The Legio Arconis ("Iron Kings") was a Loyalist Titan Legion of the Collegia Titanica.

This Titan Legion was based upon the Forge World of Sareme.

However, with the formation of the Great Rift at the dawn of the Era Indomitus, Sareme was enveloped within the growing Warp Storms and fell to Chaos.

Legion History

It is known that the Legion has fought for their homeworld since the Age of Strife.

During the Horus Heresy, the Iron Kings Titan Legion remained loyal and fought on behalf of the Imperium. They continued to faithfully serve the Emperor after the Heresy and fought on behalf of the Imperium for ten millennia.

Unfortunately, their long and glorious history has come to a tragic end.

With the destruction of Fortress World of Cadia and the formation of the galaxy-wide tear in reality known as the Cicatrix Maledictum, the Iron Kings' homeworld was enveloped by the Warp and many of its Mechanicus Tech-priests were corrupted by the Ruinous Powers and became Hereteks.

Now adherents of the Dark Mechanicum, the Traitors overwhelmed the few remaining Loyalist remnants of the Forge World. The planet likely fell to the service of Chaos.

Despite their valiant defence, the Iron Kings were likely destroyed with their Loyalist Mechanicus brethren, though their fate remains unknown.
