The Chapter of the Void was probably the least respected amongst the Chapters of the Word Bearers Legion for it was by far the smallest, with less than 700 Astartes. There was little glory in its history, since it was used as a reserve force that enacted its missions behind the front line. This dishonourable purpose fell to the Void and Chapter Master Tenaebron. The Void's Master did not complain, for he knew that his Chapter's true role was to create and test new weapons and tactics for the rest of the Legion. Lorgar ordered Tenebron to also concern himself with the exploitation of the Word Bearers' psychic resources.Ark of Testimony Chapter - The Ark of Testimony Chapter was commanded by Chapter Master Torquill Eliphas, the "Inheritor".

The Exalted Gate's Chapter badge was a portcullis or gate.Flayed Hand Chapter - The Flayed Hand Chapter's loyalty to Lorgar's cause was undoubted, even if their mental stability was suspect. It seems likely that their zeal was intended to act as an example for those whose commitment the Primarch found to be questionable. Of the 6,000-8,000 of the Flayed Hand deployed at Calth, it is believed, that nearly half of this number fought interspersed with other chapters as well, reinforcing their numbers and in turn their resolve to the mission at hand. The Flayed Hand had enthusiastically embraced the new path of Lorgar and showed particular interest in various occult rites and practices, and from accounts of the surviving Raven Guard and Salamanders veterans of Istvaan V were responsible for a number of atrocities during that conflict. Many among their number volunteered to undergo Erebus' new process for the manufacture of Gal Vorbak warp-tainted warriors, though the process met with mixed results. This Chapter was wiped out during the Underworld War that took place after the end of the formal Battle of Calth.Graven Star Chapter - During the Battle of Calth, the Chapter of the Graven Star is recorded as operating in strength but, as before the Horus Heresy, it was noted that this chapter had made a speciality of boarding actions and gunship-carried assaults. It was known that the Graven Star Chapter had largely retreated from the planet's surface during the final hours of the war, and would go on to further infamy in the Shadow Crusade. The Graven Star Chapter's badge was the Octed or Star of Chaos.Perpetual Spiral Chapter - The Perpetual Spiral Chapter had a proud and illustrious history dating back to the time of their precursors, the Imperial Heralds. Garrisoning worlds brought to compliance by the Legion became the primary function of the Perpetual Spiral, though this was said to have displeased Silak, who saw such a task as lacking in martial honour. Nevertheless, it was a role at which they excelled, and the Chapter was praised by the Primarch Lorgar Aurelian on many occasions. The Chapter was later attached to the 47th Expeditionary Fleet, during which time it led the final assault upon the world designated Forty-Seven Sixteen. It was later after this compliance action that the Primarch took a special interest in Captain Sor Talgron, Lorgar decreed that the captain would lead almost half of the Perpetual Spiral back to the Solar System, ostensibly taking his 34th Company to garrison Terra in the name of the XVIIth Legion. More astute Imperial Remembrancers noted that the move was likely to be politically motivated -- Sor Talgron, already noted for his disregard of the Legion's excessive reverence of the Emperor, was living proof that the Word Bearers had taken to heart the concerns expressed so forcefully at Monarchia. Though these Legionaries presented an officious face to Imperial commanders, in reality they were secretly committing acts of sabotage entrusted to Talgron by Lorgar himself. The Perpetual Spiral Chapter's badge is a flaming spiral.Quillborn - The Quillborn were so named because their traditions emphasized their birth, created in the laboratories and Apothecarions of Colchis. They believed themselves to be written into existence, born as syllables of the Word. A dedicated naval formation, the Quillborn were true marines, fighting ship-to-ship, completely at home battling through the cramped structure of a starship. The Quillborn's Chapter badge was a quill with a drop of blood at its base.Serrated Sun Chapter - The Serrated Sun Chapter's iconography is that of a golden sun, centered on a black lozenge, on a field of maroon. The Serrated Suns Chapter accompanied Lorgar during his Pilgrimage. The Serrated Suns was ultimately lost to the predations of the first Imperial expedition known to ever enter the chaotic eddies of the Eye of Terror and treat with the Ruinous Powers and their daemonic servants directly some forty standard years before the start of the Horus Heresy. The survivors of the Serrated Sun would become the infamous Gal Vorbak, the first known Possessed Chaos Space Marines. The Serrated Sun Chapter's specialty was tactical drop strikes.The Broken Scythe - The Broken Scythe Chapter's iconography is that of a broken black-coloured scythe centered on a maroon coloured circle. This Chapter's specialty was infrastructure reduction.The Inscribed - Nothing is known about this Chapter's particular function or specialty. This Chapter was wiped out during the Underworld War that took place after the end of the formal Battle of Calth. The warriors of the Inscribed were known to decorate their armour with gold runes -- sigils representing various concepts of Chaos on a background of arterial red.The Star of Judgement - The Star of Judgement Chapter's icon was a crimson-coloured gauntlet wielding a mace, centered on a crimson-coloured gardbrace, painted with flames. This Chapter's specialty was scorched earth assaults. The Star of Judgement bore a mantle of dark renown within the Word Bearers, and were deployed only to those war zones where it was deemed that the populace of a world did not deserve the honour of Imperial Compliance. At Istvaan V, the full arsenal of proscribed toxic munitions available to the Star of Judgement was utilised against the unsuspecting Loyalists of the assault's first wave during the Drop Site Massacre.The Tri-Fold Crown - The Tri-Fold Crown's symbol was a cracked bleached skull with flames wreathing its head like a crown. The Tri-Fold Crown Chapter's specialty was attritional warfare.The Unspeaking - Led by the so-called "Crimson Apostle" Zardu Layak, it was said that the Word Bearers of the Unspeaking Chapter were warrior-sages to match any others, stilling their tongues with proud oaths of silence. To honour their masters, the Unspeaking's oath-sworn serfs would ritually mutilate and remove their tongues. This Chapter was wiped out during the Underworld War that took place after the end of the formal Battle of Calth. It was known that the Unspeaking had largely retreated from the planet's surface during the final hours of the war, and would go on to further infamy in the Shadow Crusade.Twisting Rune Chapter - According to certain sources, the Twisting Rune Chapter had been created as a deliberate sink for those of the Legion consumed with hatred of the Ultramarines for the perceived sins of the past. This Chapter was wiped out during the Underworld War that took place after the end of the formal Battle of Calth. The Twisting Rune's Chapter symbol was a twisted Chaotic sigil of eldritch power written in a language of dark, forbidden crafts.
