Legio Fulminata

"'I have an army!' 'I have a Titan.' - Conversation between the Heretek Azovar Kuul and Princeps Majoris Ajax, shortly before an Apocalypse Missile Barrage destroyed the former's citadel. "No single engine of war in the Emperor's arsenal is as potent or awe-inspiring as the God-Engines of the Collegia Titanica, even more so when they are deployed in together and alongside other Imperial forces. The only thing a Titan has to fear is fellow Titans or dedicated Titan-killing vehicles such as the Shadowsword Super-Heavy Tank. The God-Machines of Legio Fulminata are no different.

History
