Legio Metalica - Notable Titans: Casus Belli - A venerable Imperator-class Titan, the Casus Belli was the leader of the eponymous battle group deployed by the Legio Metalica to destroy the Hereteks of the world of Nicomedua. The main armament of the Casus Belli was a Plasma Annihilator and a Hellstorm Cannon, although as an Imperator-class Titan it also fielded a main artillery battery -- which included a central Volcano Cannon -- countless self-defence lasers and point defence guns as well as numerous anti-aircraft systems. Through the corruption of some of the Imperator 's command crew, the Casus Belli was at the heart of an elaborate ploy by a secret Dark Mechanicum faction within the Metalican Mechanicum that sought to take control of the Casus Belli and turn it over to the Traitors of the Legio Fureans. Fortunately this plot was thwarted by the heroic sacrifices of Inquisitor Ossissuri Harkas and Magos Dominus Militaris Xaiozanus Xilliarkis Exasas.Doloris Dominus - A Warmaster-class Heavy Battle Titan of the Legio Metalica, depicted above during the Razing of Arcadiax in 009.M31, wielded a pair highly destructive Suzerain Pattern Plasma Destructors. These colossal weapons required immense energy to function. The Suzerain pattern was specifically designed to be wielded by the Warmaster Titan to allow it to fully leverage the extensive reactor system housed within the Heavy Battle Titan. This standard mode of fire saw the weapon function in a similar fashion to the Sunfury class Plasma Annihilator, albeit at a greater scale. When circumstances called for the destruction of hardened targets, additional power could be funneled into the weapon, focusing the unleashed plasma  into a concentrated lance-like projectile capable of melting through several layers of armour. This property ensured the Plasma Destructor was a slayer of god-engines, making it exceedingly dangerous for any Titan foolhardy enough to directly engage a Warmaster Titan.Custodire Faex - A Warlord-class Titan that was a part of the Hades V Battle Group that took part in the valiant defence of Hades Hive during the Second War for Armageddon against several Ork Gargants.Custodire Invidia - Custodire Invidia, a Warlord-class Titan depicted above during the Horus Heresy era, was the personal Titan of Princeps Seniores Ulrichit Larzend, known within the records of Metalica as the "Warden of Saraninent." This title was granted during the Great Crusade, when Princeps Larzend and his maniple found itself adrift following the redeployment of the 183rd Expeditionary Fleet. The vessels carrying Custodire Invidia and its kin emerged within the borders of the Saraninent Conglomerate, a Human enclave previously unknown to the Imperium. For a decade, the small contingent of Legio Metalica Titans led by Larzend fought off xenos pirates that had plagued the region for two standard millennia. When contact was reestablished with the 183rd Expeditionary Fleet, the Saraninent Conglomerate eagerly joined the Imperium and Larzend was honoured for his service under extreme conditions. To this day, monuments to the Legio Metalica exist across all of the Conglomerate's worlds, each dedicated to Larzend and his warriors. Millennia later in the 41st Millennium, this same Warlord-class Titan was a part of the Hades V Battle Group that took part in the valiant defence of Hades Hive during the Second War for Armageddon against several Ork Gargants.Custodire Pius - A Warlord-class Titan that was a part of the Hades V Battle Group that took part in the valiant defence of Hades Hive during the Second War for Armageddon against several Ork Gargants.Indomitable Guardian - A Warlord-class Titan that participated in the Subjugation of Nicomedua as part of Battle Group Casus Belli. During this campaign, the conduct of Indomitable Guardian was nothing short of exemplar, as it heroically saved the outgunned Omnissiah's Temper by interposing itself between its fellow Warlord and the incoming shots that would have destroyed it. Resolute, the Indomitable Guardian and Omnissiah's Temper held the line, even slaying a Chaos Reaver-class Titan before being forced to retreat as the enemy ground support marched onto the battlefield. It would take the arrival of the rest of the battle group for the foe to be defeated.Iron Splendour - A Warlord-class Titan deployed to Nicomedua as part of Battle Group Casus Belli, the Iron Splendour was the last Warlord to emerge from the storm-front that had disrupted the battle group's advance. With the Casus Belli again in Loyalist hands, the Iron Splendour played only a secondary role in the final battle against the Legio Fureans.Omnissiah's Temper - Omnissiah's Temper was a Warlord Titan deployed as part of Battle Group Casus Belli during the Subjugation of Nicomedua. Targeted by continuous fire from Traitor air support that stripped it of its Void Shields, the Omnissiah's Temper lost one of its shoulder-mounted Apocalypse Missile Launchers under the Quake Cannons of Az Khalak's defence batteries. After the fortress' capitulation, the Casus Belli ordered the entire battle group to press on, leaving Omnissiah's Temper unable to conduct the necessary repairs