Warlord-class Titan - Notable Patterns: Mars-Alpha Pattern Warlord-class Titan- The colossal Mars-Alpha Pattern Warlord Titan is among the most ancient and feared of the Imperium's war machines. Forged on the Red Planet itself, it is worshipped and venerated as the Omnissiah's will incarnate. Each god-engine is encased in layered armour and powerful Void Shielding, and armed with weapons that are capable of reducing armies to ash. In addition to its Ardex-Defensor Mauler Bolt Cannon and Lascannon turrets, support weapons that would be considered main armaments on smaller war machines, this pattern of Warlord is commonly fitted with a pair of carapace-mounted, triple-barrelled Laser Blasters and two Belicosa Pattern Volcano Cannons.Mars-Beta Pattern Warlord-class Titan - The Mars-Beta Pattern Warlord was one of several variant patterns that more readily expressed the power of the Machine Spirit (artificial intelligence) within the god-engine. This pattern was often used by the Legio Ignatum even in the Age of Strife prior to the founding of the Imperium. The Machine Spirit of this pattern was held to be especially aggressive and bellicose, even for a Warlord Titan.Lucius-Alpha Pattern Warlord-class Titan - The Lucius-Alpha Pattern Warlord Titan was a distinctively warlike pattern of the Warlord built by the Titan-Wrights of the Forge World Lucius. It took part in the Great Crusade and was seen on both sides of the Horus Heresy and later conflicts between the forces of the Imperium and Chaos. The Lucius-Alpha Pattern is known to be compatible with the parts used by Mars Pattern Warlord Titans, and this includes the entire head/cockpit assembly which is interchangeable between the two patterns.Proximus Pattern Warlord-class Titan - The Proximus Pattern Warlord is a variant built by the Forge World of Proximus for the Legio Invicta. Unlike some other patterns, the Proximus Pattern requires an amniotic connection for its princeps, and additional crewmen which includes a moderati, steersman, sensorii, and often a famulous as well.Warlord-Sinister-class Psi-Titan - A weapon of such hidden terror and secrecy that few even within the Imperium's hierarchy suspected its existence, the Warlord-Sinister was a thing that should not be. It represented the fusion of the most powerful battlefield military technology known to the Imperium -- the Titans of Mars -- and the "weaponised" power of bound Alpha-grade psykers enslaved and bled dry like living batteries by forbidden arcane technologies. Such arts, the merest hint of which would result in a death warrant for their creator, should not have existed, save for when its use was sanctioned by the Emperor Himself for use by one of the most covert of all the Imperium's agencies of war -- the Ordo Sinister. The  Warlord-Sinister was a variant of the more widely-known Warlord Battle Titan, and it was the only known "Psi-Titan" to be utilised by the Imperium during the Great Crusade and Horus Heresy eras. It was deployed in small numbers prior to the Horus Heresy, though rumours persisted as to the existence of other prototypes of experimental Titan patterns hidden even from the eyes of the Council of Terra during that period.
