Traitor Titan

A Traitor Titan

The Legio Argentum is a Traitor Titan Legion of the Dark Mechanicus that repudiated its oaths to the Emperor of Mankind and followed Warmaster Horus into the service of the Ruinous Powers during the Horus Heresy. There is very little information in the Imperial records about this obscure Titan Legion, though it is suspected to have been founded before the Age of the Imperium, during the Age of Strife. The Legio Argentum participated in a number of engagements during the Horus Heresy. It is assumed that the Legio Argentum was either destroyed at the end of the Heresy or was driven towards the Eye of Terror along with the rest of the Forces of Chaos. Its current whereabouts are unknown.

Legion HistoryEdit

Notable CampaignsEdit

  • The Fall of Damantyne (Date Unknown.M31) - During the Great Crusade the Legio Argentum was attached to the 51st Expeditionary Fleet which was also home to the 14th Grand Company of the Iron Warriors Space Marine Legion. After their successful campaign to bring the world of Damantyne into Imperial Compliance, the Iron Warriors built a mighty citadel and left a small detachment of Astartes under the command of the Warsmith Dantioch behind to garrison the planet. The Legio Argentum then left with the rest of the 51st Expeditionary Fleet for parts unknown. During their time away from the planet, the majority of the Iron Warriors fell under the sway of Warmaster Horus and joined his rebellion. The Legio Argentum also threw its support to the cause of the Traitors and became one of the Titan Legions of the Dark Mechanicus. When the 51st Expeditionary Fleet returned to Damatyne for resupply as it began the march of the Traitor Legions towards Terra, Dantioch and his garrison refused to support the Warmaster's cause. The bulk of the expeditionary fleet's forces were then brought to bear upon the recalcitrant citadel, laying siege to its small group of Loyalist defenders for over a standard Terran year. The inevitable conclusion drawing near, an Imperator-class Titan of the Legio Argentum was deployed against the citadel by the Traitors, but was eventually destroyed by the heroic efforts of the defenders. It is not known what other notable engagements the Legio Argentum participated in during the remainder of the Heresy.
