The Iron Way began with the legends of the Iron Scrolls, a massive library of text stored within the great halls of the Battlefield, the warring place for the glorious dead where their souls defend the plane. These scrolls contain the legends of great heroes and their famed exploits. Everyone who achieved martial glory finds themselves mentioned within the Iron Scrolls. Adherents of the Iron Way seek to have their legends written down for eternity and so they seek out causes and challenges in order to prove themselves and their skills.
Followers of the Iron Way set out to prove themselves always, they never turn down a challenge and will gladly rush into battle, what holds them together as a cohesive order is that an adherent of the Iron Way will always heed the call of another, coming to their aid without thought of reward. Adherents of the Iron Way will also target other followers to the exclusion of everything else should they meet on opposing sides of the battlefield.
There is no formal way to join the Iron Way, you are simply required to be strong and to wish to follow the Way’s tenets. However, if one who says they follow the Way abandons it, they may face violent retribution from “true” followers, who despise such betrayal.
