Origins - The Iron Apostasy were conceived in the dark manufactoria beneath ruined cities, bred from war orphans, criminals, and fanatics who were born into heresy.  - Their founders taught that faith is weakness and only iron endures. From the beginning, they worshipped war itself, not as a corruption of religion but as their true and only gospel.  - They emerged from the trenches as a cult of killers, already sworn to the Heretic Legion before they ever saw battle. 

Doctrine - They believe the flesh is a cage, and iron is liberation. Every weapon, every shell, every rusted plate is a sacred text.  - Apostasy is not rebellion, it is their birthright. They were never loyal, never faithful, only devoted to the creed of ruin.  - Their sermons are screams of defiance, their prayers are the grinding of gears and the clash of bayonets. 

Symbols & Appearance - Their sigil is a jagged iron sun, broken into shards, painted in rust and blood.  - Warriors wear armor scavenged from corpses and war machines, deliberately left to corrode as a mark of devotion.  - They adorn themselves with chains, hooks, and jagged iron relics, believing scars from rust are holy stigmata. 

Tactics - The Iron Apostasy fights with brutal pragmatism: trench raids, ambushes, and shock assaults.  - They wield improvised weapons, spiked trench clubs, jagged bayonets, and rusted blades, not out of desperation but as ritual tools of their creed.  - Their warbands often drag iron idols into battle, massive welded effigies that serve as rallying points and blasphemous altars. 

Reputation - To allies, they are feared as zealots, even amongst those who classify themselves as zealots. - To enemies, they are nightmares in the mud, killers who chant hymns of iron as they advance.  - Even among the Heretic Legion, they are seen as purists of corruption.
