The Legio Adamantus is a Loyalist Titan Legion of the Collegia Titanica.

Legion History

This Legion's existence has been confirmed by several battle-honours that all pre-date the dark times of the Horus Heresy, including the original Imperial Compliance campaign for the world of Istvaan III, where according to records drawn from the Raven Guard Legion, the Legio Adamantus fought with their brethren of the Legio Victorum to first bring Istvaan III into the Imperial fold during the Great Crusade.

As no further mention has been made of the Legion since the earliest 31st Millennium, it is unknown if this Titan Legion still exists in the present 41st Millennium or even where its true allegiance lay.

Notable Campaigns

  • Istvaan III Compliance Campaign (994.M30) - Fighting alongside the 27th Expeditionary Fleet under Primarch Corvus Corax of the XIXth Legion, the Titans of the Legio Adamantus participated in the initial Istvaan III Compliance campaign. The military forces of the indigenous Istvaanians were highly sophisticated and disciplined, requiring even the mighty Raven Guard to ask for Titan-support. Alongside their brothers of the Legio Victorum, the Titans of the Legio Adamantus crushed enemy resistance into oblivion and were thus rewarded by a place of honour during the triumph of the Redarth Valley.
