Titan (Warhammer 40,000)

Titans, the supreme fighting machines of the Imperium, possess such vast destructive powers that they are able to destroy whole cities. When the aging princeps of the Warlord Titan known as "Imperius Dictatio" dies in the heat of battle, it falls to Cadet Princeps Ervin Hekate to fuse his soul with that of the Titan to master the raging war machine and save it and its crew from certain destruction.
