The Legio Magna (Flaming Skulls) 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 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 Magna's homeworld was located in the Ultima Segmentum, where they hailed from the seventh planet of the Estaban System, the Forge World of Estaban VII. It is assumed that it 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.

Notable CampaignsEdit

  • Schism of Mars (Unknown Date.M31) - Later Imperial histories record that the first blow of the Martian civil war unleashed during the Horus Heresy that was known as the Schism of Mars was struck against Magos Mattias Kefra, whose forge in the Sinus Sabaeus region of the Red Planet was housed within the Madler Crater. Titans of the Legio Magna marched from the southern Noachis region and within minutes had smashed down the gates of his forge city. Howling engines daubed in red, orange, yellow and black and decorated with flaming horned skull devices, ran amok within the high walls of the crater, crushing everything living beneath them and destroying thousands of years of accumulated wisdom in a fury of fire. Vast libraries burned and weapon shops that served the Solar Guard Imperial Army regiment were reduced to molten slag as the indiscriminate slaughter continued long into the night.
  • Battle of Terra (Unknown Date.M31) - The Legio Magna took part in numerous engagements during the dark days of the Horus Heresy, but its most notable action occurred when they participated in the Battle of Terra and the Siege of the Imperial Palace alongside the other Traitor Titan Legions.

Canon ConflictEdit

The Traitor Flaming Skulls Legion are revealed in Imperial Armour Volume One to be the Legio Magna. The Legio Magna, however, appears in several other sources as fighting on the side of the Imperium -- they are mentioned to have taken part in the Angevin Crusade, defended the world of Orask from a Tyranid splinter fleet, and, most recently, participated in the Third War for Armageddon. It is unknown if part of this Legion remained loyal during the Horus Heresy and has survived into the 41st Millenium maintaining its old name, or whether this simply is a mistake on the part of Games Workshop.
