The latest Horus Heresy lore drop puts the Word Bearers back in focus. They are framed, quite rightly, as the original traitors.
However, the real hook is how their fall started with devotion, not simple ambition. So, this spotlight lands as a reminder that the XVII Legion broke the Imperium from the inside.
The First Great Fall of the Heresy
Originally, the XVII Legion were the Imperial Heralds, charged with spreading the Imperial Truth and crushing false faiths. Then Lorgar was found, and that same zeal hardened into worship of the Emperor himself. However, once the Emperor rebuked them, their faith did not die. Instead, it curdled. The big beats here are Monarchia’s destruction, the Legion’s bitter humiliation, and the pilgrimage that led them toward powers willing to accept devotion. That road, of course, helped create the Gal Vorbak and set the tone for everything rotten that followed. It is classic Word Bearers stuff, because nobody in the setting turns wounded belief into apocalypse quite like these lunatics.
