Changes

Originally, during the days of the [[Great Crusade]], the Iron Warriors were known for their stoic, cold, and dour nature. However , as the Crusade continued and their feats were not acknowledged, this demeanor demeanour turned to resentment, bitterness, and an ease inclination to take offenseoffence.{{Fn|85b}} Any sign of compassion or failure was seen as a weakness and would result in immediate shame or punishment, as was the case with the likes of [[Barabas Dantioch]] following the [[Sak'trada Deeps Campaign]].{{Fn|25d}}

Iron Warriors came to harbor harbour huge pent up rage, particularly against the [[Imperial Fists]] and their Primarch [[Rogal Dorn]] to which whom they were often compared against. This helped them to be corrupted to precipitated their corruption by Chaos during the ensuing [[Horus Heresy]], but the Iron Warriors maintain absolute loyalty to Perturabo before any individual [[God of Chaos]]. The Iron Warriors revere their Daemon Primarch, whom they believe saved them from being sacrificed by the Emperor.{{Fn|85b}}

Outside of battle, the Iron Warriors would always hone their craft for warfare. They maintained a number of warrior societies to this end, such as the [[Lyssatra]], [[Apolakron]], [[Dodekatheon]], and [[Kheledakos]].{{Fn|20b}} Iron Warriors would practice battle tactics and simulate battles by engaging in mock battles with one another using tabletop miniatures. More than mere games, such simulations were taken with dire seriousness by Iron Warriors legionnaires.{{Fn|25e}}

Ten thousand years later, the Iron Warriors still maintain the same pride, resentment, ferocity, and icy methodology, especially against the Imperial Fists or any of their successor Chapters. Their anger often manifests into cruelty, and they will gladly enslave and exterminate the citizens of the Imperium in massive numbers.{{Fn|9c}} The Legion as a whole cares little for their own, and even Perturabo was known to callously destroy ships of his own fleet if they were in the path of his flagship ''[[Iron Blood]]'',{{Fn|86}} and was know to strike down his own sons as a way to vent anger.{{Fn|13}} This attitude extends to the Iron Warriors themselves, and they are known to violently settle old feuds and grudges with one another under the cover of battle.{{Fn|86}}
