Legio Tempestus

The Legio Tempestus is one of the oldest and most esteemed Loyalist Titan Legions of the Collegia Titanica, one of the military arms of the Adeptus Mechanicus. There is very little information in Imperial records of when they were founded, though it is known that they were founded before the Age of the Imperium sometime during the Age of Strife. The home of the Legio Tempestus was none other than Mars in the Segmentum Solar - centre of the Cult Mechanicus and seat of its ruling Fabricator General. Their fortress-mountain was located at Acraeus Mons near the end of the Ascraeus Chasmata. They shared this rugged and inhospitable region of Mars with their rivals, the Legio Mortis, who were located at the other end of these ashen wastelands at their fortress at Pavonis Mons.

Legio History
During the 31st Millennium the climate on Mars was one of discontent. There were tense relations between the various Techno-Magi with sporadic outbreaks of espionage and violence being committed against the various forges that represented the primary sociopolitical units of Mars. There were even unconfirmed suspicions that the Titan Legions had already secretly chosen sides in case of a potential conflict. Senior Princeps Indias Cavaleria 'The Stormlord' of the Legio Tempestus sought to his Legio free from the insidious poison of politicking. He believed that the Titan Legions should remain true to their warrior ideals and not be instruments of political will, save that of the Imperium itself. During the Great Crusade the bulk of the Legio was on crusade with Primarch Roboute Guilliman's Ultramarines Legion.

Horus Heresy
When the Schism of Mars occurred during the opening days of the Horus Heresy the Legio Tempestus sallied forth in support of Magma City, a loyalist forge that stood defiant of the newly imposed order of the corrupt Fabricator General Kelbor-Hal and his Dark Mechanicus co-conspirators. Facing the gravest crisis in it long and glorious history, Senior Princeps Cavalerio felt that warriors of honour and courage should not stand idly by in such times, they should act. The Legio Tempestus stood firm in the face of aggression in the defence of their allies, though they knew they would find their inevitable doom at the hands of their hated rivals of the Legio Mortis. The Legio Tempestus were overwhelmed by the superior numbers firepower of their rivals. Despite the odds, 'The Stormlord' valiantly led his Legio in the destruction of the 'Deaths Heads' lesser war machines, only to face their destruction at the hands of the Imperator-class Titan Aquila Ignis. The Legio Tempestus would go on to fight throughout the darkest days of the Horus Heresy, participating in numerous engagements.

Notable Campaigns

 * Epsiloid Binary Cluster Campaign (Unknown.M31) - A campaign conducted by the Legio Tempestus on behalf of the Adeptus Mechanicus during the Great Crusade. The Legio suffered the loss of 6 engines and many wounded, including the already battle-scarred Victoris Magna, the towering war machine of 'The Stormlord'.
 * Schism of Mars (ca. 205.M31) - Legio Tempestus supported the Loyalist Mechanicum during the opening days of the Horus Heresy, defying the traitorous Fabricator General Kelbor-Hal and his Dark Mechanicum. They fought a major engagement at the loyalist forge known as Magma City against their bitter rivals of the Legio Mortis. Though they managed to destroy all of their lesser war machines, these detachment of Storm Lords Titans were wiped out by the remaining enemy Imperator-class Titan.
 * Defence of Orestes (779.M41) - The Legio Tempestus came to the aid of their fellow Adeptus Mechanicus to assist the sacred Forge World from a large force of Traitor Titans. Due to the ongoing Sabbat Worlds Crusade the Legio Tempestus was only able to provide a token force but they were not at full strength, barely able to match the enemy forces unleashed upon Orestes. The Warmaster’s constant demands had drained the Orestes Forge of resources and forces, leaving them weak in the face of the Chaos attack. This put the Legio in an untenable position, and their forces suffered over fifty-three percent losses. The valiantly performed their duties until they were relieved from a large Titan battlegroup from the Legio Invicta.
