Word Bearers
The Word Bearers, originally known as the Imperial Heralds and the Iconoclasts, is the XVII Legion of the original twenty Space Marine Legions. They were the first of the nine Legions which betrayed the Emperor, pledging their allegiance to their Primarch Lorgar and the dark gods. Known for their extreme religious fervor, the Word Bearers are some of the most fanatical Space Marine Legions. When it became clear that humanity could not be enlightened without bloodshed whilst it remained shackled to the lies of the Emperor, Lorgar and Erebus helped orchestrate the corruption of Horus himself, initiating the Horus Heresy.