before it encountered the small force of Chaos Titans of the Legio Fureans that had previously eliminated Will of Iron. With the Casus Belli paralyzed by internal struggles, the Omnissiah's Temper would surely have been destroyed if it hadn't been joined by Indomitable Guardian. Together, both Warlords held their two Chaos counterparts at bay long enough for the rest of the battle group to emerge and tip the balance in the Legio Metalica’s favor. Blackened by fire from head to toe, the Omnissiah's Temper nevertheless survived to march again.Phlegmatix - A Warlord-class Titan deployed as part of Battle Group Casus Belli during the Subjugation of Nicomedua. The Phlegmatix was destroyed during the assault on the fortress of Az Khalak.Steel Hammer - A Warlord-class Titan that fought during the Second War for Armageddon and was the war machine of the Legion's acting commander -- Princeps Senioris Kurtiz Mannheim. Steel Hammer accounted for the destruction of three Ork Gargants before it was severely damaged. Not going down without a fight, Mannheim ordered his god-engine to be taken into the centre of the Ork forces before his Titan's reactor melted down. When the reactor detonated, a half-dozen Gargants were taken out, delivering a powerful message to Ghazghkull that the Collegia Titanica would never rest whilst a single Ork lived to taint Armageddon's soil.Legatum Virtus - A Warlord-class Titan that served with distinction during the Diamor Campaign on the world of Amethal alongside the Blood Angels' 1st, 2nd and 5th Companies against the Heretic Astartes forces of the Black Legion and the Crimson Slaughter. The ancient Titan was credited with several god-engine kills including 2 opposing Traitor Warlord Titans with well-placed shots from its powerful, thrice-blessed Belicosa Volcano Cannons. The venerable Titan formed the cornerstone of the counter-offensive that finally drove the Chaos forces offworld. The Legatum Virtus still serves together with the combat maniple called the "Storm Reapers" it fought with on Amethal to this day.Will of Iron - A Warlord-class Titan belonging to Battle Group Casus Belli. Will of Iron was lost shortly after the fall of Az Khalak. Advancing as ordered by Princeps Senioris Ieanola of the Casus Belli, the venerable Warlord was intentionally separated from the rest of the battle group. It was then destroyed by enemy Titans of the Legio Fureans which deployed directly from orbit and caught Will of Iron unsupported and unaware.Hammer of Metalica - Hammer of Metalica was a Reaver-class Titan deployed by Battle Group Casus Belli during the attack on the citadel of Az Khalak on Nicomedua. Stalled by enemy Shadowsword super-heavy tanks and fire from Az Khalak's Quake Cannons which stripped it of its Void Shields, Hammer of Metalica was left unprotected when the enemy called in an orbital strike. Hammer of Metalica’s death was so sudden that its Plasma Reactor did not have time to go critical -- instead the proud Reaver was consumed by the fiery energy at its heart as it toppled sideways.Labour of Battle - A Reaver-class Titan of Battle Group Casus Belli, the Labour of Battle was destroyed during the Legion's assault on the fortress of Az Khalak on Nicomedua.Laodoniz Vanguard - A Reaver-class Titan of Battle Group Casus Belli that participated in the Subjugation of Nicomedua. The guns of the Laodoniz Vanguard were essential in deterring the two Tiger Eyes Warlords from pressing their advantage against the stricken Indomitable Guardian and Omnissiah's Temper.Victorious Endeavour - Deployed alongside Hammer of Metalica, Labour of Battle, and Laodoniz Vanguard, Victorious Endeavour was the last Reaver-class Titan allotted to Battle Group Casus Belli.Hammer of Nyziroz - A Warrior-class Titan, the Hammer of Nyziroz was part of the second line of Battle Group Casus Belli during its attack on the fortress of Az Khalak. The timely intervention of Hammer of Nyziroz saved the Warlord-class Titan Will of Iron from becoming swarmed by hiding infantry.Sabreclaw - Sabreclaw was a Warhound-class Titan deployed by Battle Group Casus Belli during the Subjugation of Nicomedua.Steel Wolf - The Steel Wolf was a veteran Warhound-class Titan that served within the Legio Metalica for eight millennia. Designed specifically to clear out subterranean fortifications, the Steel Wolf was equipped with two Inferno Guns, a rare configuration for a Scout Titan. The Steel Wolf was lost on Nicomedua during Battle Group Casus Belli's advance through the Demetrian Plains. Slain by coordinated artillery fire, its demise was not a futile one as the incoming fire allowed the remaining Battlegroup to pinpoint the enemy artillery's position and annihilate it. Princeps Kash and its crew were able to evacuate Steel Wolf prior to the enemy's second volley, but Tech-priest Elaxha and her assistants proved not to be so fortunate.Woundwalker - A Warhound-class Titan deployed to Nicomedua, the Woundwalker was tasked with thinning the ranks of the Heretek Skitarii and Renegade infantry who hid in the heavily fortified Demetrian Plains. Equipped with an Inferno Gun and a Vulcan Mega Bolter, the Woundwalker accomplished its task admirably.
