were also called on to contain the warriors of the Eyes of the Emperor who had spurned the Council of Ten and rallied to Shakya Vardhana.  If these two subtle Legions did not yet confront one another in great pitched battles, their countless skirmishes over six years of war still added up to a terrible toll in lives.

The Primarch's own Expedition Fleet laid a trap for [[Golgothos]] at Caria, baiting [[the Entombed]] into launching an attack on a position laced with a designer virus that attacked their gene-seed.  Uriel Salazar was greatly moved by this demonstration of the power of the Ruinous Powers and gave himself fully to Tzeentch at this time.  Though this transformation would later see the daemon-Primarch withdraw from the affairs of men, he still led his Legion throughout the remainder of the Heresy and into the cauldron of the Battle of Terra, where they would renew their rivalry with the Eyes of the Emperor.
