Legio Perennia - Legion History: The Legio Perennia’s history is largely unknown and reliable information on the subject must be considered carefully. What is known is that the Legion was founded on Bronta-Mendian, in the Galileon temple-forge.The exact date and circumstance of this founding have been lost to time, but must have occurred only a scant few decades before the outbreak of the disastrous civil war known as the Horus Heresy.Its location on the Dextura shipping lane -- a well-traveled connection to the Segmentum Solar and especially the Sol System -- meant that Bronta-Median and the Legio Perennia had always been close to Imperial power, and were thus utterly loyal to the Emperor of Mankind.Following the Drop Site Massacre and the Schism of Mars, the ruler of Bronta-Median, the Fabricator Ancillarum Gaius Trasq, swiftly declared for the Emperor and was amongst the very first to recognize the authority of Fabricator-General Kane over the Arch-traitor Kelbor-Hal.With Terra making call-to-arms against the Traitor Warmaster and his allies, Gaius Trasq complied and despatched a full Battlegroup of the Legio Perennia to Terra. Battlegroup Astramax, as it was baptized, had only been recently commissioned and according to some sources, constituted almost the entire military strength of the Legio Perennia.Embarking upon the ark-freighter Omnissiax, the Battlegroup set out for the two-months voyage that would bring it to Terra, to stand in defence of the Imperial Palace or quite possibly participate in the reconquest of Mars. It is important to note that at the beginning of these events, the Legio Perennia was by all means a Loyalist Titan Legion, yet soon afterwards, its name would be cursed by those faithful to the Emperor that would die under its guns.Unknown to the Loyalist Mechanicum on Bronta-Median, the Omnissiax’s crew had been infiltrated by agents of the Traitors affiliated to the Alpha Legion. Worse yet, one of these infiltrators had clandestinely smuggled a full demi-cohort of fifty Traitor legionaries aboard the Omnissiax, hiding amongst the newly produced suits of Mark IV "Maximus" pattern Power Armour fresh minted from Bronta-Median's forges and production lines.When the Omnissiax received orders from Fabricator-General Kane to divert course to Callistra Mundi, an important world in the Gnostica System on which rebellion had erupted, the infiltration teams quickly disabled the Omnissiax’s means of communication and attempted to seize the ship.The numerical superiority of the Mechanicum forces proved insufficient to eliminate the Alpha Legion, as the Arkmaster settled for a stalemate which would eventually be resolved when loyalist reinforcements could be brought aboard from Callistra Mundi or the Omnissiax’s escort, the Mechanicum Light Cruiser, Dentilicon.To break this stalemate which would have undeniable turned in the Loyalists' favour, the leader of the Alpha Legion forces, Strike Commander Dartarion Varix, ordered the Titans of Legio Perennia, crewed by his own princeps and moderati -- which had also been smuggled aboard. Having gained control of Abyssus Edax, the Traitor Princeps Darieux turned the Titan's Gatling Blaster and Quake Cannon against highlighted positions of the Mechanicum, firing directly from the main hangar with Abyssus Edax still secured by its holding clamps.The Titan's firepower gutted the Omnissiax from within, annihilating the Loyalist Thallaxi and Castellax that were holding the Alpha Legion at bay and opening a way for the scions of the XXth Legion to storm the ark-freighter's bridge.Once in command of the ship itself, Varix ordered the Omnissiax’s guns turned against the Dentilicon which had approached to inquire what was the delay that had forced the Omnissiax to slow down and fail to power up its void-shields. With the last threat to his plan removed, the ship continued its voyage to Callistra Mundi to participate in the Harrowing ordered by Harrowmaster Armillus Dynat.
