Perpetual Spiral

The Perpeptual Spiral was a Chapter of the XVII Legion of the Adeptus Astartes, originally the Imperial Heralds, later the Word Bearers. It distinguished itself early in the Great Crusade under the command of Chapter Master Balas Silak, bringing the five worlds of Thoth into compliance and defending them from the neighbouring Xenos-influenced Anhur System. After these early campaigns, garrisoning of worlds brought into compliance became the Perpeptual Spiral's primary duty, a status that was thought to rankle Silak and his dreams of greater martial duties. The Chapter was present at Monarchia when the Emperor admonished the Legion for its deification of him. Subsequently, the Chapter joined the 47th Expedition - Lorgar's own expedition fleet - and led the compliance action of Forty-Seven Sixteen. There a Centurion of the company, the Captain of the 34th Company, Sor Talgron, earned the Primarch's favour. This caused resentment in Silak and Talgron was subsequently sent by Lorgar to garrison Terra with almost half the compliment of the Perpeptual Spiral. These soldiers presented an officious face to Imperial commanders, but in secret committed acts of sabotage entrusted to Talgron by Lorgar himself. The remainder of the Chapter stationed with the 47th itself perished during the Istvaan V betrayal, where they were present in the first wave that surprised the retreating allies of the "loyal" legions, the Salamanders, the Raven Guard and the Iron Hands. Left in command of the remainder of the Perpeptual Spiral, Talgron led them in the succeeding Horus Heresy.
